I have gone as far as putting one of into my B&H Cart but just before clicking the buy button, the maddening questions came up again. 28-70/2.8: Not really a contender but one that is vaguely in the mix. It is just too big. 24-85/2.8-4: 72mm filter = -ve (I am partial to 62mm lenses as they tend to fit my size/weight criteria and can take my CPL and 6T - I managed to bag probably the last two at B&H). 35-70/2.8: 62mm filter = +ve for reasons stated above. Push/pull & rotating front = -ve although my 70-210 rotates as well and I live with that. Constant f2.8 = +ve. I went to look at pics on PBase for the two candidates and summary is.... Pics from 35-70 are generally of a higher standard. Not sure what that may mean apart from the fact that the shooters using it are more accomplished as I am sure they can produce similar work with the other as some shooters show. Although one might wonder why they have tended to select that lens for the range given the more limited cover. There are more wedding / pro type portraits with this lens. 24-85 seems more popular in the Far East or at least most of the shots appear to have been taken there. This might partially explain the pic quality thing. Not that Far Eastern photogs are bad but that many of the shots are probably by travellers packing this as a travel lens. Also shots are generally older. Obviously the lens is not as popular these days what with the Creeper and the like about. Is this down to quality or convenience? The 24-85 will mess up my "integrated filter policy" with no complementary 72mm lenses I can think of. I suppose it could be paired with the 180 and the wide end could be left to take care of itself. This will mean goodbye to the 6T, a replacement CPL, and the Fogcutter and 70-210 will be left in limbo. You guys in the States can afford to buy knowing you can easily sell off if not suitable but the secondhand market is basically non existent here and I'll have to wait for long spaced trips to the UK to dump any gear I don't want. Having said that, there is one due this summer. Any thoughts?
