Lenses / Re: What do you do with lens cases?
« on: July 25, 2014, 03:45:16 PM »
i was hoping to find a bunch of creative alternative uses for the mostly unhelpful canon lens pouches, given the title  :P

but since i'm here...

in general i use the pouches for at home storage, and when i'm out and about, my lenses are usually in a camera bag of one sort or another not in pouches.  if your messenger bag is not specifically photo oriented (ie, no individual padded compartments for various pieces of equipment) i would suggest some lens wraps as the snuggest least bulky way to add a little protection to your gear.  if it is a photo messenger bag, just leave the cases at home.

good luck!

Software & Accessories / Re: Tripod center column - yes or no
« on: July 17, 2014, 03:40:55 PM »
i've always had center columns on my tripods and find them quite useful.  back when i was shooting 4x5 with a sinar, it was on a 4 series gitzo with a geared column which was indispensable. 

just recently i was shooting in a small space and needed the extra height that the center column on my gitzo GT2542L provided, and shot without issue.  i was making 6 second exposures with the 17 tse and stitching together images taken with the lens at full rise, centered and full fall.  i used the 2 second self timer, and there are no issues with softness.

like others have stated, with longer lenses using the center column gets proportionally more problematic, but with wide and normal lenses, i have had no issues, and enjoy the flexibility having a center column provides.

Site Information / CR buggy for anyone else?
« on: March 05, 2014, 10:52:25 AM »
for the past 2 days, when i hit a link under forum topics, i get a message saying that the post has been deleted or is off limits to me. when i go back to the main page, the links are all turned off (unclickable.)  when i reload the page, the links become active again, but they off limits thing still happens.  is anyone else having this issue??

glad it's not just me that's experiencing the weird cr homepage!

hi Zv,

the short answer is yes, that's why the dng converter exists and is free. 

there is a bigger conversation about the advantages of converting to dng, mostly having to do with future proofing your raw files.

best,

Technical Support / Re: 24-70 L II softest at 35mm?
« on: October 28, 2013, 02:25:12 PM »
triggyman - these are from the right side center - not the corner.  corners are all similar, although it's possible that the right side is a little worse than the left side.  stopping down certainly helps some, but again, i'm not expecting the edges and corners to be sharp at f2.8.  i was simply struck with how different 35mm was compared to 24 and 70.

you mention that you returned a copy - but did you exchange it for one that was better?  or just get rid of it?

mt spokane: fair enough.

here are some jpegs that are 100% crops from the center and edge (not even the corner) shot at 24, 35 and 70.  they were shot raw, processed to jpeg in lr with no sharpening, lens corrections, or any other adjustments.

they were all at 2.8 as well.

to me it seems that at 35mm, there is the biggest difference between the center and the edge, and i'm just wondering if others have noticed the middle range to be weakest with this lens.

please note i'm not complaining about a lack of sharpness at the edge when shooting wide open, just trying to get a sense of what others are experiencing.

Technical Support / 24-70 L II softest at 35mm?
« on: October 28, 2013, 12:05:13 PM »
hi all,

i just got a 24-70 L II and while it doesn't have the clicking while zooming problem, it does seem to be noticeably softer at 35mm than at either end of the zoom range, specifically away from the center.  (the center seems fine at all focal lengths.)

does anyone else who owns one of these have a similar experience, or should i consider swapping it out - i still have a week or two left.

thanks!

Lenses / Re: 24-70 II slight clicking sound when zooming
« on: October 23, 2013, 05:47:52 PM »
i just got my 24-70 from b&h also from the $1699 deal.  it has a march '13 date code, and thankfully no clicking while zooming.  just thought i'd add that to the data pool...

Lenses / Re: to TS-E or not to TS-E?
« on: June 21, 2013, 10:18:46 AM »
I have both the 17 and 24II ts-e lenses, and while I certainly agree that to get the most out of them it's best to use the tripod / live view combination, most often I use them hand held.  It takes a bit more patience, but for stationary subjects the results are fairly easy to obtain. (I mostly use shift, only occasionally tilt.)  One thing to note is that when shifting more than about 5mm off center, the in camera meter gets pretty inaccurate.  i often meter and focus first, then shift.  The image below was taken with the 17mm with about 10 mm of shift, handheld.

Third Party Manufacturers / Re: Gitzo Center Column Jammed
« on: April 03, 2013, 12:43:56 PM »
we have a lot of gitzo's where i work, and they do get jammed sometimes.  it's one of the few times that i usually just apply more force - rarely do i recommend that when fixing photo equip.  but you could also try heating the center column knob with a hair dryer for a few minutes, and it might expand enough to loosen up a bit.  good luck!
