![]() ![]() In addition, FD mount flange is long, and the new EF has one of the shortest flange distance in any full frame DSLR, that makes EF one of the most adaptable DSLR on the market. Back in the days switching to electronic and auto-focus, Canon ditched the old FD design (thank god) because FD mount is basically shit, reversed the bayonet, a lot of moving mechanism on the lens and its a pain in the ass to disassemble and repair (personally I have a lot of problem doing that). Popular lens mount Canon DSLR, EF/EF-S, EF-MĬanon has one of the world’s largest market share in DSLR. ![]() use of electronics to replace certain mechanical components to improve on speed, ease of use and possible reduction in overall cost.ģ) Though there’s no data on actual comparison of mechanical/electrical failure, coming from general mechanical characteristics- Number of parts (less the better), number of moving parts (less the better). I am stating the assumptions here.ġ) Priority in production engineering, number of flips for machining that can contribute in production time and cost.Ģ) Second priority in engineering simplicity in packaging. Thanks for some first feedback on the bias on electronics and failure rate. Post introduction and assumption in engineering I will skip the detail on the sensor size and focal length in terms of adaptability. You can see some popular lens mount and their flange distance here: Mount In general, the shorter the flange, more lenses they can use, but not necessarily better, which I will explain later on Sony’s E-mount.Īs illustrated above. To put it simply, the brands that chose shorter flange distance will gain accessibility of third party designed adapters to fit other legacy lenses (other factors includes the thickness of the adapter, material, design, and even lens mount diameter). I maybe wrong on some details, so please correct me if you must! Introduction, flange distance, adaptability of SLR, DSLR and mirrorless.īefore I compare the brands and engineering, I have to explain the flange distance for the benefits for those who are not familiar. Therefore I would like to share my views purely on the engineering aspect with my limited engineering knowledge and a little background, hoped to clear the clouds and differences once and for all, and maybe this can help you decide on your next camera. I still remember the days when I first started photography, I asked my friends the most commonly asked question, ‘what camera should I buy?’ Everybody seems to have their own biased opinions about the brands, some called themselves the canon fan boys, nikonians, pentaxian and so on.
