I know. He has a 5dIII and is asking THIS question.... hmph, wish I had money
What is wrong with that question? Just because he owns 5D MK III does not mean he needs to know every technicality about HDR photography ... there are plenty of accomplished photographers who never use HDR function.

True true. He did say he didnt notice the 1 second shutter speed. He may not have realized that HDR works by combining 3 exposures.

I would much rather see ISO 25 and less, without any loss in highlight range.

I wish we had better acess to very low ISO's as well. I would have a lot of use for ISO 10 for creatuve shooting on brighter days. Even with my ND and polarizing filter on I want a lower ISO often

It is everything I wanted to know, thanks! glad you came through neuro! Too bad, some old cheap lenses could be fun to play with, but not as much fun without a working AF haha.

Lenses / Question about older lenses
« on: August 29, 2012, 09:45:25 PM »
Adorama has a used section I look at now and then, and a lot of the older lenses, like sigma's, say they are for EOS (autofocus) but then say "for film cameras only". I have used a canon 35-80 on my 60d and it worked fine. I know lens coatings are dirrerent and all that jazz. Anyone know why they say "for film SLRS only"?

Lenses / Re: No AF: Broken flexfoil in 18-55mm f/3.5-5.6 IS

the flex-foil is removable right? wonder if canon would sell that piece. I want one of these lenses for the same purpose. I have a 35-80iii I got for 5 bucks at a yardsale(attached to a rebel X) i had to take apart and fix for my trashing-lens but it is not wide enough and too soft :-/

Good to see a supportive wife here! and what a B-day present!

The way the camera changes the amount of light for HDR is through shutter speed, so to get that last over-exposed shot it needs to hold it open longer. Try bringing the EV values closer together, like o,-1,+1, then the shutter speeds would be less obviously apart, like, 50th,100th,25th. Doesnt sound like you have a problem, my 60d does the same thing with AEB, but I have to add them into an HDR image myself later :-P id die for a 5dIII!or II for that matter

Odd, and unfortunate.  I haven't had any problems, AF works normally (except for the AFMA firmware bug) on 10 different lenses, including a 24-105L. 

For some reason, AF fails to work - and I mean completely, it doesn't even try - with my TS-E 24mm II and MP-E 65mm.  I suppose I'll sort that out one of these days...   :P

Ahh neuro, I bet this sence of humor doesn't get understood as well to the general public, but you make this geek laugh

It does kinda sound like live-view was enabled?

Lenses / Re: 15-85 USM Dust inside

Any lens that has extending barrels will get dust. Having a dust-free lens only lasts a few outings

Landscape / Re: 17-40 f4 for lower light vs 16-35 f2.8
« on: August 28, 2012, 12:52:16 PM »
After I bought 5D III, I tested both lenses. The 16-35 II is sharper wide open, and the f/2.8 is nice for handheld low-light shooting. DoF isn't much of an issue with a UWA lens. 

You will need to stop down f8 or so on the 17-40mm, otherwise the corners are pretty mushy when shooting at wide open.

At the end, I bought 16-35 II.

The 17-40 sharpness drops fast at the corners of a FF camera. With APS-C size sensors however the sharpness goes from edge to edge.  And to clear up some confusion, a F/1.2 or 2.8 or f/4 lens ALL set to f/5.6 will be letting in the same amount of light. it is only when they are set to their wide openings (f/1.2 etc...) that they are letting in more light. If you want a sharp landscape, usually around f/6.3-f/8 are sharpest, and in this case the 16-35 wont be letting in any more light than the 17-40. Hope that helps!

use it for a month then check out the amount of dust! Take some test shots, I'm sure you wont notice it. My 28-135 IS USM that I used to have had SOOO much dust in it. Never saw any sign in a picture. that 15-85 is quite a sharp lens, I wouldnt mind one.
