Olympus, mind you, has the ONLY DSLR system with a sensor dust removal system.
So, IMHO, both Canon & Nikon suck!!!!!
(get on the ball you guys) |

Canon's EOS system was implemented in 1987 (. And the EF mount was the move from mechanical to electrical. A very good move IMHO. This was the 4th generation of lenses, replacing the FD lense series which was implemented in 1971. (FD was the 3rd generation, following Canon's 2nd generation FL lenses. Which used artificially made flourite and replaced the prior RL lenses).
Of note... "The EF mount, with an internal diameter of 54mm (external diameter of 65mm), has the largest clear aperture of any lens system used with a 35mm SLR camera. The large aperture EF mount made possible the brightest lens in the world designed for a 35mm SLR camera, the "EF50mm f/1.0L USM" lens."
"Although Canon does not endorse (and in fact warns against) the use of third-party lenses and adapters, the EF lens mount is ideal for the use of adapters, due to its large diameter and the relatively short flange-to-film distance of 44.0 mm[1]. It is thus possible to mount lenses using the Nikon F mount, Olympus OM, Leica R and universal M42 lens mounts (among others) by the use of a simple mechanical adapter."
So, it's not like I can't use an old FD lense. I can buy an adaptor and still utilize the older mounted lenses. I mean, hey, if I had a 600mm FD, it's not dead glass. And since the FD series was not autofocus, it's not like I've lost the autofocus ability. Furthermore, I can mount quite a few other lenses onto it with adapters.
In many ways, it's very much akin to the Russian's strategy of always using ammunition that was slightly larger than ours. This way, they could use our ammunition if they ran out. But we could not take advantage of theirs.
Is it perfect, naw...you've got to have a touch more skill and know how to meter and adjust your aperature accordingly. *shrug*
1959 Nikon implemented the F-mount. Yes, you can use any Nikon F series SLR lens from then till now on a Nikon camera. However, some functionality will be lost when using older lenses. It might be nice to mount a brand new Nikkor lens on an original F-1 camera. But I see that seldom happening.
So I really don't think that's too big of an issue.
Will Canon change their mount in the future? possibly...but if they do, I imagine they will simply add an advanced communication port and I doubt the actual mount will change. The mount was altered because many users of Canon did not like the mounting mechanism of the FD system (and the EF system mounts much more easily) and because they wanted a wider mount to allow for increased light. Doing so allowed them to offer the 50mm f/1.0

I would appreciate it if you could find me these two adapters - Canon FD and Pentax K to EOS........ no $1000 custom jobs either. They must not deface my camera and function. I'll pay you 25 bucks. |

I don't know where you were reading it, and perhaps they were talking about P&S models.
But Canon's current DSLRs are known for being a generation ahead of everyone else in low-noise for ISO shots. In fact, in most reviews Canon's XT/20D's 1600 ISO usually has less noise than the competitions 800 ISO settings. |
This was in Pop Photo's 2006 Digital Imaging Guide (a special edition sort of thing). Most of the popular dSLRs got a page that includes some general discussion and for many a box with some ratings they refer to as "Certefied Test Results". I'm not about to read through the articles again this late at night, but from those "Certefied Test Results" boxes, the noise ratings are as follows:
Canon Rebel XT: Very Low at ISO 100, low at ISO 200, moderately low at ISO 400, moderate at ISO 800, unacceptable at ISO 1600
Nikon D70s: Very low at ISO 200-400, low at ISO 800, moderate at ISO 1600
Nikon D50: Extremely low at ISO 200-400, very low at ISO 800, low at ISO 1600
Pentax *ist DL: Very low at ISO 200, low at ISO 400-800, moderately low at ISO 1600, moderate at ISO 3200 |
