... as the adapter increases the distance between the sensor and the lens by ~10mm, does this effectively make my 50mm lens a ~60mm lens? Or am I just misunderstanding things? You're misunderstanding things. The Minolta MD/MC registration distance (or flange focal distance)--that is, the distance from the mount flange to the sensor, is 43.5mm. If the ...

The answers you've gotten are correct, a standard/correct adapter does not change the focal length. It is worth noting however that there are some adapters called Speed Boosters which are designed to do exactly that. They counteract most of the "crop factor" caused by the smaller sensor. They aren't cheap, but it's always good to know your options. For ...

It's not just the weight of the camera that's a concern, but the torque that it will apply to the mounting ring on the lens (and in the camera, of course). Torque is turning force, and it's calculated by multiplying force (weight, in this case) by distance from the center of rotation. So, if we guess that your camera is 4" deep from the mount to the back of ...

The 1D Mark II was 55.5 oz. The 5D Mark III + BG-E11 grip + 2 LP-E6N batteries is about 59 oz. The heaviest flash Canon has sold in the recent past is the 600EX-RT which is 18.5 oz with batteries installed. The WFT-E8A is another 1.35 oz. Add that up and you're at 79 oz. which is about 17 oz. less than a 6 pound CCD camera. The EF mount should be able to ...

I don't have the answer for you but the answer is maybe obvious : if it were a classic mechanical problem, I would say that the lens capacity shouldn't exceed the capacity of the body (using no lens collar): If you body can support a 2 kg lens on the body mount, then the same weight is supported by the lens mount ; If your lens comes with a collar for your ...

I have K&F Concept Lens Mount Adapter: http://www.amazon.com/Concept-Adapter-Pentax-E-Mount-NEX-VG10/dp/B00LECYTL4?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s01 It works perfectly and I like that the one I have for Nikon F Mount is from a different company (Kiwifoto) so its easy for me to identify which is which. It is all ...
