EOS Bodies / Re: T3 Sensor - question...
« on: February 13, 2011, 03:28:18 PM »
That said, the reason I've held off on buying a secondary body is because I haven't been impressed with Canon's APS-C sensors.  This new sensor in the T3/600D has a lot of potential because its photosites will be bigger, and it'll have the much more modern processing engine.  Somehow I doubt Canon would allow the cheaper camera body to outperform the more expensive ones though, so I'm not getting my hopes up. ::)
I am totally agree with you and the rest of the discussion on your post. Just hope Canon is smart enough to turn the T3 into  a High ISO performer and let the people that want 18MP to have the 7D, 60D or the T3i. I am going to throw another coal into the fire. Last night I was looking at the noise performance (only) of 40D, 7D and 60D with DXOmark. At ISO1600 and 3200, 40D is the best performer by  a slight margin. This says a lot about the noise and pixel size.

EOS Bodies / Re: Canon 40D Shutter button **FAILURE**
« on: February 12, 2011, 09:10:55 PM »
Hi CR,



The diagnosis is confirmed by the button pressing half way to focus, focusing successfully and when the button is completely depressed the shutter does not go off.

heh, I did not know this was a common issue. I have a 40d and this issue occurred with me when I was at angkor in cambodia. I t hought it was actually exposure related because I didnt have any issues taking photos of bright scenes, it was in dark scenes that the trigger would not fire.

That said,  I havent had the issue since (or maybe so intermittently that i dont even recall it happening) and I didnt do anything to 'resolve' it.
I have the same problem with my 20D after 40K activation. Now it is sitting at the bottom of my " junk pile".

EOS Bodies / Re: 60D vs 7D with FF in the near future:
« on: February 12, 2011, 09:07:55 PM »
Ok so now I got the lenses down, only now to decided on the body. I like them both, I prefer the 7D a little more, probably the one I am going to get after the rebates roll in. I heard great things about it's AF, especially in low light. Maybe I should download the manual and get a head start, so when it comes I know what to do. Just a question, I never tried this with my A700 (12mp, I could lower it but no point at 6mp), but if I was to lower the MP's (if possible on the 7D, in the menu), to lets say 12mp from 18mp, I should get better hi ISO performance correct?
I got a feeling that you are looking for a "Transitional camera" that you will be moving into FF in December. I have a suggestion that is a little bit crazy and It may work for you. Spend $450 for a used 40D and $700 for a 17-40mm F4 L lens.  This is an excellent lens for APS-C sensor (I am speaking from my own experience). It should take care of most of you need (27mm to 66mm equilvalent)except when you need the telephoto usage. The lens is a true FFlens. So you will have an utawide to normal zoom lens for your FF. As for the 40D, at ISO 1600 its noise level is more that acceptable. At ISO 3200,  you will see some noise.You can sell your 40D later and get most of your money back.
Do not let the metal body to be your determioning factor of choosing between 7D and 60D. The shutter release switch may fail before the rest of the camera body. Please see other posts in this forum.

that's basically the way firmware works already.  minor updates are released via firmware patches to your existing cameras.  you are expected to pay for major revisions (aka purchasing a new camera).

Canon should sell the "major firmware upgrade" and let you keep the camera. Just like a lot of people upgrade their PC operating system from "Vista" to "Widows 7" without buying  a new computer.

I agree with Osiris 30 that we should not expect the noise will be substantially better just by switching to  a newer processor. I have both the 20D and the 40D. The High ISO  (1600) Noise on 40D is worst than the 20D by a very very  slight amount even the 40D have a newer  processor. In the semiconductor business, sometimes a newer product may be just  a cost cutting ( by going to smaller geometry and hence ends up with a smaller chip) move rather than a performance improvement. To be fair, by going to smaller  geometry, there may be a gain in  the processing  speed of the processor.
Therefore, the real improvemnet in noise is by improve the sensor of the XSi ( Gapless microlens, shorten the metal connection, amplifier built into each pixel etc. which is already done on the 7D sensor) and use it on the T3.  Canon may end up doing that in order to out perform the Nikon with the same pixel count sensor. That is my wishful thinking.

I just think that Canon and the rest should follow a computer software sort of model - where minor revisions, even the addition of some features are considered minor, are free while you are expected to pay for major revisions.


There can be a middle ground,  if Cannon can follow the software company's business model. Minor up grade of firmware is free (canon has been doing it for along time). Major firmware upgrade ( e.g. addition of functionality)will be sold to customer.  Just like the Phtoshop, If you have CS2 and want CS3..You need to pay for it.  That will save the consumer a lot of money.

So the T3 (Canon's lowest end DSLR) gets a brand new sensor (the MP count is different than the 450D as is the ISO performance), so I started doing some math..

Long story and boring math aside, I'm left with the distinct impression this is a cut down 5D-Mk III sensor.  I'm curious to see if anyone else has given this any thought.  I just don't see *any* reason for Canon to build a new APS-C sensel w/ gapless microlenses for just one camera (and their cheapest at that).

Anyone?

It may be from the Rebel XSi. It is impossible to "cut" a FF sensor to fit an APS_C camera without ALL new tooling (All new Wafer fab process mask set). Then it becomes a new sensor by default.

It will be nice for Canon to throw in the Gapless micro lens to replace the gapped micro lens on XSi.  This will make the 600D to be the best Hiogh ISO Low noise DSLR for the Canon line up, assuming everything else are equal.

...everyone except Leica seems to be pointing their brands at the casual user.

and also Fujifilm.

Fuji X-100 is not in the same league as Leica M9. X-100 is with a fixed lens and APS-H snsor. M9 is FF with interchangeable lens.

Yeah, I agree, but the weird part is the 600D is suppose to be under 60D or 7D, so making it better than those is weird without upping the other's as well..
The 600D may have a very slight edge on image quality (???) However, 7D has most of the feature and a metal body (for better or  worst is a personal choice), 60D lack a few features from 7D and with plastic body. 600D is plastic body and with a lot convienence and feature missing from 60D. picture quality is not the only thing that determines which is a better camera.

Based on the ISO range supported this sounds like a new sensor, with gapless ML, etc.  In short, this camera may deliver stunning IQ.. ironic that I might want to buy the cheapest SLR Canon makes, after years of steadily moving up the chain.

If it can have a precision focus screen added to it, I may have no choice.. certain things just don't need a million FPS.  It would be great to have a tiny, high DR monster street cam.
I agree with you. However, even with precision focusing screen, your focusing accuracy is hampered by the EF or EF-S lenses built-in coarse manul adjustment. They have less than 1/3 turn for the whole focusing range. If you look at the old manual focusing lenses. most of them have about 3/4 turn for the focusing range. That is a factor of 3 for the accuracy difference.

Either the T3i or the T3 press release make any claim on the gapless micro lens on the CMOS sensor. That is interesting. Because we all known that all 18Mp sensor from Canon are gapless. Is Canon avoiding the subject in order not to make the 60D or 7D looks not worth the money???

Those knowledgeable photographers who post here are not typical buyers of the Digital Rebel.  This camera is aimed at users who do not know or care about the technical internal construction.  Most buyers would not have a clue if they listed it.  It has become a standard Canon design feature.

Here is what they do say.

"This first-class sensor features many of the same new technologies as used by professional Canon cameras to maximize each pixel's light-gathering efficiency"
If the T3 sensor is really "gapless" It may be the best camera from Canon for High ISO with Low noise, better than the 60D.

EOS Bodies / Re: 60D & 7D Rebates coming February 20
« on: February 08, 2011, 03:11:14 PM »
Digitalrev is based out of Hong Kong, there's a good chance you'll have to pay customs taxes when it gets delivered. Also rebates are usually only through authorized US retailers.

You will also end up with a "International warranty" (U.S. excluded). Anything goes wrong within the warranty,  Canon U.S.A. will not touch it.

That's why I said I believe the most one should edit is CameraRAW. No editing is impossible - but all that Photoshop "stuff". -> if I want a fake image I'll ask for a computer simulation.

And Photoshop - I don't have the patience to spend ages on an image - in CameraRAW I'm normally done with it in less than 1 minute. Yes, I do end up shooting the odd HDR - and that's a deviation from my "normal course" but not that many, and then I try to make them look as normal as possible.
Oh, and I don't have the time to spend on figuring out all the depths of Photoshop.

I still call an image that has taken a lot of editing, especially in Photoshop a fake image.

So by your standards, the fact that I shoot film makes me a better artist/photographer than you?  Do you even realize that how you are defining art, you are essentially contradicting yourself?  Arguing whose art form is more "real" in a digital vs digital discussion, lol.

It's pretty ignorant to see any form of art better or worse than the next form.  Painting, drawing, sculpting, photography are all just different forms of art with different ways of expressing ourselves.  Some might be more difficult, some might need more patience, and a different mind-set, but none of that makes one really better than the other.  That all just depends on if the artist has a true vision of what he is after

Digital vs film is like comparing painting vs watercoloring.  They both require different techniques to get to the same result: YOUR VISION.  Personally, I do not enjoy overly digitally enhance shots and half the time I think the work looks mediocre at best (crappy art), but it is still art! 

Someday, you will figure this out and appreciate art as a whole

You do have a point - however, in photography the art should be in the action of taking an image.
-> Right now you can take a rubbish image, if you post process it enough it'll look like "something" - but it's no longer photography.
Film had a natural limit to what most people could do. Yes, people have been removed from images (Soviet times) but normally it wouldn't be done.
Now you shoot a rubbish picture, edit a lot in Photoshop and voila, you have a result.

It is no longer the quality of your photography work that counts, it's the quality of your photoshop work.

If you want to show of your photoshop work, then do it separately and don't claim it's photography.
With respect to film - the issue I'd have with film is cost - but overall I'd say that provided film is able to capture a scene (I don't think you can get usable ISO 6400 film) then that's real photography.
And obviously, not everybody can afford the cost of developing a lot of film - so CameraRAW in a way replaces it, additionally, it does give you some control, but does not allow you to modify an image so that it is no longer photography. In CameraRAW you can only do "so much" - the same is true for film.
With Photoshop you can do anything - and then it's no longer photography.
Photoshop is just another tool . If Ansel Adams can spend hours or  days to "create" a picture that he likes and become a great art piece, why people cannot do the same thing  with the photoshop? Whether it is an art or not, it is in the hand of the user, not the tool.  Same situation as the example about the same song sung by different singers. It is the singer, not the song.  Tools changes with time and we need to adopt the situation.  When is the last time that you use ALL hand tools on a wood project ? Using power tool does not make you a lesser craftman.  Sometimes the power tool makes you a better  craftman, due to more precision cuting, drilling etc. Photoshop is the same, if it is used properly, it can do wonder.
If you want to be a purist, that is another  situation.  For color, you should only shoot slides and develope them  yourself. Then you can clain that is close to be 100% of your own creation, except the slide film. No cropping, no burning, no dodging, no adjustment in contrast and explosure. For black and white, you should go back to the silver nitride glass plate. You can even making the negative plate  yourself. That is creation and art.

As a pro, a mirrorless camera with an excellent eye level VF that was truly silent would be golden for wedding and theater work.
That is the exact reason why Leica M9 and the  Fujifilm X100 are in my mind.
