Large Format Lens Resolution - tests from 1990's into 2004

Before my old Hevanet site goes away, I want to republish some of the early lens tests that Kerry Thalmann and I performed over 15 years of curiosity on the topic.

Test Results - Large Format photographic lenses


Kerry Thalmann and I tested the lenses found in the
table below. The emphasis is on compact portable lenses for use
in the field. Comments regarding these tests follow the
table. More information can be found at the links provided above
and below. This has been a long project and I hope people find
merit in being able to review this information on-line.

You can use the following to 'jump' to the desired
section of this test page.


Please note: Take care in comparing lenses.
Some were tested from f/11 to f/22, while others were tested from f/16
to f/32, and still others from f/18 to f/32.

Please NOTE:

  • This is at best a relative (not absolute)
    comparison between these lenses. Kerry and I are simply looking for the Pick
    of the Litter
    .


  • All lenses tested at 1:20 magnification (a
    typical working distance).

  • Test setup was TMax100, D76 processed to my
    system's calibrated exposure/time/temp

  • Canham DCLH(?) metal field 4x5, Linhof Tech III,
    Linhof Master Technika, Linhof Master Karden, and Tachihara wood field
    4x5

  • Edmond Scientific Lens Resolution Chart

  • The negatives were exposed for Zone 7-8 for
    detailed white and Zone 3 for detailed shadow.

It's also important to remember that things that
influence system testing include:



  • Camera alignment

  • lens quality

  • ground glass plane accuracy (which influences
    holder accuracy)

  • film's granularity

  • light source (narrow band blue will test better
    than narrow band red)

  • film sag/bulge/droop at focal plane


  • test pattern



As a comparison, I include Larry Whatley's test
results.

Here is resolution data of a Kodak 203mm f/7.7 Ektar,
measured in the film plane with an eyepiece. (Thanks, Bill F., for
lending it!) This is a very good lens, usually at a modest used price.
Corners for this lens are at 21 degrees for 4x5 and 27 degrees for 5x7.
Angles here are half-field angles-- angle from the optical axis. Notice
that you need to be a little careful in using this one for 5x7 if you
want the corners sharp.

A short pause to consider...

I have been running two or three sites on the internet for many years now. I started by hand editing a web-site that was hosted by our ISP. It became somewhat popular for it's large format and medium format lens testing that Kerry Thalmann and I performed with film cameras and systems. I posted a few other "reports" on cameras and image quality.


Jinn ~ Bogville


The time for "hevanet.com/cperez" to end has come. With a move out of the US, my wife and I will no longer need nor use our old ISP. It's been a great service and I have learned a lot about web sites and what to do and what to avoid.

Shortly after a friend recommended Flickr, I joined and started posting my palladium print images. I thought I would put a few works in progress up on the site and see what happened. I quickly learned that Flickr was a great site for sharing images with a very broad group of viewers. I also learned to contribute to different "groups" on that web site. I witnessed the power of what I'll call the collective viewing of images.


Dandy ~ Bogville ~ Gypsy Dust


It all started 7 years ago.

I can look back over these 7 years and see how my image making has improved. Vastly, some might say. I started by posting images made with film cameras and quickly transitioned to posting images made digitally. With this change in technology came a rapid increase in productivity. It was easy to review my results publicly and to make changes in successive image projects.

The statistics page tells me that my work has received well over 1 MILLION views in 7 years.

Think about that a moment.


Rachel Brice ~ Art Nouveau


What gallery could you hang your art in where you could get these kinds of "eyes"? What public forum could you use the feedback you receive to hone and shape future work?

It boggles my mind. Truly, it does.

I know the approach works well for me because of all the work that's been published and all the fine creative people I have met through Flickr.


Baron's Wraithe


This set represents the images that I think work well and express my vision in the best possible manner. While not thematic, perhaps you can see how my work relates across time, across ideas, and across bodies of work.

My images have been published worldwide in the following locations and publications -

A steampunk book published out of England sometime this summer, 2012.

"1000 Steampunk Creations: Neo-Victorian Fashion, Gear, & Art", Curated and presented by Dr. Grymm, with Barbe Saint John, copyright 2011 by Quarry Books, pages 60 and 61 (USA)

"Victorian Gothic", Images published across 16 pages of Silvershotz Magazine, January 2011 (Great Britain)

"In the Railyard" Selections from a larger work published in The Center for Fine Art Photography's "Portfolio Showcase, Volume 3" (USA)

"Age of Steam" ~ New Visions, published in November 2009, Photolife Magazine (Canada)

"In the Railyard" ~ LensWork Magazine, Extended issue #78 (USA)


Seraphic Society - Shelley Frederick, Viola Rose (Butoh)


I have connected with the Bohemian culture in the city I am moving from. I have worked with some of the the world's finest performers, dancers, actors, tailors, seamstresses, and musicians. I have helped share with the world the beauty in their art.

As we prepare to make the jump to Paris, France, I have made connections with publishers and editors there, as well as made the first tentative links into the Parisian steampunk community.

I'm looking forward to continuing to create images, regardless of where I live. Flickr helped me share my work worldwide, and I know whatever I do, I will continue to post and publish my art through this incredible medium.

Saying good bye...

My wife and I have been visiting our family over the past three weeks. The first came as part of our Visa trip to San Fransisco. The second came as a deliberate trip to the south coast.


Bandon Lighthouse


It feels rather strange to say "good bye". Everyone is very supportive of our move and are quite surprised at how rapidly everything is coming together. It will be around 5 months from the time I was laid off to the time we arrive in our new home, Paris, France. This will have covered everything from healthcare insurance and Cobra costs, to selling the house, downsizing dramatically, selling things we don't need nor want, getting the French Long Stay Visa, to packing and moving.

Yikes! Lots to do.

It's felt like we're running a marathon at a sprinter's pace.

I realize that it's far too early to have any perspective on what we're doing. This, even though people tell us we're their vanguard and that they're very excited to see and witness what might be possible for even themselves.


Petaluma Abstract



To keep myself focused and to form a bridge between this life and the one we are running to, I've been in contact with various people in Paris.

My creative life has included making a lot of photographic images. One of the great joys has been to connect with creative people with whom I can work. They bring their style and talents in exchange for my photography.


Petaluma Textures



Two wonderful connections already made in France. One person is a photo-magazine editor and the other is with a Paris Steampunk group.

It will likely take a few months, if not a year or more, for me to develop any perspective and to lay claim to any lasting judgement about what's happening. For now, it's one foot in front of the other and to keep going...

... back in the dim and distant past...

Back when dinosaurs roamed the earth and well before I got a "real" job, I worked in Hollywood as a B&W print maker. The shop was on Sunset Blvd and was an extension of Samy's Cameras, which was just down the street.

It was an interesting place to work. One of the guys who worked in the building (for an unrelated business) had a Lamborgini Mura S that he'd drive into work every now and then. I could hear it start up in the afternoon, even as I was deep in the dark cave of the darkroom. What a great sound it was!

We used to print lots of rush jobs for all kinds of folks. Photographers and "gallery" owners and just plain 'ol mom and pop kinds of people coming in, literally, off Sunset Blvd's sidewalk.

One rush-rush job we got was from a guy who had a stack of negatives that he wanted "proof sheet" like quality prints from. Just throw them into the enlarger and "let 'er rip!", he said.

Of course he wanted to "approve" the images before he paid for them and could walk away with his proofs.

I was handed one stack of negs and my colleague was handed another. In my stack was a rather poorly exposed very difficult to print 4x5inch negative of Clark Gable.

My first resin coated print was junk. I quickly fine tuned the exposure and tried a very fast burn effort along one edge that was particularly "blown out". Out of the Kodak quick printer came the second RC print and off to the front desk for approval.

While it was out being looked at I grabbed an 11x14 sheet of Kodak G double weight paper and set to work. The first print was also junk. Even though I had an excellent sense of exposure, the image needed to be torn up. It just didn't "work".

Putting a second sheet of Kodak G double weight into the easel I made my second exposure and burned the hell out of one corner. Just as I dropped the paper into the developer, the front desk lady came in a retrieved the negative.

I finished off the print and took it home.

I was SHOCKED when, three months later, I visited a local shopping mall and walked by a poster shop. In there was the print I'd made on RC that I'd considered junk. It was a poster made from the "proof" image of Clark Gable!

I couldn't stand it. All the guy had to do was wait another 10 minutes and I could have given him a real print. Something worth hanging. Rather, what the world ended up with was just absolute garbage, as far as I was concerned.

It made me sad.

But, I still have the 11x14 inch Kodak G double weight original. It still pleases me, even after all these years.

Resolution and Wishful Thinking...

I've been on conversations with fellow engineering colleagues where, over the years, we tend to note just how disconnected from reality some people are who make claims about resolution and it's effect on photographic image making. Typically, arguments arise in on-line forums where someone will claim that Zeiss lenses are "the best" and someone else says Leica "can't be beaten", and all parties claiming they can tell the difference in images made with different lenses. DP Review is pretty typical of this effect.

The claim that really takes the cake is the one Zeiss and other manufacturers use when they say a lens "writes" well. What the hell is that? Optics are optics and physics is still physics. It's all bunk. There's no truth to those kinds of claims, no matter what some folk would like to believe.

In optics, lens design, when well-executed in manufacturing, tends to not be the limiting factor in resolution. It's either the film or the sensor (depending on which technology you use).

The following is a chart of theoretic limits of resolution of a perfect lens at various apertures.

Resolving Power


This presents the theoretic resolving power of an ideal lens where the light's
wavelength is 589.3mu (green).


Tangential lines/mm
f-number Angular distance from axis (in degrees)
0 10 25
1 1391 1329 1035
2 695 665 518
4 348 332 259
5.6 246 235 183
8 174 166 130
11 123 117 92 <--- approx. limits of film/sensor resolution
16 87 83 65
22 61 59 46
32 43 41 32
45 31 29 23
64 22 21 16

Radial lines/mm
f-number Angular distance from axis (in degrees)
0 10 25
1 1391 1370 1260
2 695 685 630
4 348 343 315
5.6 246 243 223
8 174 171 158
11 123 121 111 <--- approx. limits of film/sensor resolution

16 87 86 79
22 61 61 56
32 43 43 39
45 31 30 28
64 22 21 20



Which means that diffraction limits really can't come into play in any meaningful manner until a lens is stopped way down to at least f/11. Even then, most modern digital sensors are resolution limited to around 70 lp/mm. So with those systems (such as with either Canon's, Nikon's, or Sony's full frame sensor'd wonder boxes), diffraction in the pure optical physical sense will not come into play until you're well beyond the limits of what a lens offers. ie: f/16

As sensor resolution rises, diffraction will still not come into play as many photographer shoot at apertures brighter than f/11.

Said another way, I've never met a lens I didn't like. Some, yes, I liked more than others. But seldom, if ever, were the issues of "liking" a lens related to it's ability to be sharp.

I've shot them all. Leica. Zeiss (small, medium, and large formats). Canon. Nikon. Pentax. Mamiya (medium format), Schneider (medium format, large format). Sigma (I know people claim to hate these lenses, but I can't find fault with them, they're wonderful optics, regardless of money). Dagor (large format). Kodak (small, medium, large formats - brilliant optics from WWII until the mid-1960's).

It's not a matter of the lens. It's the nut behind the eyepiece.

So there. Now go out and make some fine images. Forget about the blather on those forums. OK?

A funny thing happened...

My wife and I have been going to the Ridgefield National Wildlife Refuge up in Ridgefield Washington for three or four years. I wanted to go because two of my then colleagues, Rick Cameron and Rob Sanford, would come back with wonderful images of a bird I've never seen before. They told me it was a Bittern.

Their images were to fun and interesting that we'd trek up there from time to time to see if we too could find that funny shaped bird.

We never found him.

I accused Rob of taking a stuffed Bittern and placing him by the road at RNWR just so he could take a "realistic" image. Rob and Rick both laughed and told me how easy it was to find them.

They didn't tell me how illusive the Bittern could be. No. They just continued to laugh at my predicament.


RNWR - Bittern



Once. Just once, we found a Bittern. I took his photo and was thrilled. But that was three years ago.

On recent a Sunday when our house was being shown (it was on the market for sale) and there was some silly National Holiday Sporting Event on TV, my wife suggested we go to RNWR to say goodbye to all our feathered friends. One last time.

All our bird friends were there. The Tundra Swans, the Shoveler Ducks, the small song birds, and the big Northern Harriers were all out giving us a winged farewell. Everyone but the Bittern.


Bittern



We were cursing the Bittern for his illusive ways.

We came around the south edge of the loop, muttering all the way. "Where is that Bittern?" "Where, oh where is that Bittern?"

Coming around a corner, my wife asked again "Where is that Bittern?" I said "There he is!!!"

Not 20 feet from the car was our funny Bittern friend. He was so close that if I used all 400mm's of my Canon 7D/100-400L combo, I only caught the Bittern's head.


Bittern


He'd come out to say goodbye too.

I'll miss them all up at RNWR. Such a beautiful place. Such a peaceful area.

It's time to go. April 11th is our pending departure date. The house is sold. Our things are packed. Paris awaits.

Did I really get to work with Rachel? Pinch me. I must be dreaming.


Rachel Brice ~ Springtime


So... what would you say if the world's finest bellydancer's agent contacted you and asked if you could make a few images? Would you A) Say, thank's but I'm booked? B) Scream and hollar, jump up and down, and run around like a chicken with it's head cut off? C) Suddenly get worried that the Muse, in all her loveliness has left you? D) B and C?

I've heard of Rachel for several years and made a rather terrible video of her during a local event. Imagine my surprise when, in spite of the video, I actually got to work with Rachel and Sol?

What I've come to realize is that creative people are creative through and through.


Rachel Brice ~ Springtime Renaissance


There was a photoshoot that I did for a Steampunk theme set where a model came in with her entourage and tried to "own" the place. Rather like they knew what they were doing. But, as you can likely already guess, they were just young and inexperienced. They'll get better with time and we came away with a few good images (which have since been published).

When I work with true creative people (professional or not), the essence of who they are, what their craft is, and how they live in the world comes through, loud and clear. The Baron Samedi photoshoot was just like that. Scream'n hot great images from the "get, go".

Such was the case with Rachel, too. Solid. Centered. Clear vision. Just perfect to work with from the outset.


Grace of Rachel


I've since spoken with one of Portland's leading photographic lights, Ted Mishima. He is a great artistst and is staying true to his vision. And we get to live his dream. Ted and I spoke a number of years back and he mentioned how fun it would be to work photography in an atelier in Paris, France.

Little then did I realize that my wife and I would be moving there. Soon.

After working with such fine people in Portland, I'm a little worried about being able to find such high caliber folk in Paris. Funny, isn't it? Yet, there it is.

If I'm lucky, creative people will like what I do there and my wife and I will be able to work with them too. I'm keeping my fingers crossed for good luck.

In the mean time, I have a LOT of potentially fine images to work from in our shoot with Rachel, and Eyerish, and Danielle, and....

Something wicked this way comes...

As a sometimes neurotic artist, I wonder if my work is "good enough". Every now and then, I take a look back and realize, to me, it's better than I could ever imagine I was capable of.

Perhaps it comes from working with such talented people?
