I received the camera today, and I ran every test I could think of and the ones you all mentioned. Camera works perfectly with both a DA 16-85mm and an old A 50mm f1.7. Wifi works (though I suspect the clunkiness of the app is not the camera's fault). Screen is in excellent condition.
Only 2990 shutter actuations. Pixel mapping fine. Sensor and mirror and viewfinder are clean. Pics come out great with proper metering. LiveView is good. Video fine. Flash works.
BUT...
It's apparent that the body fell in some dirt at some point. That need not be an issue for a WR body. The body is scuffed on the top and bottom. (As @fsge noted, the silver does scuff more easily) Nothing terrible though. The concern I have: You can see in the pic that there is a small crack in the housing around the screw just below the mode dial. It's not entirely cracked, and the piece is in no danger of falling off that I can tell.
Clearly not a good thing, and it was not mentioned in the ad. It was listed as 70-79% with "major cosmetic blemishes," but a crack seems like more than a blemish.
So, do I keep it?
- I purchased it from a reputable online dealer (not B&H or Adorama or KEH, but one you'd recognize)
- It comes with a 1-year warranty
- I paid $460 total for it. (Only came, as advertised, with body, body cap, a 3rd party battery, and the charger)
I've been watching used prices, and that price and the warranty is a really good deal.
What would you do? Thanks!
