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!

Lenses / Re: 15-85 USM Dust inside

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.

Lenses / Re: Lens issues; what replacement options do I have?

My buddy has a 17-40 and he is pretty harsh with it. The color saturation is great, its rugged, and contrasty. He says the weather sealing is great. When I was looking at lenses these were too expensive. I bought a sigma 17-70 2.8-4 OS and kinda wish i got the 17-40L. I do like the IS on my lens, and it is a stop faster on the wide end, and I have alot of fun with it at 17mm with IS on at night. You can get sharp 1/4 second shots. The 17-70 seems to be hit and miss with autofocus being front-focused, but your 7d has AFMA so that is probably not an issue for you.

Canon does nearly everything in house. There is no one sending spec-sheets to sony about their camers so the sensor can be made, almost all of canon's lenses, micro-motors, PCB's, and even a lot of their chips are made in house in Japan. Less Mfg's to leak info, the tighter the circle of "knowing" haha. Canon does seem to sit back, let the competition do their thing, then half a year or so later whomp it. see what the future brings

i vote used 18-55 IS for about 75 bucks, and a 50mm 1.8II for low light. nice combo, nice and light, no P+S will match that

noobs often want a mega super tele zoom, but almost never use it, or use it for something that you could just take a few steps closer to. it is too bad she has the older 18-55 non IS, her oportunities for dim lighting are pretty bad. and the old 18-55 was an awful soft lens. A point and shoot under 250$ will be awful in dim lighting as well however. I might have to jump on the 55-250IS bandwagon

Amazon lets you print a return label right from the site, and will have the new lens on it's way before you are done putting the one you got into a box. I like local and hate big faceless companies, but in a hit-and-miss situation like the sigma's are known for, it might be a good idea. Id own a sigma 30/1.4 if i wasnt thinking about going FF.

EOS Bodies / Re: Shooting leveled landscape pictures
« on: August 22, 2012, 09:50:13 PM »
I have used the 60d in-viewfinder level for landscape and it works well, but shooting up a tall building with the camera almost straight up the level doesnt really work very well. leave a smidge of room and post process, and interpolate to the same resolution if you wanna get fancy , fake people out with your increddible level-osity, haha

It has been humid as the jungle lately here in the new england area. My lens fogs up once the grass starts to get morning dew. Only a fairly warm lens will not condensate on nights like we have been having.

Nice shots! Funny how dragonflys will sometimes appear almost friendly. They often land on me to rest when im out in the yard. Humans know they eat pesky bugs. Maybe they know we know that haha!
