You have a BMCC and also looking for a C100? Why? Just curious...
What's a used C100?![]()
You know... those. Yep, don't see them often.
That's weird. My Tamron 17-50 F2.8 lens works well with the C100.
Canon needs to accept that the reality is that not everyone can afford or wants to use Canon glass. In fact many owners use "off brands", even on this forum. Blackmagic initially dismissed complaints about the Tokina 11-16 and other lenses not reaching infinity focus on their BMCC EF mount and after an onslaught of complaints recalled the units and shimmed the mounts. Also, would Canon's logic also extend to a lens like Zeiss compact prime? Well, they're around $5000 -- what if they didn't work on the cinema series cameras?... Beyond any of this is the disinterested and generally dismissive attitude Canon displayed towards my friend... BTW Canon did test one of the Tamron lenses on another C100 and it controlled aperture.I'm sorry but using third party glass is a risk you take. Canon tested the camera with genuine glass and it was working without a problem. Not Canon's fault and they shouldn't have to test it with anything else than Canon glass. A third party lens might work with one camera and not the other. I've had issues like that before with other cameras and it was the third party lens that didn't work quite well.
Tamron, Rokinon, Sigma etc. do test their lenses the best they can with Canon cameras. The problem is that Canon doesn't publish their specs, so these companies are basically reverse engineering Canon mounts/lenses. IMHO it would be mutually beneficial for manufacturers to share there specs because the reality is that there are some people out there that can afford a Canon body but not genuine glass and I think companies like Canon would prefer to sell you a body rather than nothing at all... And BTW I'm not naive -- I know that companies spend a lot of money on R & D and don't generally share their technology.I don't think that Canon should be responsable for this. Tamron should test the lens with the camera, not the other way around.
Canon is not going to give all their specs to Nikon either. They're really under no obligation to do it, and I can't blame them. Unfortunately the result is that sometimes things like this happen with third party products. I hate to say it, but the Canon tech was right if the camera was performing correctly with the canon glass. Canon isn't obligated to make their cameras work with anyone else's gear.Tamron, Rokinon, Sigma etc. do test their lenses the best they can with Canon cameras.
