*istDS2 sounds like nothing but a minor upgrade, if that. It might even be a downgrade based on the price. Is there anything new about it other than the filters?
Not a lot new really. Which makes this the fourth in a series of confusingly similar DSLRs. Well done, Pentax :(
Of course the 12-24 is old news. The only real news here is the 540 flash. Is that guide number better than the Sigma Super?
The sigma is GN 50m @ 100ASA, 105mm zoom reflector setting. The Pentax one is GN 54m @ 100ASA, doesn't say what zoom thats at.
So yep, its a bit better. Probably cost a bit more too. Love, Light and Peace, - Peter Loveday
