Lenses / Re: 24-70mm lens. Which one?

Actually there is a 1.8/f zoom, the new lens from sigma 18-35mm.  Reviews suggest that it is really something else.
but it is for crop cameras only

So were horse and carriage ;)

How do you print a video?

One frame at a time.  Ba dum tssshhh.   ;)
unless you recorded interlaced. Then you can print half a frame at a time, if you want

Lenses / Re: EF-S 15-85mm f/3.5-5.6 Vs EF 24-105mm f/4 L
« on: October 10, 2013, 02:56:02 PM »
I never used the 24-105 on a crop body, but did use the 15-85 and was very happy with it. I know there are happy 7d with 24-105 users out there, some of them complement the combination with a EF-S 10-22 or another UWA, because 24mm on your 7d is not very wide. I terms of Image quality, don't expect the 24-105 to be any better than the 15-85. Since you have the 15-85 already, I would just stick with it.

What is(are) the exact reason(s) why you are considering the change?

You are using both your feet to stand on the chains.  Therefore, it is a bipod, not a no-pod.
and the thing itself doesn't have feet, so no-pod is correct. We are the bi-pod :) But who cares really, especially if it works?

interesting results, thanks for sharing!

The Sigma is much more artistic :)

Speedlites, Printers, Accessories / Re: Choosing the right tripod
« on: September 25, 2013, 07:27:37 PM »
One thing to look out for is the height of the tripod.  No matter how good a tripod is built, if its not tall enough to use without cranking up the center column, it will not be stable enough for long exposures, and it will be susceptible to blowing over in the wind.  Hanging a camera bag of gear on the under hook (get one with a underhook) can prevent blowing over.
Good point on the height. The aforementioned Sirui M-3004 and M-3204 (the latter is the CF version) are tall enough for me (191cm or 6'2'') without center column extended

All this power and why can't we have an M mode?
Aren't there camera apps that have manual mode?

Lenses / Re: Review: Canon EOS 70D

I do find it a little sad that the buffer on the 70D isnt as good as the 60D (40/15 vs 60/18 I believe), despite having better processors, etc. The frame rate and AF jump are nice, which would be made even better with a bigger buffer. But that's a minor complaint
I don't think the buffer on the 70 is worse, it is actually better. Or one could say it depends how you look at it :) Fills up after less frames, but has higher capacity. But because of the higher frame rate, data is arriving much faster (over a shorter period of time), and a lesser portion of the data can be written to the card in that shorter period of time.

I hate my Iphone 5 and unfortunately, I don't have much of a choice beside just waiting for another generation. Apple trapped me here years ago with the 3G, Now it's too much trouble to switch and repay for alot of my stuff. Good strategy apple.
What's wrong with it? I was considering upgrading to the 5...

Lenses / Re: Did I get a bad copy of the EF-S 17-55 f2.8?
« on: September 11, 2013, 09:10:39 AM »

DOF based on aperture is just an approximation. There is a well known Zeiss document$file/cln35_bokeh_en.pdf

about DOF and bokeh, where they explain and actually measure the loss of sharpness away from the focal plane for different lenses, see p. 23 and 35
Looks like an interesting read, thanks for the link

To the OP: the crops you posted look a bit dissapointing, but at f/5.6 or higher most lenses become more and more equal in terms of sharpness.

Here are two links from TDP with comparisons, maybe that helps to see if your copy falls into the expected range:
