Industar-61L/D Fail

So I have a 1990 Industar-61L/D, the glass is not visibly yellow, yet I get a very low contrast and very murky yellow haze in the images wide open, which improves a bit at F4. Overall, the contrast is quite weak, and not as sharp as others seem to have it. The day was extremely overcast, and the lighting was totally flat so it's definitely a worse-case scenario as far as lens performance goes. I was astounded by the amount of flare caused by the blank sky alone! It's supposed to be multicoated but I get the impression that it might actually be better if it weren't coated at all...

For example, adapted to my Panasonic GM1 2x crop, shot in RAW, WB at 5500K:

At F2.8:


At F4:


Minolta at F2.8:


Industar At F2.8:


Industar At F4:


It was also disappointing to see that the Minolta Super Rokkor was as detailed at F1.8, and more detailed and clear at F2, than the Industar was at F4... maybe not surprising to some but I had faith in the Tessar. At least it did appear to have a much flatter field than the Minolta, unless I did something wrong with my focus and framing - resolution fell off steeply with the Rokkor. I'm sure I have a poor copy of the Industar but are they all this bad? I mean, the resolution is not terrible given its diminutive size considered, but this lens has a reputation for strong contrast and good sharpness.

I have the same lens, both normal and l/d, not the sharpest or most contrasty but usually better than your first two examples.

I have the same lens, it's definitely not as flat as that...

I tested it again indoors with a ceiling light not within the scene, but above the camera so I can confirm that It's flare into the lens reducing the constrast and not a problem with my adapter... so I guess the lens needs a deep hood. It's the first lens where I've ever had a problem like this - for a 1971/1990 coating, it's... rubbish. I actually can't believe it is so bad. Did you guys test without a hood too?

I used mine 3 weeks ago on my a7, no hood. 1985, non l/d, black and silver version, orange coating.

f4 or 5.6


2.8


2.8

Yours seem to have better contrast than mine, and without the golden flare. Unless there is something not at spec about my lens/lens coating, I'd guess the flare may be extra reflections of the sensor stack of my camera. I checked my adapter and there is no light leak. I must take a few shots with it on film to see if it's the same.
Thanks for your replies.

Looking at the images only, I would guess it has a thin film of haze on one of the interior elements.

Something is wrong with your lens. Check that the interior surfaces are clean and that the rear light baffle is in place.

I CLA'd this one, these are test shots on the M9.

This is a very good Tessar formula lens.

Buy another one. They are ridiculously inexpensive for the quality of optics you get.

Taken without a lens hood on a Canon 5D3...

Always buy the 61LZ,close focusing,deeply recessed no need for hood and it performs rather well.....
