              It's one slot but you can put 2 different types of memory cards into it.

              I've seen the comparison between 7D and A77 photo's, I'm afraid to say that even without like for like lenses the A77 stomps all over the 7D IQ wise, lens quantity always makes me laugh, when you put Minolta lenses into the equation there is very little difference, the only major and important difference is that Minolta lenses are cheap, e.g I bought the 70-210 F4 for only £53, delivered. I have a mate who has a 7d and a very old 1d, both have expensive canon lenses fitted, he takes football photo's, as do I, except I only take an A77 and a Minolta 135mm f2.8 lens, the comparison between our shots would surprise pro canon users and settle this dispute of which is best, instantly. Ironically the A77 is getting on now and yet continues to trample on the much dearer 7D and far inferior but similarly priced 60D. Not bad for a manufacturer who's been making SLR's a fraction of the time Canon has been ;-) .

              just use 550d camera and check the result

              Sony A77 is also weather sealed. Rapid fire (burst mode) is faster on the A77 a max 12fps.
              Sneaky_Pete (7:50 PM, September 25, 2012)
              The Canon 7D does not shoot at 25fps, it shoots at a max of 8fps as per the Canon website. It has a max burst of 25 shots when in RAW. And with that the Sony A77 should move ahead in points.

              Sony wins hands down...the 7D can barely beat the A57 let alone the A77

              You also get to use all the  Konica Minolto & Minolta legacy gear too which you can buy a bargain prices
              Pkepron (6:19 PM, February 23, 2012)
              Having trouble making up my mind between these two.  Both are great cameras, but it seems the Sony scores higher and is more camera for the buck.  Unfortunately the A77 is hard to find and you are basically stuck to using all Sony gear.  I would really like to rent the two for a few days.  Unfortunately no one in Montreal rents the Sony. :(  I would also have to sell or trade all of my present Canon gear in order to get the Sony (Not that that matters).  Decisions, Decisions!  Hey Sony if you need a field tester I'm available! :)

              Depends on what you're using it for. EVF is very handy with the level gauge, previewing the ISO and previewing the look of the shots before you take it (thanks to the preview button). The advantages of it for me are far better then having an OVF, especially when all the OVF does is show you what it looks like from the mirror, not what you get on the sensor.

              The Sony HAS two slots fpor memory cards: one for SD-Cards and one for Memory Sticks
              APR (1:46 AM, January 18, 2012)
              Error: the Sony does NOT have two memory slots, just one.

              If you have other suggestions I would love to hear them, trying to stay around 2000, found 7d with 2 lenses cheaper than sony.
              Casey (11:17 PM, January 04, 2012)
              Based on these comparisons, sony is a better buy, hands down. Showing us more of the 3rd gen type camera, however I'm an everyday shooter and would rather sacrifice some of these positives of a longer life.... Very torn of which to buy. Already have canon lenses :( is there anyway to use them on this sony? Thanks for you're nice helpful comments...

              I woould actually READ the whole of the DPREVIEW on the canon 7D instead of the fingertip   handshake  DXO give it in the comments above!!
              DXO are a little biased imho in favor of the sony!!!
              Neopren (10:23 PM, November 16, 2011)
              ...Also,I'd be concerned as to how many people have actually  handled the SLT 77,before voting,EVF NOT good for Professional or even semi pro shooting,most prefer OVF!!
              Neopren (10:18 PM, November 16, 2011)
              Slt has only one storage slot NOT two!!
              Also you can get headaches using EVF  on SLT 77!!

              viewfinder magnifications are incorrect. 7d has 1.0x magnification and a77 has 1.1x magnification also eye relif is an advantage to the Sony where you don't have to squish your eye into the viewfinder.
              Squash (7:01 PM, October 01, 2011)
              I'll see if I can dig up Canon's own links. The 7D is weather resistant, but not sealed to the extent of the Canon 1D series or Pentax line (or Sony/Nikon pro line).

              It's good, but not actually weathersealed, with major gaps in the sealing at the shutter and pop-up flash.
              Derkjlerl (10:36 PM, September 13, 2011)
              The 7D IS in fact weather sealed. If you could update that, it would be greatly appreciated.

              Hi Ollder, our mistake, when the camera was first announced it was hard to find accurate information, you're definitely right, it supports a max iso of 16,000, we'll have our specs updated shortly.
              Ollder (8:41 AM, September 13, 2011)
              HEY! Where did you find the maximum light sensitivy as 12800 for Sony a77 ???  In announced specs it is 16000. (Not a big deal as a property but as a mark of your reliability)
