Ok, so I am not a new member here, I've been around for just over 2 years. You can tell that I am what would be referred to as a "lurker". I don't post very often, mainly because I don't feel that I have as much experience as many others here, but mostly, and I will be totally honest, because I don't want to make myself look like a fool. That being said, I know enough, from my "lurking", that many times the "which lens should I buy" type threads can aggravate some people because it really is such a personal decision. I know that the best way to make an informed choice is to become informed. That is why I am not asking you to make a decision for me, but rather, to provide me your opinion on the information I am going to give you to further inform myself so I can make the best informed decision. Mind you, my decision will not be made using just the information I gather here, but I respect the judgement of many people on these boards based on what I have read from them in the past. So let me get to my point. I am considering an upgrade, of either my body (I wish I could do that in real life, 'cause I need one!), or to keep the body I have and buy the best glass I can afford. The current gear I have is as follows: DSLR - Cannon EOS Rebel T1i (bought just before Xmas in 2010), with the Canon extra battery grip Lenses - Canon EF-S 18-55mm (kit lens) / Canon EF-S 55-250mm 1:4-5.6 IS (also came with the kit) / Tokina SD 11-16 f/2.8 (IF) DX / Canon EF 100-400mm 1:4.5-5.6 L IS / Canon 50mm f/1.4 USM The type of photography I am using this for is sporting events (my daughter is a swimmer), landscape, nature and wildlife, architecture, and macro (I know I don't have a true macro lens yet, but I intend to get one). I am not really into portraits, but many times am asked to take "family photos" whenever there is a gathering. As I said above, I am looking to upgrade the body and keep the lenses I have, or to keep the body I have and upgrade the lenses. Of the research I have done on bodies, I would be leaning towards the 7D. I have read and seen reviews where it was comparable to, if not better performing than the 5D Mark II. If I were to keep my T1i, I would definitely be getting the 70-200mm f/2.8 IS, as well as a quality macro lens. In your opinions, what would be the advantages and disadvantages of these two scenarios. OR, is there one I have not considered, that I should? I would love to say that money is no object (wouldn't we all!), but I am mostly interested in your opinions from a performance aspect. I look forward to your responses.
