The "look" of three 50mm

[raid]

To complete the above, I don't think that a test should be only about flare and flare control, and that's why I am inclined to autoadjust the scans. Contrats will still show. Of course, we could push this test to the limit by having another roll of scans in which each scan is optimized, refelcting the true world applications. The user would most likely do so.

Do you know how I can obtain place for posting many files?

I'd say adjust them except for any sharpening. That seems to hash things the most.

William

Agreed as I think lab-prints do some levelling as well (correct me if I'm wrong).

 

[raid]

I used an enlarger stand, LTM to F adapter, and Nikon D1 for the 5 j-3's.

Same CCD to rule out varience on film/processing.

Used the Focus Confirmation rather than trust my own eyes.

It cannot get more boring than that.

Brian: Your testing is "clinical". I cannot do what you have done since I don't have an enlarger.

 

[raid]

OK then I will do some gentle autoadjusting or fine-tuning and hopefully post at least some of the scans tonight. Now I need to drink some hot tea ...

 

[FrankS]

Okay, I'll go have some red wine and watch the hockey game. See you later.

Brian: help me out please. How do I post on the Gallery in RFF? I have not done this before here.

 

[raid]

I was allowed to post five images in the Gallery. I posted results for five lenses and will tommorrow post five more. Let me know what you think of the initial results.

 

[back alley]

if adjustments are made then the same adjustments need to made for all pics, same settings etc.

 

[ChrisN]

Raid - as Frank mentioned, you need to isolate the variables. If you can guarantee the precisely identical post-processing on every pic, that would be ok. Otherwise its better to post unprocessed pics. I think auto-adjust might be different for different pics.

Edited to add: Great work too btw; I'm looking forward to the results.

 

[ChrisN]

Raid - good work.

Your model is very cute! 🙂

I love the Canon 1.2 (gotta get mine fixed!), and I was surprised at the amount of flare from the Summicron collapsible and the J3.

 

[raid]

Chris: You will be more surprised at the flare I got in the photos that I could not post tonight. It was shock to me to see so much flare in Summicron lenses and a Zeiss lens. I never before tested for flare and I did not see any because I avoided shooting against a light source.

Here is a link to the image by the Canon 50/1.2 @ f2.0.

This is a better link for all five photos side by side.

I wish I could have posted all eight images side by side or at least have them tonight up here in the Gallery. In my next tests I will control flare and check other properties of these lenses. Maybe some of you could make suggestions on what to test.

Looks like the Canon's are doing well. I expected the 1.8 to look good (since I have and know one), but the 2.8 is very interesting to me. Just goes to show what a well made Tessar can do. I'm looking forward to the rest. Any comments on particular lenses while we wait?

Brian: I actually meant posting in the Gallery, which turned out to be easy.
As for comments I have on the eight lenses, the big disappointments for me were the German lenses when it comes to flare control. The Rigid Summicron did very badly with flare and the Zeiss Sonnar did even worse with respect to flare and lack of contrast.

Raid, I hate to say this, but the test will likely failed ... Reasons? .... The model is tooooooo cute!!! I can't focus on any optical differences... only the expressions 🙂

Good job, can't wait to see the rest 🙂

Thanks. My model got chocolate as a reward for sitting quietly for quite some time on the chair while I changed around eight lenses.

I'm surprised the Summicron flared so badly. Have you checked it for internal haze? I've had mine in similar circunstance and not had a problem like this. If the Sonnar is uncoated, I can believe the flare would be bad. I have an uncoated 5cm F2 that flares, but the coated 5cm f1.5 Sonnar does not. The surprise performer for flare is the 50mm F0.95, I've shot with the sun in the frame with very little flare.

And I certainly agree about the cuteness of the model in every frame. I'm also glad to see those curls in focus with the J3.

Brian: I will check out the three lenses that failed the flare test;
1. Rigid Summicron
2. Collapsible Summicron
3. Zeiss Sonnar

I hope that it is just removable haze.
As for the J3, I also am happy that focusing is fine.

My Sonnar is uncoated to the best of my knowledge. There is no color visible from the front. The Summicrons are the surprises to me. Hard to understand why they flared.

IIRC, Raid, the collapsible and the rigid ARE known to be flare-prone, compared to the more modern versions.
