First, congrats to the OP for scoring a deal. $1200 body and $300 lens + card for $1350 is a great deal.
BTW, for those quoting $1500USD for the body, you are apparently unaware of shopping comparison engines like Shopzilla or Google Shopping. It's a $1200 body at 42photo.com and Primotronix. At least the former has excellent rating on resellerratings.com.
I'm in a similar boat, only I don't have a backup SLR. I've been going over the facts and it looks like we're headed for a 7D price drop within a few months. I may not be a photography expert, but I am a retail/enterprise ecommerce consultant and use that experience to guide me.
The 7D is aging and even the T4i has advantages:
- smaller/lighter (nice for many)
- DIGIC 5 - better noise reduction, in camera HDR
- less shutter lag (according to B&H specs)
- better screen - higher res, touch screen, articulated
- EyeFi wireless
- $450 cheaper
I know, some of you do not consider all of those advantages, and I don't care to argue about it. My point is that it compresses the lineup, which certainly will give Canon execs pause when considering new additions. The 60D barely has room to fit. Common sense dictates that:
- if the 70D is released, 7D price will drop
- if the 7D MKII is released, 7D price will drop
- if the 6D is released, 7D price will drop
- on Black Friday, 7D price will drop
All 3 mythical cameras will have to tread on 7D territory in order to be a clear win over the T4i and 60D. Even if the first 3 don't happen as rumored at Photokina or the ceremonial Oct. Christmas toy announcements, you'll find some great deals on Black Friday. I assume BF happens wherever Christmas is commercialized.
Personally, the biggest advantage I can see in the 7D over T4i is the wireless flash control, because the new transmitter and flash you have to buy for the T4i to get the same functionality is almost $1K combined. That's not all, of course, but for my purposes (mostly indoor portrait/event photography), not a whole lot. It's also the main thing the 60D has over the T4i, as they cost the same now.
