Wow, so many replies so fast, thanks a lot for taking the time (even reading the redigiously long post...)
I think I got two very good points here. Firstly ScottM´s point about going to FF and maybe not liking 17-40 anyway, if 10-22 is wide for me on crop 17-40 would be as well on FF. I mean I like the WA too, but would really need it so rarely that now I wouldnt spend my limited budget to 10-22, and if going to FF one day there will be second hand 17-40´s available anyway. Thanks Scott, this is obvious point but I really didn´t think it through properly for some reason!
Another, even more relevant and interesting view came from Wim. Meaning why go to crop if it seems so difficult to find the right glass for me what ever the reasons. I thought this over the night and more I think it more I agree. I just started planning this whole thing based on new gear, but it is absolutely true that second hand 5D´s are decently priced. And then I´d go right a way to 24-105 wich would be the all-arounder I think I would find useful for my needs, and is actually in nice sale at the moment in the local shop I´ve found reliable and good. The same dealer has several second hand 5D´s with price 850-950 eur (40D here 699 eur as new).
I know this start´s to be pretty off-topic, but shortly, could someone advise a bit what to look for in second hand body especially? What is the amount of pics taken you would concider too much? I think I´d take some 5 000-10 000 shots / year maybe, difficult to say as haven´t had my own dslr before and who knows how excited I get shooting anythign that moves .
Also if someone could have quick pro´s and con´s on 40D vs first gen 5D, would I really miss anything than some lenght on lenses and speed on continuous shooting for sports? And yes the UI and maybe LCD overall, but everything else just pro´s? Would love the weather protection, more I think it now. Must admit I´m bit rough with the gear often and can easily forget it where ever once and a while..
And what comes to the 17-55 / 17-40, that´s clear now, if it´s crop body I´ll go for 17-55 and that´s it..
Sorry for such a long monolog again.. It´s just so much to ask and such a big thing for me getting the dslr after planning for it for about 5 years, wan´t to make the right decission.
Out for now, thanks again!
