Anybody have any experience of this lens they can share? I have a 3.5/35 Super-Tak that makes green pictures so I've been thinking of upgrading to this one, but it's quite a lot more expensive. I already have the Flek and Mir-24M, how does the Tak compare?

Many older Takumars experience a yellowing of certain (radioactive?) elements - perhaps this tinge is due to this? If you expose the lens to sunlight in a window sill with the caps off and diaphragm open for a month or so it'll clear up.

If you get the urge to use the lens in the meantime, just use a little white balance.

There are several interim stages of Takumars from Super-Tak to Super Multi-coated to S-M-C (I think thats the correct order). There may be a difference in coatings, but in practice with the ones I've used, they all looked really nice.

I really like those pics btw - particularly #1 and 3.

Thanks Kelly. Good thinking, but the S-Tak 3.5/35 doesn't have the Thorium element and is not supposed to yellow. There's no obvious colouring of the glass at all.

I took several pics on the same roll using a S-M-C Tak 1.4/50 which certainly has yellowed. I don't know how to use WB with film scans, I use the Curves tool in PS CS2. Here's an example of the yellowing and corrected with Curves:

You're one step ahead of me! I forget I've joined a forum of devotees to the cause here. Maybe instead of a radioactive element they used a biohazardous one in that lens Laughing

I want to say though, no slight to your PS work on the yellowing example, but I think you've just convinced me not to de-yellow my Super-Tak. The yellow caste in the original shot adds something for me.

I'll be curious to see if a solution is found here, good luck.

Strange result !

I have the same lens, no green. Weird.

I also have a very yellow Takumar 50/1.4, and I like it that way. I think its "golden".

Thanks Kelly. All thoughts and contributions are valuable even if they just make you think twice, which you did! Don't be discouraged.

I have absolutely no idea why the pics turned green. I have tried scanning the negs in all three modes of the Epson software, and with Vuescan and Silverfast and the results are always the same. The lens is perfectly clear to the eye.

The yellowing of a Thoriated lens happens when it is stored for many years with the caps on and/or in a closed camera bag so that no light can get to it, and it starts to cure as soon as light enters the lens again. Putting the lens on a sunny window cill just speeds up the process. If you want to maintain the yellowing you'll need to keep it in the dark and only use it occasionally, but even then I think it will cure itself eventually, albeit over a much longer period. But don't worry - you could always use a filter! Wink

See if you can take a picture with it on a digital camera. If the result is the same, then you can discount the medium. And it's much easier to adjust the colour balance.

I have SMC 35/2 and old (big "PRO") version of Super Takumar 35/2. The new small thoriated one is not better than 35/3.5 - more CA, less sharp, more purple fringe. It's only faster - results at f/2 or f/2.8 are not bad, but for higher f-stops 35/3.5 is better.

The old big PRO version of 35/2 has lower CA and purple fringe, at f/2-f/2.8 is less sharp (no MC), but it's sharper further - similar to 35/3.5, but slightly lower edge resolution.

I forgot: Here is my comparision of the three Takumars:

I have no problem with green tint, I have no idea what could be the cause.

Patrick, thanks for the idea - doh - why didn't I think of that? Wink Some very quick and rough shots with the 400D this morning don't have an obvious green tint like the film shots, but certainly look very cool compared to the Flek, which has about the most "normal" colour temp of my lenses. Also the sunshine today is much brighter than the gloomy day I took those green shots so that may be a factor.

No-X, thank you very much indeed - exactly what I was looking for and very interesting results too. The SMC 3.5 seems to stand up extremely well against its faster sisters. Their only virtue is the extra speed and, considering the greater cost, at wide apertures the IQ isn't that great in your examples. My lens is the Super-Tak version and the man who sold it to me mentioned later (on another forum) that he'd never really felt comfortable with it, so I think it will be up for sale shortly.

Of all my 35s I love the Flek the best, followed by the Mir-24, but I particularly want a Tak to accompany my Pentax cameras. I'll look out for a SMC 3.5 but if I see a larger 2/35 Super-Tak going cheap I might give it a try. Thanks again.

If you set auto white balance, then wouldn't the 400D compensate for slight tints?

I think the better option would be to try 2 lenses side by side using the same WB setting.

Expired film!! OK. Not ill lens, good for you.

I like the Pic n° 5, so much. The golden tone of the Tak do a great image.

Rino.

I tried it, using Daylight WB not Auto. Strange thing, in Av mode the camera seems to want to use a slightly slower shutter speed for the Tak and overexpose a little compared to the Flek. In manual mode using the same speed and aperture, the exposures are similar although the indicator is showing underexposure for the Tak. The colours are as before, the Tak is cooler and the Av mode pics look a little faded.

But remember I want to use this lens mainly for film. I'll give it another shot with a different film, but I don't have a lot of confidence in it.

Thanks for the ideas.
