John,
It is a big financial decision to jump ship but I will certainly will not be buying any more Sony mount lenses.
I agree, but I would not throw out the baby with the bath water just yet...
While it is unfortunate and in my opinion an important design flaw, the A55 I do believe is one of the first cameras of the future...I strongly think that cameras with mirrors will soon be something of the past and we will have mirrorless cameras. The A55, this is my understanding is apart from the studio issue (and there are ways around it) a very capable camera and frankly I do think most cameras have their short comings in one area or the other. Just have a look at the Canikon forums...
Sony has now overtaken Nikon in camera sales in the UK and while the camera sector might have been not the most important sector for Sony in the past, I do think they will direct more resources towards this sector in the future, which is good for the development of future cameras and for their market share. Not that long ago I was quite worried that Sony would either drop the camera market altogether or plainly concentrate on compact camera and mass market products. Now I am convinced that Sony really wants to take Canikon on for a fight in market shares, also in the upper market.
The A77 will be a very interesting product IMHO and it will show what translucent technology is capable of, and in this Sony is the real forerunner. I am not sure that I will run out and buy an A77 as ultimately I am interested in full frame cameras. For me the A900 was a real step up from the A700 in many sectors and I don't want to go back to smaller sensors, but then...that's me.
Anyhow, I hope you don't really want to jump ship in the hope that the grass is greener on the other side, as I believe that in this particular case it only
seems to be greener.
Stef.
