Hi all, a lurking buddy here For about a year and a half i've been using my 40D now, after hitting the limitations on a couple of compacts/bridges. Since then i've been trying out different things with it, like shooting some wildlife/birds, architecture and landscapes, sports, people... the lot. For a while now, i've realised that i really like shooting landscapes. I'm not much of a sports person, nor a people person, and rarely shot them. Wildlife hasn't been much of a succes either, i'd need camp out for a while to catch the birds, and i can barely motivate myself to do that. It's now been a long time my tokina has been practically glued to the camera, i rarely take it off, and when i do, the 70-200 comes on. UWA has been treating me well, i love the wide view i can get with it. Last year when i was in San Francisco, those have been the only 2 lenses i used, and i think i got some good results with them. It was easy to take shots of the streets and views, and i liked it more and more ever since. With that in mind, i've been eyeing up the 5dII. It's not that i dislike the pictures i took with the 40d, but when it comes to landscapes, i've felt IQ could be better. When i take a look at the shots i took of SF, i think the sensor could really do with picking up more detail when using the UWA (better resolving, i think is the English term). The stitched landscape taken with the 70-200 pics of the same scape, are simply a lot more enjoyable than when i look at the UWA shots, but even then, it couldn't totally satisfy me. But it did work out better with a mountain panorama... But overall, i get good shots with the Tokina (1, 2). It's when a lot of detail comes into play that i find the gear falls short, like shooting the urban sprawl. Now, i don't think my solution would be to always take a series of pictures with the 70-200 and stitch, but a camera upgrade makes more sense to me. All that said and done, i would need a new lens to go with a FF camera. Since i like shooting UWA, and usually do this at 11mm on the 40d, i'd like a similar angle on FF. I'm considering the 16-35 II to be up to that. So, looking for some advice. Should i be considering upgrading the body/lens, do i myself need some upgrade , or am i imagining i could use an upgrade and just stick to my guns for now ?
