Interesting stat: I'm processing some photos right now (ones I took yesterday) and out of the first batch (500) I'm electing to publish 119.
All these photos were taken using manual focus lenses, so the reject rate is higher than normal (some days I elect to publish nearly everything I take) - I was specifically practising focusing my A135 at f2.8 for the first half and have a lot of discards as I was trying to focus on moving yachts whilst on a ferry. The latter half were taken on my A50 and have a higher publish rate.
1 out of 119 I'm not terribly happy with since it's slightly out of focus (looks okay at screen resolution, but blurry when pixel peeped) but I'm publishing it anyway since it's part of a series of portraits I'm doing and actually it's the best of the lot even though it's slightly OOF.
You can judge for yourself whether they are worth publishing or not - some of them I have posted in the lens thread (called "A135mm wide open - nice!").
Here's another one (the kayak is moving, I am on a moving ferry, it's a 135mm lens and I'm manually focusing at f3.5 - the DOF is only slightly wider than the kayak)
