Big surprise: Canon T4i

Canon still advertises this one as an entry level camera. I'm sure the menu is still messed up and more difficult to navigate. Seems that is one thing Canon does to downgrade the plastic cameras for the pro level.

Is that your humble opinion or just an assumption?

From Canon press release. Yes Jason it's still plastic. Not sealed against dust or moisture. It is smaller and not as easy for a big hand to grip. Canon says it's the most "consumer-friendly" dslr to date.
Canon states: "Our Rebel line of cameras bridges the gap between the casual photographer and someone looking to advance their photography ..."

Canon says "The EOS Rebel T4i helps novice photographers capture great images and video."

The Canon reps at NAB stated that one thing Canon does is make the menu a little more difficult or taking more steps on the consumer cameras than the Pro grade.

No Jason it's not my humble opinion or an assumption ... it's Canon and their international sales program. There still is a difference and a big one between the Rebel plastic cameras and the more Pro grade. A little reading up before questioning will help keep things peaceful here on the forum ;)

So would I buy one. Yes if I was using the Rebel line of cameras I would definitely upgrade. I also would definitely not sell a 5D MKII, 5D MKIII or a 7D to buy and use the Rebel grade camera. Even though the electronics are similar or even as good; the basic menu system and construction is not what I personally use. This part is MHO.

Making the T4i as well as prior models dust proof and even moisture proof is not difficult. Delkin makes some nice silicone based slip on (tight) rubbery covers. I have yet to have any issues with dust, even prior to having installed the covers. Considering I live in the desert and we have had several haboobs (dust storms - but I like the term haboob because it sounds naughty), I have still not encountered any issues whatsoever. I for one prefer to spend money on glass as opposed to bodies. I have tried now 4 several years to justify getting higher end bodies and have yet to do so. It is just not necessary. I sell high end fine-art photos from these cameras all day long - so the sensor as far as the eye can tell is just dandy on the "consumer" or "pro-sumer" class cameras. It's not the camera that makes a difference, but rather the person behind it. IMHO

So, what is a good all around glass for a T2i?

70-200 f/2.8 IS L. This is my favorite for the 5D II/III and 7D.

I have a question: What happens if I take a lens for T4i and use it on 5D 2?

My favorites are 50mm 1.4 prime (original canon - first version all metal body), 10-20mm ultra wide (sigma), and a 70-200mm L series zoom with 2x conversion and a 300mm IS (canon) - I also once in a while do experiments with alternate glass from the old days as well as some of the fun stuff available today. Was considering Lens Baby but I can do all of those things in post with software I have.

@vader... +1 on the "OG Canon" 50mm, and Sigma 10-20 :) - just picked up the 50.

Today I will start playing around with a T2i for a few weeks. Then I'll decide if I go for the T4i.
