    The sad thing is that the whole camera system among major manufacturers are going rapidly to mirrorless. Photogs don't want to lug heavy artillery to the range anymore. They want small and compact with great resolution. That's the way it's heading. Rapidly. The old tank lenses and bodies will depreciate rapidly.

    Ooooooo you sure got me.


    I don't feel the need to give a thought-out response to an irrelevant argument.

    I only wanted to point out its irrelevance.

    Also, look up the word "irony."

    Except if you want f/2.8 you'll get a tank lens
    If you want f/2.8 with VR and the bells and whistles (more technology) it's going to be larger.
    If you want f/2.8 manual focus then it loses all that technology and is quite a bit smaller and lighter.
    f/4 .. smaller and lighter yet
    variable aperture .. smaller and lighter yet
    variable and manual focusing .. smaller and lighter even more.

    it all depends upon what you want.

    The bodies are of course smaller the dslrs.

    It just comes down to using the specific equipment that you need for the photography that you need.
    once Mirrorless has all the bell and whistles of the DSLRs but smaller and lighter (and less money) then there's going to be a big switchover.

    But then who knows

    Yes I have. Two of the first three lenses I had for my Canon were a Takumar 55mm and an Auto-Chinon 135mm.

    However, I did not have a proper focus screen and it was more difficult than it's worth.

    And it may be much easier to manual focus on the A7 than the Canon, but that doesn't mean it's easy.

    The fact that manual focus on the A7 is easy to you doesn't help out the people who don't have that skillset.

    It makes more sense (to me) to just buy a different camera as opposed to buying the A7 and learning an entirely different, specialized skillset, in order to workaround the camera's autofocus issues.

    24 megapixels on full-frame is a nice capture size, and allows high-volume shooting without an incredible download and storage hassle. I shot a HUGE set of 1,055 raw 24-megapixel images yesterday on 28 gigabytes of memory. You get fairly big pixels on FF, compared to the same number crammed onto a smaller sensor, so you get a bit better High ISO performance capability, and the real advantage is the way the lens focal lengths work on the 24x36 sized capture medium; a 50 is a normal lens, and 85mm is a USABLE telephoto, even inside of a living room! You don't have to be 35 feet back to successfully deploy the 85mm for vertically-framed, full-length, standing portraits! I hope you enjoy the new rig!

    Real, old-school manual focus lenses have slower, more-precise, and usually mechanically superb focusing ring control; MOST autofocus lenses have an incredibly loose, sloppy, non-dampened focus ring movement, which goes like this: Infinity, then in 10 degrees of rotation, 3 meters! it makes it damned near IMPOSSIBLE to accurately and repeatedly focus on stuff in the all-important ranges between infinity and over 10 feet!!!! ACK! Sure, you can hit focus, but not always consistently, because the mechanics are so loosey-goosey. But...use a precision-built, manual-focus designed lens, and the focusing distances are spread out over up to 240 degrees of rotation, so its EASY to get the focus right, time after time!

    Congrats on the new camera. I'm pretty much sold on the idea of the Sony A7R to be used with adapted lenses... in particular my M-mount lenses and perhaps my collection of Pentax/Takumar. Just waiting for the right price.

    My only issue with a FF mirror-less cameras is that the lenses themselves haven't really gotten any smaller. I think its simply a physical limitation from the size of the image circle needed for a FF sensor. I am also a MFT shooter and I find that system established the ideal balance between performance and size. There is a huge difference in size between the Sony A7# + 70-200 f/4 + 24-70 f/4 and the OMD EM5 + 35-100 f/2.8 + 12-35 f/2.8. So with that size difference and "enough" performance delivered, I'm content. Of course, everyone has their own notion of "ideal balance".

    On the other hand, I found that adapting lenses designed for FF on a sub-sized sensor results in an experience that is less than interesting to me. I still love shooting the M9 BUT I have to say Sony offers an interesting proposition; small body with small high quality FF lenses. With that the A7R has my interest.... and I am willing to explore (yes I have heard of corner issues). Looking forward to trying it out..

    Autofocus has made many lenses a LOT larger than their manual focus predecessors. From left, 85mm f/1.4D, 85mm f/1.8 AF-S G, and 85mm f/2 Ai-S Nikkor lenses.

    [​IMG]
    [ DSC_4931_85mm trio.jpg photo - Derrel photos at pbase.com ] The 85mm f/2 Ai-S is about the same size as the 35mm f/2 Ai-S is; they in fact appear to be almost identical in size, almost as if they were built on the same barrel and helicoid systems! The 85mm f/2 (far right lens) has a VERY high "telephoto factor" compared against the newer 85mm autofocusing lenses, which are significantly longer in physical length. The 85mm f/2 AI-S is about the size of a 50mm f/1.4 lens. It is VERY compact. Super-easy to carry, and affordable.

    Nikon's 105mm f/2.5 Ai-S is a splendid lens in terms of optics and mechanical smoothness, and focuses amazingly well. The one-oh-five-two-five might be one of the easiest lenses to focus by hand-and-eye. It's almost perfectly engineered!
