PowerShot Cameras / Re: Large Sensor PowerShot? [CR1]
« on: June 27, 2011, 02:08:55 PM »
Now, if we're talking about the 5D2 FF sensor inside a Canon P or 7 body with Leica M-mount...  ;D

That will be my dream camera. I have a few Lieca lenses waiting for it. The M9 is too expensive for me due to shift of priority.

Lenses / Re: Why did Canon make EF-S lenses
« on: June 11, 2011, 11:22:19 AM »
The main reason to make EF-S lens is to take the advantage of the smaller mirror in the APS-C sensor body(The rear lens element can get into the camera body deeper) and  smaller image circle. These will make the design of wide angle lnes (or zoom) easier. As for pricing, that is another story.  Canon can sacrifice quality to make it cheap (as in the kit lenses)or make it good and expensive (17-55 f2.8). I personally think taht Cnnon is smart to make the EF-S lens, especially the 10-22 and the 17-55 f2.8.

EOS Bodies / Re: 36x36 mm cmos sensor
« on: June 11, 2011, 11:11:09 AM »
Dont know why people are saying that you cant have a 36x36 sensor. Now it is 36x24 , and a lens is round.. so i dont see the problem here.
I want a square one, and i want it bad

There will not be enough room for the movement of the reflex mirror. The existing EF lens will just clear the movement of the mirror for a 24mm high sensor. now you are asking another 12mm extra.

Skip the mirror and make an electronic one, That will also elimiinate problem wioth the mirrorshake
There is only ONE TS-E lens will give you 36 X36 mm coverage. Do you think that Canon will make a camera that is based on ONE lens only and with the slow AF and view finder of a point and shoot. Will you buy this camera.? The standard coverage of FE lens is 30.4 MM square.

EOS Bodies / Re: Different camera numbers internationally - why?
« on: June 11, 2011, 12:27:39 AM »
The naming system used in U.S. is different from the rest of the world is due to the Importer of Canon in U.S. wants to identify their own imported product when it dealss with the warranty. Canon U.S.A. will only honor the warranty of the product that is imported by them ONLY. If you buy a camera outside of U.S. and needs warranty work, you need to pay for the total repair cost. By looking at the product number, Canon U.S.A. known whether it is their imported product or not.

Given that the 1.8 & 1.4 are from the pre-digital 90's, how about making the 1.4 into the base EF lens, adding the IS and improving the overall quality, selling that at double the price, but then making the 1.8 into a pure EF-S lens, knock it down to 31mm to suit the 90% of Canon bodies users (1.6x crop), add IS, add wider focus ring, add FTM and sell it for about 2-2.5x the current price.  Bingo !  The beginnings of a EF-S range of primes.
Excellent idea. Hope that Canon is listening.

Lenses / Re: Lens cap solution?
« on: June 07, 2011, 01:19:40 PM »

I seem to be the only person on the planet who like the Canon-caps much better than the other pinch-in-the-middel versions. Those often popped out of my grip and bounced off the front element. but the Canon caps I simply take on and off edge first, much easier to grip the whole cap side by side, than a small awkard grip in the middle....

I totally agree with you. When it bounce of the front element, it may scratch the lens. Also depends on the lens design, the center grip cap may have a chance to scratch the front element of the lens, especially the wide angle lenses( The mechanism of the center grip can lamost be flush with the bottom of the cap)

Try this. Not in production yet, but seems like a good solution. Thought of this thread the moment I saw it.

http://www.kickstarter.com/projects/293194835/camera-lens-cap-holder
I can foresee three potential problem with this product
1. You need multiple cap holder to be attached to the camera strap if you are using multiple lenses with differeent cap size.
2. With multple holder attached to the strap, the camera strap may be akward to be used.
3. With the lens cap dangling on the strap, It will have more chance to come loose without the photographer even knowing it.

I doubt it.  The 50/1.2L is not that old (released in 2007), and was itself an update of sorts, from the 50mm f/1.0L (released in 1989, and still shows up on the used market occasionally for $3-4K).  The other two current 50mm standard primes are from the early 90's.

Why did you tell me about this lens...you just cost me an extra $3000.  Thanks.  :)

I did not know the f/1.0 existed, but for the night time pictures I take, it might be the right lens.

Good job no one mentioned the f/.95 then!
f/ 0.95 is for Canon body with Leica screw mount

Camera equipment is very "personal". I suggest you to try out your self. See how it fits in your hand,how does the controls falls at your finger tip. how do do you like the manu/ etc. You cannot not go wrong with either band. Let your feeling of the handling and your buget be your guide. Also just buy the minimum amount of lens that you need and buy more lens until you really liket he camera body that you have. I bought my 20D 6 yeras ago with only one lens 17-40mm f4.0. This will fit 90% plus o fmy need. Later, I bought a used 35-135mm USM for very occational use . Year and a half ago my 20D died. Instead getting a 7D I got myself a used 40D with only 4K activation. I have put on ore than 40K shots on it on all continents. A s for support, I got all the free software and firmware update  and free technical advice from Canon when I need it. No complain here.

" 19 point AF system, 3 cross-type points"
That is a few steps backward from the 7D. 7D is ALL 19 points cross.

EOS Bodies / Re: What do you recommend for beginner?
« on: April 14, 2011, 11:09:58 AM »
However, there's one drawback: he's a Nikon shooter! That's blasephemy! :P

I agree, that was the biggest letdown..  :D But, seriously... Good books, easily accessible. Just the other night I needed to quickly refresh what settings I needed to use when taking a shot of the moon and it took me less than a minute and I was ready. I did a comparison to one of the 500 page-monster books I have, took me about 10 minutes to find the location and the it rambled on about a bunch of technicalities, all I wanted was a suggested shutter and aperture.  :D
The monster-book is great in explaining the actual workings of stuff, but for quickly finding suggested settings it is not the right place.
I can recommend a cheap, concise and GOOD book. "National Geographic Photographer's Field Guide". ($4.95, at least used to be). with pictures, examples etc. It is 120 pages,  4' X 8" fits into any coat pocket.

EOS Bodies / Re: Stronger body?
« on: April 12, 2011, 10:02:48 PM »
This has been brought up before.  It's at your own risk of course, but there are tutorials online on how to either dissemble the camera and clean the contacts, or very carefully tilt the camera the right way and pour pure alcohol up the battery compartment (alcohol cannot have water or components can rust).  I haven't ever done either, but the logic is solid.  Can't say that I would do it though.  I'll have to decide when I run into that problem.

I see how to fix it (at you own risk) in You tube. My point is if the shutter release burtton fails the rugged metal body becomes aboat anchore. So why there is a lot of people on this site insist on metal boby or nothing??

It's cause of this that I'm not a bit worried about rugness.

I take good care of my cameras, they can take allot of abuse.

Maybe a rugged camera would take more of a beating or survive a harsher accident, but prevention is the best ruggedness.
How do we prevent the shutter release button failure?? It is a commonly failure item before anything elses in the 20D,30D 40D 50D etc. They all have rugged metal body, but the shutter button failure will cost US$250 to be fixed. I do no think that I will spend that kind of money on a 3 years old DSLR.

EOS Bodies / Re: The Truth about Microadjust
« on: April 12, 2011, 12:26:17 PM »
I mean think about it...60d doesn't really compete very well with D7000 and Canon has a big hole in their pricing structure between the 60d and the 7d. You'd think they'd just add a couple of firmware changes for the crop zoom and microfocus adjust, kick the price up a couple of hundred bucks and call it a 60d+. They'd sell the daylights out of it and why care if it canibalizes 60d since it's the same exact hardware, so the amoritization of development/production ramp up costs are unchanged? IMO it wouldn't affect 7d since people who really need 8fps, more sophisitcated focus, better sealing, etc won't flex down to something that doesn't have those features.
Totally agree. It is a VERY STUPID move for Canon to take away the micro adjustment from 60D. In fact, it should be a standard issue on ALL Canon DSLR including the Rebels.
