Hi guys, it's been awhile Smile
I was wondering if you could identify this tokina lens... I know it's RMC 28/2.8 for AR mount, but it looks very different than a "real" RMC tokina

Another version, of course. (Who would fake it?!) Perhaps the "real" RMC Tokinas are fakes! Laughing

Consider the number of 1:2.8/28 versions by Soligor -- this tells me there was a lot of competition among manufacturers, each adopting the latest design -- during this period (computer design), many new designs appeared...

that's obvious Smile
what about image quality?
I have the green labeled RMC Tokina 28/2.8, very sharp lens at wide open (corners blurred) but the aperture is stuck wide open and local repairman wants 20€ for cleaning ... you get my point Smile

...or would a hexanon 28/3.5 be a better choice?
although I've had one in mint condition but optics were decentered and there was some fungus which didn't came off after cleaning....

Yes, the Hexanon would be a much better choice especially the 7 elements in 7 groups version (the second down on the page link below) which is a superb lens.

+1

Out of maybe twenty 28mm lenses I have owned, the best three were the 7e Hexanon, the contemporary 7e Rokkor and the Mamiya SX 2.8/28 which I think is also 7 elements.

I've had 5 or 6 copies of the Tokina and while it's a good lens, it's a step below the Hexanon, Rokkor and Mamiya SX.

I've personally yet to see a Tokina lens that isn't a Tokina lens. It's rather Tokina, a lens maker, that made lenses for just about everybody at one time or another, than the other way around. This is a legit RMC, but it's an earlier type. The RMC indication in green (which I suppose is what you mean by "real") date from the late 70s and the 80s. The one you have preceded them and is from the first half of the 70s by the looks of it.
It's a very decent lens, but as DigiChromeEd and iangreenhalgh1 already mentioned, the 7/6 Hexanon 28/3.5 is much better indeed. If you're considering one, I'd suggest the the one with the rubber covered focusing ring (1974-1978), as that one will have somewhat better coatings than the solid metal focusing ring one (1970-74) and the one with the aluminum ring (1965-1970).

I used to have an older version of the 2.8/35 Tokina, it had a similar design as yours. It had very low contrast on a digital camera.
One of my favorite lenses is the newer RMC 2.8/28 with the green labeling. I love that a lot on digital.

Some samples here: https://www.flickr.com/photos/chantalrene/sets/72157630430002884/

I have the green labeled RMC tokina and even at wide open it's extremely sharp in the center and has very high contrast and nice colors... corners are blurred on FF and get better when stopped down (opening the lens and physically moving the blades)
but the cleaning costs the same as another "green" tokina rmc 28/2.8

it's quite a common problem with the RMC 28mm, I had one and it's quite easy to clean yourself.

here a youtube clip on it:

A very nice lens to use I must say, I was sad when I sold it and strangely havn't come across another one here.

Early design - big front glass M42 2.8/28mm Tokina = Sears = Auto Mamiya / Sekor = Rikenon = Soligor serial 17.

Please comapre the photos: http://aflenses.ru/id/31776
Mamiya / Sekor Auto described as 7 elements: http://allphotolenses.com/lenses/item/c_2028.html

So it makes little sense to favor Mamiya over Tokina. And we are talking old Tokina. RMC compact design is even better lens in all terms.
