- Sony hasn't shown the camera multi-generational commitment to photography that other companies have.
- Letting their α700, which was a capable camera, and their α850 and α900, which were excellent, be discontinued without any clear replacement at the time is worrisome. It feels like Olympus all over again, only more so.
- Sony has a lack of mid-range lenses. They have enough low-end zooms, and their "G" and Zeiss high-end lenses are as good or better than anything made by the other 1.5x and 1x camera companies. If Sony makes exactly the combination you want, buy it because it's great – and quite possibly the best available from anyone. But don't hope that Sony'll eventually make its current system into the "right" system someday.
I could further add that Sony has been developing the Sony Translucent Mirror Technology (SLT) for use in its DSLR camera line, but that brings up a final point in the anonymous email:
- I know a number of photographers who use Sony cameras, but they've never replaced their old Sony with a new Sony.
My take on EVFs is complicated. I much prefer the Olympus VF-2 over the 4:3rd camera series E-3x0/4x0/5x0/6x0 dark and narrow pentamirror those cameras used. However my E-1 and E-3 used bigger, brighter pentaprisms. And nothing quite matches the optical viewfinder on the OM-4 I have. That tends to lead me to prefer pentaprisms. This isn't the place to compare pros and cons of the OVF vs the EVF. It's a comment on the problems of acceptance certain key features of the Sony SLT cameras face, which will effect their overall success in the marketplace and longevity.
Going back to Sony's high end lenses, I've looked at both the 70-200mm f/2.8 and 70-400mm f/4-5.6 'G' lenses. Both price in at a cool $2,000/lens. Compare those prices to the 50-200mm f/2.8-3.5 Zuiko Digital high-grade lens which costs a more moderate $1,200. I can believe that the optical performance of the Sony lenses would exceed that of the Olympus lens, but the Olympus lens is environmentally sealed whereas the Sony's are not. Trying to find sealed versions of Sony lenses to match what Olympus has to offer in 4:3rds is nigh impossible. And spending that much money on a lens that requires a special baggy to keep out the water when it rains is a bit silly. And yes, here in Florida I have gotten caught out with my Olympus 4:3rds cameras in monsoon weather and not worried about the equipment.
Rumor has it that Sony will release a new 70-200mm f/2.8 lens at Photokina. I'm curious to see if it will be environmentally sealed.
