Medium Format lens tests

Here is another page from my original "hevanet" website devoted to camera system/optics/film testing -

Medium Format Cameras - Testing Lenses

Last Updated: 19 April 2004

Medium Format (120/620)
Camera / Lens Resolution Testing

Please note: there are four sections found on this page. Each section represents a particular camera type. There are sections for SLRs, TLRs, Coupled Rangefinder Cameras, and Folding Cameras (with coupled and non-coupled rangefinders).

Notes:

***It appears that the Rollei lens may be quite fantastic. Just look at the edge numbers! But the lack of accurate top lens calibration (happened sometime after leaving the factory) is enough to cause serious sharpness issues. The Mamiya C220 or Yashica didn't have this problem...
1. It appears that film flatness is a serious issue with some medium format cameras. It may be that 120 film "bows" in the middle of the pressure plate for some of the cameras tested. It shows up most frequently when shooting 6x9 (2 1/4 x 3 1/4) format cameras and film backs and earlier Rolleis.
2. Many camera lenses were tested at 20:1 distance to focal length ratio. Those that weren't are noted in the above table. For 75mm/80mm lenses this works out to 5 feet from the test target or 50 to 61 inches. For 100/105mm lenses this works out to 7 feet from the target.
3. For folding cameras the target proximity required that the distance be calculated using a tape measure and the lens being tested was set to that distance on it's scale. If the distance scale on the lens is mis-calibrated then the lenses optimum resolution would be compromised in these tests. In many cases this 'reality' is borne out in the test results. In 'three space' many of these systems will perform better than shooting against a 2D target would suggest.

Test Conditions-

All tests were made using Kodak's TMax100 film, processed in D-76 to my system's requirements (zone system), and viewed under 40x magnification.

All cameras that supply direct focusing were tested as a system using the focus provided by the direct mechanism. In the case of the Muscova this is a rangefinder (which may not be accurate as the system tested poorly at 7 feet). In the case of all TLRs and SLRs the focus was set using the std. groundglass.

Photography costs!

[This was cross-posted to my Retiring out of America blog]

Yesterday evening I decided to make a few images of la tour Eiffel from out the front window doors. This time I wanted to make some very high resolution photographs. This involves taking multiple overlapping photographs of a scene and then stitching them together after the work is downloaded off the camera.

I set up the tripod and worked on the scene from around sunset until just after 2200h.

At 2230 the door bells rings.

Ancient Photographer (me): "Qui est-ce?"

La Police (the oldest of them): "La police."

Thinking as fast as I could about home invasion robberies and the likelihood that these aren't the police, I took a chance and opened the door. I was greeted by three men in normal street clothes. One showed me their badge and said...

LP: "Vous prenez des photos, n'est pas? Votre voisin nous téléphonons. Vous avez une télescope, oui?"

Center section of la tour Eiffel - 100% crop

It turns out, someone across the street from us in the general direction of la tour was concerned I was taking their photo!

AP: "Non. Je n'ai pas une télescope. Mais, oui. J'ai pris des photos. Et, je ne m’intéresse pas de mes voisins. Ce qui m’intéresse est la tour Eiffel."

If the man wanted to see a real telescope, I could have showed him a big brass monster that someone across the way keeps in their window. No doubt for star gazing purposes. Hah!

LP: "La tour Eiffel?"

AP: "Oui."

He then asked me to show some ID and show him the photos. But I was a little peeved and asked about how they were clothed.

LP: "Vous n'avez pas de police dans les États-Unis?"

AP: [gestering to my clothing] "Pas comme ça! Et, ce qui concerne votre identité..."

There must have been just the right tone inflection and indignation as the officer went on to explain they were from the Municipal Police and all they were going to do was go back to the caller and explain I wasn't taking a photo or acting as a "peeping Tom." The other two police showed me their badges as well.

Near the very top of la tour Eiffel - 100% crop

About this time, Jude shows up at my elbow and peeks around me to have a look. She, it turns out, was concerned about the same thing I was. Home invasion.

AP: "Bouge pas!" [turning to get my passport and camera]

My wife locked the door behind me, but not before I heard the officer saying "... oh, rest assured, I'm not going anywhere..." I knew I'd hit a cord, yet I had no idea if it was "good" or "bad". AND having the door locked behind me must have really driven home a point. Again, I'm still not sure which point that might have been.

After showing my passport, giving our telephone number, and showing the officer the images of la tour, they bid us a "bon soir" and left.

Jude asked me "Did they really think you would be taking photos of someone in their apartment? You should've told them "If the person who phoned you is so pretty that they need to be concerned about other people sneaking photos of them, you should have brought them with you so we could've had a look-see for ourselves.""

Funny thing was, while being indignant and trying hard not to be too condescending, I was thinking exactly the same thing.

Alas, my French language skills are several light-years away from that level of banter. Particularly with the "authorities".

Old stuff...

Here is an interesting bit of news. An early prototype Leica just fetched 2.16MILLION Euros at a recent auction. That's a far amount of money for something that used 35mm movie film stock.

I suppose I'm not sure how I feel about that amount of money changing hands for a prototype instrument.

Vintage image? Or not? And does it matter which it is?

On the one hand, it could be viewed as an interesting bit of history. If so, then it should be put in a museum somewhere. On the other, it makes me wonder why anyone would feel this particularly instrument would be worth that kind of money.

The BBC article notes that "The prices such cameras fetch show the growing interest in early photographic materials."

If this were true, then why these small format cameras and not some of the potentially fascinating equipment from the mid-1800's? After all, there was an incredible explosion of engineering creativity at the birth of photography.

What was used to make this image? Does it matter?

I think of Petzval formula large format lenses. They were mathematically designed to render out of focus areas of an image in very specific ways. Few equivalents exist for small format cameras today. And the lenses which do similar things to the Petzval likely achieve the effects quite by accident, not by design.

That is just a simple single example of something I feel could have incredible value at auction. If only people understood what went into the making of very early photographic instrumentation.

Then I think about tools of creative expression. Would this kind of money change hands if it were, say, one of Matisse's paint brushes or a have used glob of Rembrandt's paint?

I suppose the dictum is true: How we spend our money is a direct reflection of our values.

What is valuable in this? This exercise is left to the reader to sort it out.

... oh... the active mind...

Before we moved to Paris I nearly sold my Nikon manual focus fast apertured lenses. In fact, I did sell the incredible 180mm f/2.8 Ai I owned. Fortunately, I kept nearly everything else, including the 24mm and 35mm f/2 Ai lenses, a 50mm f/1.4 and the very sharp 85mm f/2 Ai.

While visiting the Montparnasse Cemetery to say thank you to Soeur Rosalie, I took just a few moments to try my hand at making three images. So far I have processed two of them and find that I'm very pleased with the results.

The technique is rather straight forward. Take one Sony APS-C sensored NEX5 and mount up that nice Nikon 50mm f/1.4 and shoot it wide open (you might need a ND or Polarizing filter to knock down the exposure in full sun). Put the camera into Manual exposure mode and meter the most important part of the scene. Use that exposure for all shots in the sequence that follows. Take a series of overlapped images somewhat near the primary subject, spilling the scene well beyond the subject so as to make sure you have covered the scene with enough room to work with. Stitch the images using Hugin's latest version of open source software or the University of British Columbia's "Autostitch" trial version. Save a sufficiently large result of the "Ransac'd" output (I like 6000x6000 pixels for the level of resolution I get in the final processed images). Process to taste.

Yes. I think the technique works.

It reminds me of shooting 4x5inch large format film using old fast optics shot wide open. I LOVED those old cameras and lenses and sometimes miss the technique. Alas, in the digital age my output has increased so dramatically that I can't go back. So I'm very happy to have found a hybrid approach that helps me achieve the kinds of things I used to dream of doing in 4x5.

All it takes is a little vision and away you go!

Now the my wife and I are settling into our new home I have a little time to expand my vision and see if I can't plan to make a few nice images.

First, I need to work a few new techniques to see if I can't express the previously un-expressable.

I have to say, it's very exciting to be surrounded by so many incredible opportunities and such a wonderful sense of life and living.

The wine and foods here taste better than I remember them, and we were here only 7 months ago!

The shopping and walking is getting me into shape, I hope, for making the photographic connections into Paris' creative arts community. I can't wait for our first serious shoot here. It's possible that it'll be with the Steampunk folks.

Oh man! this is just too good to be true... the risks taken and the work it took to get here are, so far, very much worth the effort...

Here we go...

What a journey!

My wife and I arrived in Paris earlier this week. Like my wife said, we'd take a couple weeks to do nothing but sleep. I sure feel tired.

I had taken a two month hiatus from taking images. It has been rough, from an artistic perspective. It felt like I was loosing my "vision", or at least it was becoming stale.

Yet, it was well worth taking a break to keep our heads down and concentrated on making the move as smooth and efficient as it was. We moved a few things into storage (a 10x10foot unit) and packed our entire lives into five 29inch suitcases. When the Big Day arrived, we climbed onto a one way flight to Europe (with IcelandAir) and went through Iceland customs where we received our Entry Stamp valid for our one year Long Stay Visa.

In total, the entire process of being laid off after 30 years of working in high tech, receiving our first bill for COBRA (WAY too high at $1100 per month), deciding to live a new dream, preparing and putting our house on the market, having it sell in 7 days!!!, flying to San Fransisco to apply for our visa in person at the French Consulate, finding places for all our things in downsizing our household, packing and making the Big Jump all happened so very quickly. It took five months and 10 days to change our lives in such a massively complete manner.

Once we landed and started to settle into our new apartment I felt inspired by the view out our front window. I had to create a new image.

This is partly what the world presented and what I saw in my mind's eye. It'll be interesting to see where this leads.

... so... it was a short drive...

The last post I said it was driving me crazy. The "it" being that I have no new images nor the time to work on them.

Well, enter 30mins and a new set of ideas.

I took an earlier image of Sushila and worked it in the style of a Louis Vuitton advertisement. I did not like the results.

What to do? Keep going.

It tried a little of "this" and a little of "that".

Et voila! An image that nearly makes me happy. The parts that don't have to do with the texturing and the colors of the textures. These things can easily be resolved.

Now, to continue packing and making sure we can fit everything we will live on in 5 29inch suitcases. That is just how small our lives have become after deciding we want to live experiences and to stop collecting "stuff".

It's driving me crazy...

While we're in the process of moving out of the US, I've had to put my image making "on hold". It's driving me nuts

I love the creative process and haven't had a moment to spend working any of the images that interest me. Further, it'll likely be at least three months after landing in Paris before my portable studio lighting, backdrops, and stands arrive.

I'll have my wee-point and shoots (Sony NEX5) as well as my big DSLRs with me. So local "touristy" images are likely all I'll get to make for awhile.

The things that are really calling me are related to the themes of Steampunk, Oilpunk, and Retro-Future. I can "see" the kinds of images I want to make...

... patience... patience... patience...

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.

last updated: 04/19/04

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.
