Lenses / Re: A small walkabout lens - lay it on me!
« on: June 04, 2012, 02:47:22 AM »
How about the old EF 24mm f/2.8?  It's small, decently sharp, and reasonably priced. However, it doesn't have usm, so it's got noisy AF and it's built like the 50 1.8.  If you don't mind waiting, and paying significantly more, the new 24mm f/2.8 IS will probably be much better and still be small enough for you.

Diffraction is a lens property, and it is the same for a given lens, no matter what body you attach. 
 
A High MP body has better resolution and can see diffraction better, but it is not any more or less.

Actually diffraction has a lot to do with the body (copied and pasted from the-digital-picture.com):

I guess you misunderstood a bit.
It says that the higher the pixel density, the sooner you reach the point in which diffraction takes its toll. It's the same as when a not-so-sharp lens looks acceptable on a 10MP camera, awful on a 18MP one.
This doesn't make diffraction a body property as much as it doesn't make it sharpness.

Potayto-potaahto.  Yes, technically, diffraction is a lens property.  But...it's awfully hard to use a lens for taking pictures all by itself, without a camera attached.  So, like sharpness, diffraction is effectively a property of an imaging system - lens plus camera.

I stand corrected.  ;D  I guess I did misinterpret that a bit, however I think Neuro summed it up perfectly.

EOS Bodies / Re: Odds & Ends - Mirrorless [CR1]
« on: June 02, 2012, 01:36:20 AM »
It will be interesting to see what Canon can do (or will do) with the mirrorless.  There are so many suggestion (read it s demand) in this site: smaller size, reasonable priced, BIG sensor, small zooms etc. Unfortunately, they mutually exclusive. I am interested in seeing how fast is the AF or does it comes with MF and aview finder ( like the M9)?

The specs are not mutually exclusive:

1. SIZE - no problem
"FF" (36x24mm) can be packaged in a very compact and very high-quality camera without any problem.
example: 124.5 x 77.5 x 32 millimeters, sturdy metal body, weight only 13.405 oz./380.1g with batteries
http://www.cameraquest.com/cle.htm

2. LENS SIZE - no big problem
just look at M-mount lenses not only from Leica but also from Voigtlander and other manufacturers. Even a decent f/4 kit-zoom  could be made very compact and with decent optical quality.  As a matter of fact, no need to develop a new proprietary mount. Just take the patent-expired Leica M-mount and electrify it, using Canon pin layout and mountr-lens protocol. It would be backwards compatible with M-mount lenses  w/ manual focusing.

3. FAST and 100% ACCURATE AF - no problem
Just take the approach of the Nikon 1 hybrid AF sized to FF. Take the 5D 3 sensor, take 10.000 sensels out of it for in-sensor-plane Phase-Detect AF for ultrafast stage 1 "pre-focusing" and then hand over for stage 2: DIGIC 5+ powered, fast and 100% accurate Contrast AF. All back-/frontfocus issues with any lens will disappear. No need for microfocus-adjustment. 

4. VIEWFINDER - no big problem
Take the Fuji X1-Pro approach and make it REALLY RIGHT. Take the best available 3 Megapixel OLED plus parallax-corrected optical viewfinder. Users decide, whether they want to use optical, electronic or combination in a specific situation.

5. PRICE - no problem
same sensor, DIGIC, electronics and many other components from 5D 3 but minus the entire mirrorbox assembly (demanding very minute alignment = labor intensive) and minus prism. Therefore price should be somehat less, lets say 3 grand USD / Euro for starters.

Now, if I can think of this camera, Canon should be able to figure it out too and build it. :-)


Take my money right now.

Interesting that recent cameras are getting defraction earlier than older models.

Diffraction is a lens property, and it is the same for a given lens, no matter what body you attach. 
 
A High MP body has better resolution and can see diffraction better, but it is not any more or less.

Actually diffraction has a lot to do with the body (copied and pasted from the-digital-picture.com):

* DLA (Diffraction Limited Aperture) is the result of a mathematical formula that approximates the aperture where diffraction begins to visibly affect image sharpness at the pixel level. Diffraction at the DLA is only barely visible when viewed at full-size (100%, 1 pixel = 1 pixel) on a display or output to a very large print. As sensor pixel density increases, the narrowest aperture we can use to get perfectly pixel sharp images gets wider.

DLA does not mean that narrower apertures should not be used - it is simply the point where image sharpness begins to be compromised for increased DOF and longer exposures. And, higher resolution sensors generally continue to deliver more detail well beyond the DLA than lower resolution sensors - until the "Diffraction Cutoff Frequency" is reached (a much narrower aperture). The progression from sharp the soft is not an abrupt one - and the change from immediately prior models to new models is usually not dramatic.


He lists the DLAs of many Canon DSLRs in each of his reviews for comparisons.

5D MK III Sample Images / Re: 5d MKIII with 24-70 I

Great shots! Really like the car shots!

Briansquibb, being new posting here I don't know how to incorporate your question in my reply yet. Motorbiking, I currently live in Southeast Asia, have been on and off for the last nine years. So just motorbiking travelling around the region here. The views and adventures gets more in focus than the actual biking as such.

is it an sony Alpha 900 on budget?...maybe they are repackaging the unsold a900as nikon d600


They probably just turned the "a" into a "d" and flipped the 9 upside down. Voila!   ;)

EOS Bodies / Re: DPReview 5D3 review out
« on: May 23, 2012, 03:09:19 AM »
I find it weird that when using the camera comparison, the 5d mkII is rated way better in video mode than the mkIII.  I was under the impression that the mkIII is a step up in every way from the mkII in video. They also gave the mkII the nod for raw and jpeg image quality, as well as the exact same scores for build and handling, which contradicts their own review.  Seems weird to me.

EOS Bodies - For Stills / Re: 5D II/24-70L II OR 5D III/24-70L
« on: May 17, 2012, 03:41:36 AM »
Well I shoot a little bit of everything (not very helpful I know). Probably landscapes, and people mostly.  Situations where I'd need the nicer autofocus don't happen too often, but when they do, it'd be nice to have better autofocus than I'm used to in my T1i. 

Another reason for the 24-70 is because it can focus so closely I might be able to convince myself that I don't need a macro down the road  ;)   

The 16-35/5D III combo would be pretty nice, but probably too wide to hold me over while I saved up for another good zoom. Plus I'm sure 24mm is more than wide enough for my tastes on full frame.  And the 24-105 is another possibility, but that 2.8 aperture is really appealing for the shallower DOF  ;D

Well that's exactly my problem haha.  It's kind of a toss up right now.  I guess I'll just wait and decide when the 24-70 II comes out :-\

Well I've shot with the 17-55 f2.8 and love it's range.  I could live with just that range, so the 24-70 seems like a perfect fit for me.  I plan on adding a few primes over time, but the 24-70 would be all I need for a while. The 16-35 and 70-200 combo doesn't seem that bad though either haha.

EOS Bodies - For Stills / 5D II/24-70L II OR 5D III/24-70L
« on: May 16, 2012, 11:15:28 PM »
I've been saving for a while now to upgrade my T1i and ef-s lenses to full frame, and will have a budget around $4k to work with.  I'm just looking for some opinions on which combo to go with: 5d II and the new 24-70L II or the 5d III and the original 24-70L.

Image quality of the combo, and features/handling are my two main concerns. If the image quality of the original 24-70L plus the newer 5d III is good enough then all the extra features the 5d III offers will be great.  If the performance of the 24-70L II lives up to the expectations and blows the original out of the water, then I could certainly justify getting the 5d II and the newer lens. 

Everybody always says to spend the money on glass, which is why I'm coming to the CR forums for help.  Which way would you go and why?  Thanks for any input  ;D

I hope this means their cost-saving efforts will trickle down to the consumer, but probably not.
