Me for one didn't by the A7r for e-mount lenses per se. So far the 10-18 is fine, it came with the 28-70 and its modest. I'm waiting on the 70-200 F4 not nec for the A7r but for the A6000 when it gets here-really want to see what that combo will do with BIF/MOs and autofocus. Bottom line for unless I'm shooting in the bird studio out back is weight. The landscape A7r is for me solely and landscape camera. Yeah I'm sure it can go more but that was/is my intent.

Toddlers are a challenge no matter what the camera/lens setup. Here's a shot I took a couple of days ago of one of my great grandsons. I used my a7r and Sony 24-70 lens on auto focus. Not too bad considering the low light. Even shooting at an iso of 1250, the shutter speed was only 1/80th.

gear question, what strap will you recommend for the A7r, the Sony strap works okay but I am used to using Black Rapid strap on the 5D2. What are you using and why do you like it.

I got the Peak Design "Leash" last week and so far, I'm very pleased with it.

I should add why I like it. It utilizes quick releases for the strap that work very well. The leash comes with four quick release 'tabs'. I have mine set up so one release is on the left strap connector of the camera and another release on the plate on the bottom of the camera. This allows the camera to hang by my right side comfortably with the lens facing down. The video on their website demonstrate how the leash works better than I can describe it.

I also got the "capture pro camera clip" with the mini plate but I haven't had a chance to use it other than to try it out at home.

I am not a professional and it can be quite a struggle to get my 7D to focus on my constantly moving toddlers, even with AF and IS. I would love a A7R but MF would be impractical for me :eek:

you need to try the focus peaking..... helps a lot, and much different from pure optical focus, which is harder to achieve.

while true, keep in mind that brand new system.

also

1) you can use normal E mount lenses, camera will automatically crop to 12mp (a7) or 16mp (a7r), thats not bad with A7r, only 2mp less than most canon bodies, and you still get better color and more dynamic range.

2) you can use sony adapter with phase detect and use all a mount lenses.

3) you can use metabones adapter and use all canon lenses

4) because of short flange distance you can use pretty much every vintage lens you can find with ultra easy focus peaking.

so yes, while the native glass is limited, considering the caemra is only about 4 months old. what did you expect?
but its certainly not limited to usable lenses.

Ok hang with me as I ask elementary questions. I'm really searching for a system that will fit me but I'm very unfamiliar with sony.

"E mount lenses" Vs what exactly? The "alpha" lenses?

"Sony adaptor with phase detect" So there is another adaptor besides the Metabones?

btw...for birds in flight I understand that the a77 smashes my 7D. yes?

there's two methods, a box with 10x magnification, and the outlining

you can do it on your canon with magic lantern, with an EVF, this should be built in.

The NEX cameras and A7 twins use what Sony calls E mount (just as Canon EOS cameras use EF).

Adaptors: Metabones are just one of the many manufacturer's of mount adaptors. There is a larger range of lenses in Sony's A mount which will cover a FF sensor (most E mount lenses were designed for the APS-C NEX bodies so won't cover the APS sensors). Sony has 4 different adaptors for A mount lenses to the E mount - these provide varying electronic control of these lenses dependant on the adaptor and lens.

Can't help with the A77 sorry

Ahh...so the Metabone is what is used to allow Canon lenses on the E mount body. But a Sony A to E mount adapter would be needed to allow Sony A to Sony E. hmmm...

This two part article might help clear the air on compatible lenses and converters for Sony's a7/a7r cameras.

http://briansmith.com …-a7r-lens-mount-adapters/ (external link)

"Sony’s A7 and A7R are the only cameras that allow you to use virtually every make of 35mm lenses with the full angle of view for which those lenses were designed."
