Can anyone describe the T5i time-lapse video capability? I understand (and I may be wrong) the T4i cannot and its rival the Nikon D5200 can, but I read somewhere that the T5i can with a USB cable and PC. Can someone shed light on this rumor, please?

paladolphin, how will the USM focusing of the efs 15-85mm work with the t4i/t5i?

Presumably in the almost same way it works with the predecessors of the T4i/T5i. As the EF-S 15-85mm doesn't use the STM system, you won't get the smooth focus or benefit fully from the hybrid AF in Live View.

USM vs STM: That's a very good question. But first, let me clear up any incompatibility issues: USM lenses will work on future cameras and STM lenses will work with older cameras.

First, one of the main objectives of the STM lens design is to be silent enough for the built-in microphones to not pickup on noise caused by focusing while shooting video. The motor's design is borrowed from dedicated video cameras. Although an USM lens is quiet, it's not enough to avoid being completely picked up by built-in microphones; You've got to attach an external microphone, not a consumer-friendly issue. Pre-T4i DSLRs with video capability will benefit from STM lenses in the sound department.

Second, Canon must have not found the USM design (first introduced in 1987) beneficial for video. For still subjects, USM can one-shot focus slightly faster than STM. But, USM does this by starting close and focusing far; If it misses focus, it starts over. This causes searching, which then takes longer. When tracking a moving subject using a servo mode, as in video or Live View, USM doesn't appear pleasing. It wasn't designed for video.

STM was designed for smooth video focus; It's a slightly slower, but more pleasing. It's also designed to track focus on moving subjects. And its motor doesn't have a problem going backwards; which means if the subject is coming closer, it doesn't have an issue; it just tracks it smoothly. The STM lens needs information from the "Hybrid CMOS" sensor in the T4i/T5i to focus fast; which means pre-T4i model cameras will focus poorly in video and Live View modes.

If you use the T4i/T5i with older USM lenses, now they will focus rather quickly in video and Live View (how quick is for future tests, but for sure, it's not a 1-2 second wait anymore). But then again, you will likely get a jarring snap focus or have that hunting in your footage as the USM motors are not optimize for video shooting. The T4i's "Hybrid CMOS" sensor will have no beneficial effect with USM lenses. Silent as USM are, they may still have sound that can be picked up by the camera mic. The IS might also be nosier in the older non-STM lenses; a source of irritation for those who do video.

So, if you've got existing L-series USM lenses you want to use on a T4i, then you've got a dilemma. Will Canon ever make an L-series STM lens? Not if they're only targeting STM to consumers.

I talked to my Canon expert at National Camera Exchange (http://natcam.com) and verified what I just described about how a USM lens will work with the T4i/T5i (see above).

So then, I wanted to confirm another rumor I'd heard that the EF 40mm f2.8 pancake STM lens produces noticeable noise on the T4i built-in microphones shooting video while focus changes. He confirmed that it has been a regular complaint with customers with this particular lens. :cry: Personally, I'm still interested in the lens, but for still photography. I'm going to go down to my camera store and play with it; I'll let you know how that goes.

My guy explained that eliminating focusing noise was not as high a priority for Canon than I had thought; So, I just wanted to correct what I previously said. He said that if you're serious about video, you buy an external microphone, bottom line. Just like professional DSLR cameras do not come with a lens nor built-in flash, professional video cameras don't come with a microphone.

The next bomb he dropped on me is that Canon has pulled the T4i line in anticipation of the T5i; He was audibly upset about this. He didn't even have a T4i to diagnose a problem I was having with mine; He had to use a T3i. So, if you can get your hands on a T4i at a decent price, you will want to take that into your decision when choosing between the T3i/T4i/T5i.

I've heard another feature new to the T5i: digital zoom. Rumor has it that the T5i adds digital zoom 3x to 10x; a feature that used to be on much older models. Although not so useful for still photos (better to zoom in post-processing on a PC), I can see it being very useful for video. Digital video zoom saves memory card space and is difficult to achieve post-process. Saving space while recording means longer recording time.

It makes me wonder how it is implemented? Probably using the front dial to control digital zoom and the lens ring to control optical zoom.

Does anyone know which previous DSLR camera model had digital zoom?

Sounds a bit confusing. The 600D had the optional 3-10x digital zoom in video mode which it did by effectively cropping. For video that is no problem since the sensor resolution is far higher than the video anyway, but it doesn't save any storage space since the output resolution is the same. Zoom in and out using the same buttons as you would when reviewing a still shot.

My bad. I was applying still photo post-processing (pp) to video pp.

Oh, that's how they implement it. It makes sense since the labels are there. Since I'm coming from a G12, I think of sliding my right index finger left/right for zoom; feels more natural.

Seeing that my T4i is missing digital zoom, I'm envious after watching the Rebel T3i sample video 7: Moon with 70-300mm at 300mm and 10x digital zoom (4800mm equiv):
http://www.cameralabs.com/reviews/Canon_EOS_600D_Rebel_T3i/video_review.shtml
At 4800mm, only half the moon fits in the frame! Awesome! The reviewer says that at 10x digital zoom that there is loss of quality and resolution. If I understand this correctly, at 3x (or 2.5x) digital zoom there is no loss; it's only higher than 3x that you start to loose quality and resolution.

I'm a little surprised they took it out of newer models... I wonder why they did that. Still, I don't do much video so it wouldn't be a loss to me.

Sometimes you have to ask: Canon, what were you thinking?

I haven't done professional video since 8mm Video8 http://en.wikipedia.org/wiki/8_mm_video_format. I did consider video when purchasing the T4i w/STM lens. I was seriously considering saving money and buying the T3i, but wasn't aware of this digital video zoom feature in the T3i and missing from T4i at that time. Canon's $250 instant rebate clinched the decision for me. I have no buyer's remorse: The feature set difference between the T3i and T4i is significant; between the T4i and T5i, not so much so. I guess that's why Canon discontinued the T4i; It's decisions like this that upset loyal Canon customers.

Just received an e-mail from Amazon regarding the T3i/T4i/T5i. The e-mail gave different (higher retail body-only) prices than what showed up after visiting their Website. Note what looks like a price difference mistake where the T4i with 18-55mm EF-S II NON-STM lens is $0.99 more.

$578.99 Canon EOS Rebel T3i 18 MP CMOS Digital SLR Camera and DIGIC 4 Imaging with EF-S 18-55mm f/3.5-5.6 IS Lens

$648.99 Canon EOS Rebel T4i 18.0 MP CMOS Digital SLR with 18-55mm EF-S IS II Lens, $648.00 w/o lens ($0.99 difference)?

$899.00 Canon EOS Rebel T5i 18.0 MP CMOS Digital SLR with 18-55mm EF-S IS STM Lens (avail. 4/19/2013)

This is not news to me as I have been following this on amazon since i decided I wanted the 650d, 700d or the 70d (please look in the 70d thread I made an important update).

by the time I save minimum money to buy what I want, the 700d with the 18-55mm IS STM may cost about $750USD (I HOPE)!

In the mean time I am now patient with the with what ever canon has in store for us by the time I save for the camera I want.
