DreamingBMCC Posted February 16, 2014 Share Posted February 16, 2014 Hello, today I bought a 17 mm prime lens RMC Tokina on a yard sale for 6 €. The seller haggled really hard and did not want to settle for 5 :). I do not know what mount the lens has and neither did the owner, but for 6 € I'd use it as a paper weight if I cannot adapt it haha :) Pic of the mount: Can you guys help me, what mount is this? Cheers! Quote Link to comment Share on other sites More sharing options...

Quirky Posted February 16, 2014 Share Posted February 16, 2014 That looks quite a bit like a Minolta MD mount, or a Leica R mount, but I believe those two had only one lever, instead of two. Right now I have no lens within my reach to make sure. But if I had to guess, and if Nikon F, C/Y and Konika AR are ruled out, I'd guess it's a Minolta MD mount. At least it looks very similar. You could also try and see which mounts Tokina has made that particular lens for, and then rule out all but one or two most likely ones. I believe the two levers inside the mount are a good tell-tale sign when ruling out the possibilities. Quote Link to comment Share on other sites More sharing options...
DreamingBMCC Posted February 16, 2014 Author Share Posted February 16, 2014 It is not Leica R, and I do not think it is Minolta MD either. It says N/AI on the lens mount, and google thinks that is a Nikon mount. But it does not look any familiar to any Nikon I know. Quote Link to comment Share on other sites More sharing options...
Quirky Posted February 16, 2014 Share Posted February 16, 2014 Well, it does indeed look quite like an old Nikon F or AI, and that was my first guess when I saw the photo. But I dropped that guess, because Andy seemed to be sure it's not Nikon in his comment above. I hope you can find someone with a Nikon body to confirm it. I can't, because the Quirky household is a 100% Nikkor-free zone at the moment. :) Quote Link to comment Share on other sites More sharing options...
DreamingBMCC Posted February 17, 2014 Author Share Posted February 17, 2014 I just had a though. The image circle seems rather small vor me to cover a 35 mm frame. Is that usually the case for wider lenses? Quote Link to comment Share on other sites More sharing options...
dahlfors Posted February 17, 2014 Share Posted February 17, 2014 As a Nikon shooter, I wouldn't actually rule out Nikon. Granted, it doesn't look like most of the Nikon F mount lenses I've used (which all vary, depending on AI-S, AI, AF-S etc), but it's not too far off from what an AI-S 105mm f/2.5 looks like: '> It might fit. The RMC Tokina 17mm was made for Nikon mount at least. DreamingBMCC makes a valid point though - the rear element circle seems very small. But perhaps that's a part of the lens design. EDIT: This seems to be the same lens, for 35mm Pentax, so the small rear image circle seems to be part of the lens design: http://www.pentaxforums.com/forums/36-sold-items/241488-sale-sold-tokina-17mm-rmc-f-3-5-lens.html - So, I'd try to see if it fits on a Nikon - without forcing it in...

dahlfors Posted February 17, 2014 Share Posted February 17, 2014 Googled. Found this image from an expired online auction of RMC Tokina 17mm Nikon mount: '> To use this lens with metering on a Nikon body, you need D7000/D7100 or higher. Without metering it will function on most Nikons in manual exposure mode. Quote Link to comment Share on other sites More sharing options...
dahlfors Posted February 17, 2014 Share Posted February 17, 2014 There's a lens comparison of that RMC Tokina with a few other Nikkors: http://www.kenrockwell.com/tech/comparisons/2010-08-10-17mm-sharpness/ That lens is very well worth 6 euro. Seems to be one of the better wide prime lenses for Nikon mount, although Nikon's wide zooms are better. Quote Link to comment Share on other sites More sharing options...
DreamingBMCC Posted February 21, 2014 Author Share Posted February 21, 2014 It is a Nikon. I bought an adapter F mount to Canon EF and it fits my EOS now. 30€ total, I am quite happy. I played a bit with it and it is much sharper than my 18-135 @18 mm in any aperture setting. This would also make a nice standard lens on the BMPCC plus with a Nikon to BMPCC speedbooster I could have two different lenses in one. A follow up questions regarding that, that is slightly of topic and requires a bit of an explanation first. I thought I might get a BMPCC soon but I am a bit on a budget so the 17mm Nikon lens would have to do first with a F mount to Micro 3/4 adapter. In the long run, I wanna use the new Sigma 18-35 1.8 everybody is so psyched about at the moment on the BMPCC. So here the question: Can I use the Sigma with the Nikon mount on the BMPCC with electronic aperture and focal control? The Tokina is all manual, so I will not be able to derive any information from that. Quote Link to comment Share on other sites More sharing options...
