Nikkor Posted August 10, 2013 Share Posted August 10, 2013 Hello, I just got a Sankor 16c off ebay (150€, 80€ would have been an ok deal but I didn't want to wait more). I need some advise about which lens to use it with. I read a lot about helios 44-2, but I have found a nice zuiko om 50 1.8 which looks like is going to have the lens a lot closer. Any advice? I want to use it on an canon 50d with ml raw,etc... Also I'm wondering ,given that the sankor 16c seems to be huge, if connecting it with a clamp won't break the filter thread, and therefore making the sankor fall down,etc...

Tim McC Posted August 10, 2013 Share Posted August 10, 2013 I've used the sankor 16c on a number of taking lenses and never broke any filter threads. Unless you're running down the street with it, I wouldn't worry. Which clamp are you using? Quote Link to comment Share on other sites More sharing options...
Nikkor Posted August 10, 2013 Author Share Posted August 10, 2013 I won the auction this morning so I still don't have any clamp, there are some cheaper ones but I guess I should buy a redstan, right? ^^ Any suggestions are welcome. Regarding the taking lenses, since you have tried a few, what do you think would not vignette on a 50D APS-C. The zuiko om 50 1.8 looks nice and small, and it seems like I can get the sankor pretty close. Thank you for your help! Quote Link to comment Share on other sites More sharing options...
Nikkor Posted August 10, 2013 Author Share Posted August 10, 2013 I just noticed, that the lens is not a sankor 16c, as the seller said, but a 16d (it's completle black and it does not say 16c anywhere, and it's different in shape). I found out that the d is bigger and heavier and it has a bigger back thread. But I didn't find anything about focus distance and general quality when compared to the 16C, any idea?

Tito Ferradans Posted August 10, 2013 Share Posted August 10, 2013 It's pretty much the same, but bigger optics (better), and stronger construction (better too). Redstan HAS a custom clamp for it, you can check some more info here: https://drive.google.com/?pli=1&authuser=0#folders/0BzVcUB-5ReiZajVncE9rYU9heDQ or, if you don't feel like looking up through them all, the Sankor 16-D is here: https://docs.google.com/document/d/16zeZOt79LDBFVVQ5nCVfNqPGUkXLOu1GtVVkh6SoOvs It SHOULD work at the edge of vignetting with a 50mm on APS-C. :P Quote Link to comment Share on other sites More sharing options...
Nikkor Posted August 10, 2013 Author Share Posted August 10, 2013 Oh man I got it all wrong, it's actually a 16c. So I got back to the original question, what would be a nice taking lens, I know about the helios 44-2, It would be nice if someone had some more experience with other lenses (the zuiko for example) thanks for the help!

Tim McC Posted August 12, 2013 Share Posted August 12, 2013 Yes, I'd go with the redstan clamp over the Vid Atlantic, having used both with the Sankor 16c. Your 50mm may have some slight vignetting at the corners, which you might find to be a charming effect or may cut off entirely if you crop to get down to a 2.35:1 ratio. You're definitely not going to get a sharp image wide open, so be prepared to stop it down. f/4 is a good place to start. BTW, the more you stop down, the less vignetting you should see...

Nikkor Posted August 12, 2013 Author Share Posted August 12, 2013 thank you guys! I've been watching some videos (still don't have the sankor) and there is a "strange vignette", when you face the sun a white halo appears out of nowhere. I guess this is a know problem and I was wondering where it comes from. Quote Link to comment Share on other sites More sharing options...
Gábor Ember Posted August 12, 2013 Share Posted August 12, 2013 The white vignette is the reflection off of the inner parts of the anamorphic (inner glass or inner tube) Quote Link to comment Share on other sites More sharing options...
Tim McC Posted August 13, 2013 Share Posted August 13, 2013 Actually, I think it's the opposite of this... o.O Is it? Maybe I'm remembering it wrong. Either way, it shouldn't be a big deal paired with a 50mm on the aps-c sensor. Quote Link to comment Share on other sites More sharing options...

QuickHitRecord Posted August 14, 2013 Share Posted August 14, 2013 Is it? Maybe I'm remembering it wrong. Either way, it shouldn't be a big deal paired with a 50mm on the aps-c sensor. It's a mechanical vignette, like in the article linked by tosvus: Oftentimes when I am using a lens combination that is right on the edge, I can literally see the inner barrel of my anamorphic past f/5.6 or f/8.
