I have now owned the Sony A77 for a couple of months and I must say I am very impressed. There was teething problems on release but Sony have listened and a few firmware updates later we have a great camera. I am not going to go into all the details that you have already read about, you know it's 24m pixels give superb resolution and it is lightening fast. The view finder is amazing with info, spirit level and image review all possible without removing the camera from your eye. The sweep panorama function I thought like most others would be gimmick that would never be used but the 30inx7in jpgs are great and can be done where you would struggle to create a 2 shot stitch for example from a moving boat. I have used my camera in both the studio and on location in some testing weather conditions and it performed flawlessly every time. One more thing for the people that shoot jpeg's DRO (dynamic range optimiser) when used can save so many images by reducing blown highlights or keeping detail in deep shadows, it can make some images a little flat but a quick levels adjustment soon sorts that.
So now the bad bits, there is only one and its battery time, one battery will cover you for most shoots but to be on the safe side I purchased a spare battery. I might add a grip but I'm not keen on the extra bulk but I don't want to worry about having to change batteries during a wedding.
So all in I would highly recommend the Sony A77.
Welcome to my blog. My photography is on a tight budget like so many others out there, but through this blog I hope to show that great photographs can be achieved by all.
