Was spricht gegen die Alpha700?
Laut dpreview ist der Autofokus sehr schnell und akkurat, nur das Rauschverhalten hinkt ein wenig hinter der Nikon D-300 und Eos40d hinterher - gegen diese und die Olympus E-3 wird sie dort relativ ausführlich getestet.
Schafft 26 RAWs mit 4,9 Bildern/Sekunde, JPEGS bis die Speicherkarte voll ist.
Das soll langsam sein?
Zum Sucher:
The A100 had a pretty bright viewfinder but the A700's is a big improvement, as it uses a solid glass prism (rather than a pentamirror). The view, for a cropped camera, is big, bright and very clear, and you don't need to touch the eyepiece with your eyeball to see the entire frame, which is nice. No surprise to see Minolta's eye-start sensor below the viewfinder.
Conclusion - Pros
* Good detail at lower sensitivities, very slightly more than ten megapixels but no massive gain
* Low noise at higher sensitivities although at the expense of detail (perhaps too much luminance NR)
* Excellent dynamic range at ISO 200 (more highlight range than we are used to seeing)
* Wide range of DRO options, manual settings deliver biggest difference
* Excellent long exposure capability, no noticeable hot pixels even at 30 seconds with NR off
* Good built-in flash, well metered, no color casts
* Full support for 'Sony Alpha' lens mount and all Minolta A-type lenses
* Good ergonomics, comfortable grip, great optional vertical grip (lots of controls)
* Dust reduction provided by anti-static coating and 'sensor shake' using stabilization system
* Environmental seals around controls (although not storage / battery doors)
* Built-in 'Super SteadyShot' sensor-shift image stabilization appears to work fairly well
* Good build quality, solid construction with no creaks or rattles
* Fast auto-focus, accurate and reliable
* Camera feels fast in use, responsive and no real usage delays
* Superb large, high resolution LCD (delivers full-color VGA; 640xRGB x 480)
* HDMI video output (up to 1080i)
* Five frames per second continuous, good buffering, superb write speed with SanDisk Extreme IV CF
* Clean, easy to follow menu system
* Quality glass pentaprism viewfinder (bright, large view)
* Customizable 'hard button' on camera rear ('C' button)
* Wide range of image parameter presets, addition of brightness custom adjustment
* Built-in AF assist lamp (with projected focusing pattern)
* Very fast USB 2.0 throughput (over 20 MB/sec)
* Easy to understand percentage (%) battery life display
* Supplied infrared remote control
* Value for money
Ich selbst würde die D300 bevorzugen, das liegt aber an den FBs bei Nikon. Ansonsten scheint die Alpha700 ein beachtliches Stück Technik zu sein, welche die von dir genannten Kritikpunkte eigentlich garnicht aufweist.
