This could actually end up being pretty cool...hadn't thought of it being an easier way to set AF points.

UPD: Yeah, according to now-increased auto ISO (12800), it's new. Stereo mic is the nice addition as well.That might be the effect of Digic V on the current sensor, or the result of a few tweaks. Until they say its a new sensor, I'd assume its the old one.
So does this autofocus in live view? I saw tracking in the live view focus modes...That's the theory, that it can AF in video mode
As far as this lens goes, it is a very smart move by Canon in that it allows DSLR owners to carry a much more compact kit on their walking about forays, it affords newbies low cost entree into the land of the oft vaunted prime lens, and gives Canon breathing room while they finish up their mirrorless offering.Comparing this, with theoretical dimensions, to the 35mm f/2, at most it will save a few oz's and about a 3/4" in lens length. The 35 f/2 is 1.7" long and weighs 7oz, the 50 f/1.8 is 1.5" long and weights 4.5oz, and the 28mm f/2,8 is in between those at 1.6" and 6oz. So Canon already has 3 lenses around that focal length that are light and small. And one that gathers an extra stop of light at a cheaper price.
STM vs USM? What's the technical difference? Other than that STM is, I assume, worse somehow.
STM is a stepping AF motor. If you want to see how it works, its already used on the Nikon 1And if we're going by previous rumors, the point of STM is that its silent (I'd assumed "S" in it). So, it may or may not be better than USM in terms of actual focus, but for video purposes, they key is that it won't make noise. That's in theory, of course
3. Function dial has a different texture--no lock, great!Wouldn't be so sure about that...it just might be more recessed than the previous locks, and thus harder to see. Seeing as they've included the lock in everything lately, I'd imagine it will still be there.
Yep I'm inclined to agree on the 30mm argument, but not EF-S. Could be the 40mm is the first of a small pancake parlour of Canon glass.Well EF-S would be the only way a 30mm f/2.8 gets released. Seeing as it would be crazy for Canon to release an EF 30mm f/2.8 non-IS lens for <$200 just weeks after releasing an EF 28mm f/2.8 IS for like $7-800. Nobody would buy the IS version.
hopefuly a mirrorless FF which accepts EF-S lenses.You do realize that's basically impossible. EF-S has an image circle that fits a crop sensor, on a full-frame sensor, you'd end up with a vignette covering the difference between a crop and full-frame sensor.
Starting to look like f2.8 is going to be the standard minimum for non L primes....Based on the 24mm and 28mm, I'd go ahead and say the former...neither are "cheap" primes or anywhere close to it. That said, if f/2.8 is the standard for their primes, they'll stop selling primes. If the 17-55 does f/2.8 and IS, there are limited reasons to get the 24mm adn 28mm primes. And if you need low-light for cheap, you'd get the 50mm f/1.8 over the 40mm f/2.8.
This could mean two things, Canon pushing people into buying top end primes for anything less, or alternatively realignment of the ranges to have f2.8 "cheap" primes, entry level L primes and moving the current top range primes up the price list.
Tamron 70-300 VCI think you'd be really disappointed with this lens on full-frame, especially one that has an awesome AF system. Its slow to focus and while the IQ is nice for crop (especially at its price), I don't think it'll hold up to full-frame. If you do go Set #1, I'd either trade the 70-300VC for the 70-200 F/4, and you can decide whether your macro lens or 70-200 lens needs IS more.
My other lenses don't have a problem though.Send it back. You paid a lot for a new lens for it to work...it should work. Since you've ruled out most of the possibilities, its probably defective. I wouldn't risk screwing up your return by using the eraser method, etc on brand new contacts.
Yet, I think there's little doubt there is significantly more demand for the D800 models versus the 5d3.I see this posted a lot, and yet I've never seen anything confirming it. I've seen posts that retailers are saying they are selling 10:1 on the 5dIII v D800, and vice versa. I think both nailed their target audiences well, its just a matter of which audience is bigger (studio/landscape v wedding/street/event)
If there's an AF/MF switch, I assume there's a motorYep, that's what I was thinking.
+1 FredMiranda.comYep. Costs you $10 to be able to do it, but with all the gear you want to move that's nothing. Its basically Ebays listing fees. You might sell them higher on Ebay, but by the time the fees come out, I doubt you get more.
Unfortunately that's too expensive for most of us ! that's why a new version of the 100-400 L IS is absolutely neededYeah, although that too will probably be $2000-2500 if the price increases are consistent.
