Re: Latest 50D vs 40D noise comparison

The two shots have slightly different focus, which is misleading. The one on the right looks sharper because of better focusing, but the one on the left has slightly lower noise.

Re: Latest 50D vs 40D noise comparison

I did not check which is which but the one on the right is sharper and more contrasty with a tad little more noise.

Well, i do mind!

Thanks for pointing out these samples as they seem very valid to me, lighting being identical, NR off in both camera's etc. etc.

Apart from the micro-adjustment feature I for one cannot justify an upgrade from the 40D to the 50D based on what i've seen so far, honestly I couldnt care less about the better lcd or the extra mp's but thats totally due to personal needs and opinion ofcourse.

So i keep my savings and will proceed saving for a really big improvement just as i made that the top upgrade (priority) anyway, the 500mm F4 will suit the 40D just fine

Not good for the 50D

I for one took a chance and pre-ordered but based on these pics it does not look good, no 1 to 1.5 stop in noise reduction with the 50D, also, I can't see any improvement in the resolution over the 10 mega pixel sensor.

Re: Not good for the 50D

I am thinking of just getting another 40D.. The 50D just doesn't seem like it controls noise a lot better than expected.. O well, there is always the 300 or 400 f/2.8 I can get! (:

pattern noise

The shot on the right definitely has more pattern noise (seen as lines in the shadows.)

Regarding "sharpness" etc.... these are handheld shots and to make any evaluation of whether the smaller pixel pitch has done anything good or bad will be overshadowed by the hand shake.

Re: pattern noise

I see same banding in both...one on the right looks sharper and more contrast, which may enhance the noise. The one on the left isn't as sharp, looks softer.

This doesn't sell the 50D for me. I'd rather buy the 40D and put the extra money towards a better lens.

left is 50d rite is 40d...the whole comparison shows nothing.

that thread is at potn site by a user who took shots in the store...liveview resting on counter.

what good are any of these comparisons? none for my eyes anyhow.

i'll wait for stuff with a little more controlled testing... not down rezing one for comparison.... yes i read that thread hours ago and left it once i saw the downrezing idea.

Ignoring any potential difference in focusing...

I will say the 40D shot stands up better.

Too bad the 50D has that one killer feature: AF micro-adjustment.

Re: Not good for the 50D

Funny, I have been thinking the same thing- to just get another 40D as a second body even though I pre-ordered a 50D. Since all my lenses are spot on, without the ISO 1 stop advantage, the only thing left is the upgraded LCD. Not sure it is worth almost $500 more.

Precisely. AF microadjustment + VGA LCD = $500? /nt

And the shot on the right is 40D...

The shot on the right definitely has more pattern noise (seen as
lines in the shadows.)

as seen here: http://photography-on-the.net/forum/showthread.php?t=573650

Regarding "sharpness" etc.... these are handheld shots and to make
any evaluation of whether the smaller pixel pitch has done anything
good or bad will be overshadowed by the hand shake.

there can be no handshake because the cameras were resting on a counter.

The more aggressive noise reduction can be seen on the 50D shot on the left.

hey...

.... since I don't have time to check out all the links... I missed the point about the counter.... so I guess it becomes a question of AF...

Yes, the 50D has less pattern noise, but also greater NR... pick your poison.

Can't think of why they wouldn't do this...

Very true, very.. I would have loved to have seen a little bit better high IS0 performance in the 50D and possibly a new battery grip to use with the 40D(new firmware or something) also to make it shoot 8 fps. Now we would be talking...

The 50D (left side) was not sharpened after resizing.

Here is what the two shots look like after sharpening was applied (50D only) to get the 50D file looking as sharp as the 40D file. The noise grain structure looks finer on the 50D and "surprisingly" the highlights look better to my eyes (look at "digital ph" against the yellow background). Oh well, much better (read, more carefully controlled) comparisons of RAW files are necessary to find out what is really going on. Come on Amazon, where the heck is my camera?

Nope. Manually focused with live view.
