Next thing they will add OCR for hieroglyphs so you know what is in the photo you took in Egypt.

Don't laugh. I know a guy that shoots a Super Tak 50/1.4 on his 5D and gets really good results. And I use a SMC Tak 50/1.4 on a F-mount camera for close up still work on occasion and that lens performs really good.

Maybe all of those old ones are community supplied.

That makes sense.

The Tak 50/1.4's don't need a profile because they are perfect in every way

Hm, I do wonder, though, if the Pentax and Tamron will be exactly alike. Can anyone read the parameters of the corrections and compare them? The Pentax version will have different lens coatings (or so we were told?), so it is possible that things like CA will be slightly different. Or are the different coatings not really a significant difference, these days?

Either way its good to see the lens profile. Either Adobe is keeping an eye out for Pentax (something that wasn't happening so far), or Pentax is prudent enough to send them data ahead of time. Good job either way

I don't think so, because then why don't they have profiles for lenses like the Samyang primes?

The optic formoula for most 50mm lenses is the same, and provided they multicoated and from reputable manufacturer they should be almost perfect at by f/5.6 to f/8, or at least you will need 200% magnification to see the difference at a computer screen. I just like joking with vintage stuff, I don't think they are inferior, I just don't like the mojo thing going around them. I use old stuff when it suits me, but I have seen some really weird prices on manual lenses, other than macro, which I cannot really accept as sensible.

I think they were using the Tak 50 profile to calibrate Lightroom, not the other way around. Obviously the lens is perfect.

i just find it funny to have optical corrections for a manual focus film lens. I just put this 40 year old lens on my camera, but hey LR I want you to remove all the distortions and vignetting so that you can make it look like I took it with Zeiss Otus.

I tried making one. It's a total pain in the behind.

I'm wondering how this is corrected, for distortion only? There would't be a way to tell what aperture was used, so vignetting can't be corrected with the profile. I'm not sure what other "magic" happens in LR, if there is some aberrations taken care of as well, but those should be dependent on aperture as well...

**jatrax** · 10-08-2015, 11:26 AM

No idea. But i dont understand what the aperture has to do with correcting for vignetting? Not that i understand most of this stuff anyway.

A lens will have the most vignetting at maxium aperture, usually when stopping down just a few stops it will almost dissapear. This is different from lens to lens though, that's why the aperture value would be needed...

Something like this for different apertures.

Have a look over at the "Wanted: Adobe Lens Profiles" thread.
