Lenses / Sigma 14-24mm OS lens at Photokina?
« on: August 14, 2014, 05:41:34 PM »
Oh snap.  Ultrawiders who really want 14mm on a zoom might be happy to see this rumor...

...but I think someone will complain about not having f/2.8 before anyone can say woohoo to a 14-24 lens.

EOS Bodies - For Stills / Fun Arias rant on APS-C vs. FF
« on: July 28, 2014, 06:29:06 PM »

Another APS-C vs. FF rant, this time by Zack Arias:

I'm not remotely foolish enough to stir a debate so much as pass on something that will give the pre-digital-era photographers a smile.

I've had a 24-70 F2.8L I sitting unused since I opted for the 24-70 F/4L IS (which is a joy to use, by the way).  I made up my mind to sell it some time ago.

So I went through one online quoting process with a few folks -- KEH, B&H, Adorama, etc. -- and kept seeing quotes of X and the same lens being sold at the same sites for 1.5X. 

I lack the eBay time to rack up happy customers, and I'm told that eBay is a customer-tilted justice system in which I may be found guilty without a proper trial.

So I am asking:  what is the easiest way to sell lenses that minimizes drama, maximizes simplicity, and doesn't involve me giving it away for nothing. 

Easy question, right?

Annnnnnnd:  Go!

I started a survey on a 7D2 rumor thread, but thought I'd increase my hits by having a standalone posting.

Head here for my simple and fast survey re: displays on the back of DSLR bodies.  I'm trying to segment everyone's take on touch vs. no touch, rigid vs. tilty-swively, etc.
(I did this offsite to get more than one question asked with a multiple checkbox response, that's all)

Everyone can participate once, and then repeating the link should show the results.  It's interesting so far, but I'd like more responses if you have 90-120 seconds to give.  It's fast.


Lenses / 16-35 F/4L IS -- Canon registration, ACR profiles, etc.
« on: July 14, 2014, 12:31:58 PM »

I just got the new 16-35 F/4L IS, and I had two questions:

  • When I tried to register it with Canon, there was no option for this lens (or the new EF-S 10-18 IS lens either) under UWA zooms.  I checked to see if it was misfiled, but I can't find it.  I'll assume Canon just hasn't updated their website yet.  From past lens release experience, how long does this usually take?
  • Is there any estimate on the lead time for an ACR update with lens correction profiles included for this lens? I notice there was an update in June but this lens was not included.

Software & Accessories / To filter or not to filter
« on: July 14, 2014, 12:23:18 PM »

just curious, what's your preference on using the front filter threads on your current lenses?

For the sake of this poll, let's assume that:

  • We are not talking about landscape / square / ND grad sort of hardware as that confounds the question a bit.  If you have a lens you only use that hardware with, please discard it from consideration with your answer.  We're looking for general shooting here.
  • We are only talking about lenses that natively allow front filtering without special hardware or a third party solution. So I am not talking about superteles with rear-filtering, UWA lenses with outrigger attachments, etc.

Please note that I am not trying to stoke the ongoing sometimes well-behaved / sometimes not well-behaved debate on this [cough] polarizing topic.  I am just looking to establish a baseline on filter practices this forum uses.

EOS Bodies / Eos7D mk2, How EXCITED will you be if . . .?
« on: July 07, 2014, 10:50:24 AM »

I'd thought we'd start the week looking forward to something.  What features / performance levels would get you excited about the 7D2? 

I want a positive statement from you about what would legitimately fire you up to own a 7D2.   No snarky "APS-C is not for me so I'll say 'A 50 MP FF sensor', ha ha" stuff.  Seriously, what would get you excited when the 7D2 announcement comes?

- A

Disclaimer:  I'm not trying poke fun at Ivan's original thread so much as build some excitement around a release.  Mondays need positive thoughts because they are, in fact, Mondays.

Landscape folks,

I just ran a quick vignetting test with a new 16-35 F/4L IS with Lee Filter setup attached just now.


  • Used a FF rig, a 5D3 in my case.
  • Shot at F/9 perhaps 18" away from a large white wall.  Confirmed focus once at beginning of series and then switched to MF for all shots so the lens wouldn't hunt on the bare white wall.
  • Used a Lee 77 wide angle adaptor ring directly on the lens' filter threads
  • Attached a 2-slot Foundation Kit holder with the 105mm CPL ring screwed on the front.
  • Ran a series with nothing in the Holder, and then ran it again with the 105 CPL attached.
  • Walked the FL from 16-24 in small manual increments (the gap in the ring is relatively small in between 16 - 20 and 20 - 24, so it was not an exact science.)
  • Cable release, tripod, LV, etc.
  • The CPL was a 105mm B+W Kaesemann filter (BWKCPMC105 at B&H)
  • The camera did not have peripheral illumination enabled, but I don't think it would have mattered as (a) there is no lens profile recognized by my 5D3 and (b) the type of vignetting this issue creates is a black and white hard obstruction.
  • Pulled Focal Length value from the EXIF from a Mac OS Command-I (info) pull.  No idea if there is a more exact way to get the value.

Results with the CPL ring on a two-slot Lee holder but NO CPL in place:

16mm - 24mm:  Clean.  No vignetting. 

Results with the CPL ring on a two-slot Lee holder and the CPL was in place:

16mm: Vignettes considerably.  Expected.
17mm: Vignettes.
18mm: Vignettes slightly.  Cloning/editing this out is only a small chore at this point.
19mm: Vignettes the smallest possible amount.  A trivial fix in PS or whatever you use.
20mm - 24mm: Clean.  No vignetting.

Pleasantly surprised.  I thought I'd need to painstakingly disassemble my Holder down to a 'two options' variety (one slot with CPL, two slots with no CPL ring, etc.) to use this holder at all with the 16-35.  But as my holder stands, I can shoot with 2 slots (no CPL) at 16mm and all three starting at 20mm.  I love it. 

That the only wildcards here that might differ on your FF rig with this lens are (definitely) the thickness of your CPL's front ring and (possibly) the version of your Lee Holder.  Lee is known to have snuck in weird versions over the years that are ever-so-slightly different.

Hope this is helpful to you!

Lenses / Canon EF 16-35 F/4L IS -- Reviews are trickling in...
« on: June 26, 2014, 02:34:50 PM »
And Bryan Carnathan at TDP is first:

Please post links to any reviews that you see on this thread.  My rental of this lens just arrived -- can't wait to put it through it's paces this weekend.

Lenses / EF 16-35 F/4L IS corner samples & comparison
« on: June 22, 2014, 03:26:21 PM »

From Phil Aynsley at, we have some corner comparisons of the new EF 16-35 F/4L IS against the EF 16-35 F/2.8L II and the TS-E 17mm F/4L:

Hardly a comprehensive look, but it's clearly showing some corner improvement over prior lenses.

Hey all,

PZ finally got to testing the Sigma 50 Art, but for some odd reason their first review is on APS-C and not FF.  I expect that to be remedied soon, but here are the crop results:

Shockingly, they found it to not suck to a very high degree.  Stellar resolution numbers on their test rig (a 50D, I believe).

They did flag a small focus shift when stopping down, though -- that's the first I've heard of this.

But FYI on another highly satisfied reviewer with the 50 Art.

Lenses / New EF 16-35mm F/4L IS lens hands-on video and still samples
« on: June 11, 2014, 12:16:02 PM »

FYI for those eager to see the new 16-35 F/4L IS -- a short hands-on video and some sample shots are here:

Most important thing I learned (see 1:30 in the video):

It's internal zooming/focusing if you define that as nothing protrudes past the filter ring of the lens.  But there is no front element that covers the entire lens, so that zooming motion leaves a sliding surface that is exposed to the elements.  If you've shot a 50L, the relationship is similar (but obviously being a prime, that sliding is a focusing motion and not a zooming motion). 

For me, that's technically internal zooming/focusing for length but not for access to dust/moisture;  with (say) a 70-200 lens, that zooming motion is entirely captured behind a front element, which I have to say gives me a little more peace of mind when shooting in the elements.

Yes, normally I would UV or CPL this lens for handheld use anyway, but with an ND grad setup that you use right on the lens, this could be a potential for dust/moisture to get into the lens.  Seaside landscape shooters -- do you care about this?  (I never bought an ultrawide since I moved to FF, so I don't know if this is similar to the 16-35 F/2.8L or 17-40 F/4L and you've been coping with this limitation for a while anyway...)

He also goes on to say IS doesn't do much in wide angles... for video.  [Cue drum fill.]  If it gives me 3-4 more stops of handholdability in low light for my stills, this lens will be golden IMHO.

All, I am building a camera cabinet out of some CD/DVD storage filing cabinets:

So it's foam time now!

I'm of two minds with this, and I'd like everyone's thoughts:

1) I love camera bags' modular divider systems as I can rearrange things easily, but foaming and velcro-ing four 34" x 20" trays will take serious time.  I've seen rectangular foam inserts for satchel bags, but nothing this big -- Is anyone aware of a shortcut or pre-set kit that might help?

2) I also have seen folks get Pick n Pluck foam ( to build specialized cutouts that tightly hug gear.  As impressive as this looks, I don't think I need that level of protection for a home cabinet that will not be on wheels.   I'm also worried that Pick n Pluck is a one-time deal and I often like to rearrange the organization of my gear.  But talk me down -- has anyone used it?  What has your experience been?

3) Is there another option that might work?

Also, I was thinking a relatively thin (1/4") neoprene/foam mat on the floor of each tray -- one big sheet across the entire shelf that the dividers would subsequently go on top of.  Can people recommend a good material for this?  (I know that seems like very little bottom padding, but the real threat to the gear is side to side motion with a jarring opening or closing, right?) 


Software & Accessories / Recommended storage for gear in your home
« on: June 01, 2014, 05:13:31 PM »

I'm at the point where I can't get all my gear into my biggest bag any longer, I'm always playing the 'bag game' before each shoot.  This entails shuffling my gear amongst my various bags until I have what I need in one bag and then I'm off.  Further, everything is tucked away super efficiently, but that's a pain to move from one bag to the next.

So rather than buying a bigger bag, I thought I'd get a large storage solution for my home.

I am looking for a home storage solution that:
  • Will sit in a dedicated place in my office as if it were a piece of furniture or office storage.
  • Requires no major unstacking, lifting out of dividers, deconstruction, etc. to get gear out.  My office is fairly crowded and I don't want to unstack a few tubs or cases to get at a particular piece of gear.
  • Note:  this storage solution will never been in sunny, rainy, dusty or humid environments -- it will 100% of the time be indoors.

I'm basically looking for a large tool box for camera gear.  I have in my mind something not unlike a Craftsman tool chest that has numerous drawers to slide out and access various lenses, accessories, etc.

Pelican immediately came to mind, but I'm generally seeing 'tackle boxes'/foot-locker designs and not a quick-access set of drawers like in an office filing cabinet.

Have any recommendations that might fit the bill?


EOS Bodies / Canon + Fuji Mirrorless Rumor?
« on: May 23, 2014, 12:20:38 PM »
This very site posted this...

...then took down the link from the main page and the forum link to discussion on it.

Did someone ask them to take it down?   ::) 

(I highly doubt it, but I thought I'd put it out there.  Whoever conjured up this decidedly wild rumor to CR1 status is undoubtedly high-fiving him/herself right now.)
