Uh, you probably don't want an EVF for shooting sports. I wouldn't consider either of those. The refresh rate doesn't bode well for fast moving subjects.
If I were shopping in your position? I'd look at a 60D. You won't have to sell your current lens lineup either.
Posting in the Sony sub forum to tell people not to buy Sony cameras?
I pay very little attention to what forum the post is in when responding. I use the 'new posts' feature.
And yes, I will recommend against a SLT camera for shooting sports. Because it's not practical, or useful. The fact that it has 10FPS is not the "selling point" for sports.
From Wikipedia:
Advantages and Disadvantages vs DSLR
Advantages:
- Continuous phase-detection autofocus even during video, live view or continuous shooting mode
- Lack of camera shake due to mirror movement
- No viewfinder blackout while taking photograph
- Shorter shutter lag
- Exposure value, white balance and other settings can be easily and directly verified on the electronic viewfinder (and thus tweaked) before taking a picture.
Disadvantages:
- Less light reaching sensor, due to portion of the light being reflected to phase-detection autofocus array (approximately 1/3 EV or 21% in current designs).
- Refresh rate limited by the time it takes the sensor to form an image; in low light this causes severe stuttering of the viewfinder image when panning (e.g. if it takes 1/4 sec for the sensor to gather enough light to form an image then the EVF updates at 4FPS).
- No real-time viewfinder update at high shooting rates, the viewfinder shows the last picture taken instead of where the camera is actually pointed; mostly a concern with fast-moving subjects(Note: Some DSLR's do not update the image at all, as mirror is up when shooting. However, some will give you a gimps of what is being shot as the mirror and shutter reset for the next shot.).
- The EVF has far less dynamic range than the sensor, so the EVF does not properly show what will be captured.
- The bright light of the EVF in current implementations can cause eyestrain when used over long periods and can affect dark-adapted vision, causing temporary nyctalopia (Adaptation (eye)#Insufficiency).
- Over a period of time, the mirror surfaces can become soiled. As a result of this the mirror scatters the light rays and degrades the recorded image.
When shooting sports, the bolded areas are what I'd be concerned with.
