EOS Bodies / Re: Canon EOS Rebel T4i/650D Specs [CR2.5]
« on: May 18, 2012, 06:43:34 PM »
Well, part of it is that they are different technologies. The way a Canon camera autofocuses for pictures is different than how it does in Live View, and video uses the Live View technology. Canon would have to adapt the SLT technology with a translucent mirror to auto-focus in the exact same way a Sony does. In doing so, they'd give up all the photographic advantages of the mirror, which isn't worth it. Basically, the Nikon autofocus sucks because it doesn't use the focus sensor (due to the mirror being up). I doubt Canon will have solved this in a way that makes it comparable with what sony has in their SLT's, let alone what the FS-700 has.

Sorry to tell you, but the NEX 5n does NOT use SLT technology. NO SLT, NO phase detect sensors being built into the imaging sensor like a Nikon J1/V1. The Sony NEX 5n doesn't use any form of phase detect for focusing, none, zip nada.

The NEX 5n uses contrast detect auto-focus, just like the quick focusing Olympus cameras. If Sony, Olympus and Panasonic can build good contrast detect auto-focus, why do you feel that Canon is so incompetent that they couldn't ???

If Canon had solved those issues in some brilliant or ingenious way, they'd have put it in the 5dIII. That they are just leaving it to the T4i tells me all I need to know....it would have made pros angry since its not very good.

Check-out the video test of a Sony FS 700  https://vimeo.com/40369782  the follow focus works very well. The test was done by Andrew Young, his work has received an Academy Award nomination, multiple Emmy Awards and the Grand Jury Prize at the Sundance Film Festival.

Don't confuse the Nikon D5100 auto-focus, with a Sony auto-focus. My NEX 5n, using face detection, does a good job of keeping a person in focus as they walk around a room, even at f/2.8. If Sony can do this, why not Canon ???

Sony is keeping a 16 mp sensor in their new Nex-F3 and A37. Perhaps both have determined that the marketing benefit of ever-higher megapixels has reached the point of diminishing returns.

Both are bottom of the line cameras. So I wouldn't read too much into it. We'll have to wait to see what happens with the 24Mp NEX 7 and a77. Sony isn't Canikon, they seem to march to the beat of a different drum.

So who has worked in the field with a mirrorless body.  Try doing very early morning and very late afternoon landscape work and see how pleased you'll be. The optical viewfinder lcd is the weak link here. Great idea but at the moment a "nitch" market at best.

I've used the Sony NEX 5n.

It has a 1/4 20 thread in the bottom, just like a DSLR, so that you can use a tripod. The screen brightness can be cranked-up for use at the beach. It has an APS-C (1.5x) of equal to or better than Canon quality. Why do you think that this Sony or a Canon Mirrorless wouldn't work for landscapes ???  ???

Assuming you've already got a bagful of Canon L glass, what alternatives are you suggesting? If the spec list is as detailed, and the build quality is on a par with 5D3, I'd pay over $2k for it in a heartbeat.

Paul Wright

Why do you have a bag full of L glass ??? Why would anyone have a bag full of any kind of glass ??? If you don't use a lens (or anything else) at least once a week, you are better off renting it as needed.

If a lens doesn't regularly make me money, I see no need to own it. YMMV

After using 5D III, I properly will not go back to crop sensor anytime soon. ;)

I've used a 5D3, but would rather have an APS-C camera. Different strokes for different folks.

This same thread over on EOSHD somehow turned into a S___-talking match between the blog owner and Phil Bloom.  It's worth the price of admission.

Thanks for posting :) Good read :) :)

I'd like to see someone make a B&W DSLR, but Canon wouldn't do it 'cause they would be afraid that it would cannibalize their color DSLR market ;)

When and if, Leica builds a R10Digital maybe they will include a B&W model.

My guess is that Canon is lining up another oddity to not cannibalize their DSLR market...


One of Steve Jobs's business rules was to never be afraid of cannibalizing yourself. "If you don't cannibalize yourself, someone else will,"   http://yastrow.com/nlarchive/2011/cannibalize-yourself-12-20-11.html

The DSLR market is flat, but growth is occurring in the in the mirrorless market -- so canon needs to go there. But not with their typical "no-cannibalizing-allowed" attitude. Lets hope they get it right, 'cause if they don't someone will eat their lunch.

If the size and style of your camera system is more important than the actual images it produces (or it's just good enough), then there is nothing wrong with choosing m/43 or NEX. It may be the right choice if you don't care about the involved compromises. Looking at the m4/3 results I'm not convinced that it is much better than a premium P&S (like G1 X), while NEX APS-C sensor being more attractive which still cannot compete with Full Frame beauty.

It all depends on what you are doing. I shoot advertising with a Canon APS-C. I know of some ads that were shot with M4/3 and even one cover shot with M4/3.

Always use the right tool for the job. And sometimes M4/3 is the right tool.

When the Canon mirrorless and it's lenses arrive, I'll take a look. If they are the right tools I'll buy into the system. If not I'll look elsewhere.

Canon's 3 to 5 lenses will include 18-55mm, 18-85mm, 18-200mm, 18-400mm and 18-600mm variable aperture zoomz  ;)  ;)  ;) And No Primes Ever  :(  :(  :(

BTW this is SARCASM. But I fear it is close to the truth when it come to primes.

For existing mirrorless, Sony mirrorless (E-mount) cameras can AF with Sony DSLR (A-mount) lenses ...

Sony makes two adapters. One is just a mechanical adapter and uses the camera's autofocus. The second one has a built-in SLT autofocus system and the focus is as fast as their DSLR.

Nikon has the phase detect sensors built into the chip, so it can focus as fast as a DSLR.

Hopefully Canon can do something like the Nikon solution, for fast auto focus with either EF or the native mirrorless lenses.

Statistically yes, real life no

How's that ??? An 85mm on an APS-C camera has approx the same field of view as a 135mm lens on FF.

An EF 85mm f/1.8 is 3.0" x 2.8", 15.0 oz. and an EF 135mm f/2,0L is 3.2" x 4.4", 1.7 lbs. More than a .7 lbs difference seems real life enough for me. YMMV

Have a nice day :)

I'd guess the limates of optical technology will prevent things going too far in this direction,


There are some M4/3 lenses that have good IQ. Leica's DG SUMMILUX 25mm F1.4 ASPH is one of them. And Canon has built high quality lenses, for 2/3" Broadcast Video cameras, for a long time.

the NEX maybe small but its still ulimately using the same sized sensor as crop DSLRs.


That's the point. A NEX 7 (1.5 crop) is much smaller and lighter than a Canon 60D. And the Sony sensor is 24 Mp, not 18 Mp like the Canon.

But time marches on, and I'm sure that the next generation of Canon APS-C sensors will have more IQ than the present Sony sensors. Manufacturers leap-frogging one another is how high tech works -- everyone gets to be the leader for a few weeks.

A high MP FF camera does seem like a good opportunity to take the mirrorless route to me though.


The problem with FF cameras is that they require large/heavy FF lenses :( A Leica 25mm f/1.4 M4/3 (2X crop) lens weighs 200 grams and the Canon 50mm f/1.4 weighs 290 grams. Percentage wise the difference between 200 and 290 is very large.

This is also a problem for Canon APS-C cameras because they use FF lenses, except for the EF-S zooms. Even though I'm an APS-C Fanbo, I can see a future need for M4/3 cameras, if you really want to decrease size and weight even more. Me, I'd be happy with a NEX 7 sized CANON CAMERA with 14mm f/1.8, 24mm f/1.8 and 85mm f/1.8 primes.

FF DSLR's seem well suited to the jurno/sports/wildlife users given the advanatge in AF performance ...


The Nikon 2.7x crop mirrorless cameras (J1 & V1) have the Phase Detect Auto Focus sensors built into the chip and are said to focus as fast as Nikon's DSLRs :) 

" ...Very DSLR-like in most aspects, including speed and tracking ability ..." & " ...This is the result of phase detect sensors being built into the imaging sensor, coupled with the high frame rate of the sensor ..."  http://www.sansmirror.com/cameras/nikon-v1-review.html

Like it or not, "time marches on" into the high-tech future. :)  :)  :)

255

Agreed - we will be using MF with 200mps

My guess is 80 Mp Smart Phones. That also shoot 4K Digital Video. ;)

If Moore's Law continues to function, we'll have MFD IQ in a very small camera very soon. Bet on it!
