Well done and well explained. I want to learn more. Any link/book you recommend to learn tilt shift?

Here are a few useful articles:

I own a 24 TSE MK II and it is undoubtedly the finest lens I've ever owned/used.  Invaluable for landscapes and architecture.  The 17 TSE is near the top of my "gotta have one" list as well.

Great pano mate! How does it compare to the 5DII? Just a reference point for me. Thanks for the reply.

I own both the 5D2 and 5D3.  I've done some limited long exposure night stuff with the 5D3 (auroras and full moon night for day kinda stuff) with exposures up to 30 seconds.  I've also done a ton of that kind of stuff with the 5D2.  I shoot RAW & convert in DPP or ACR.  Real world, I give the 5D3 a 1 stop advantage in noise (or maybe even slightly more  - using Neat Image anyway - the 5D3 files seem to clean up nicer than the 5D2 files).

Hey guys, check out Dell. I recently got body only from them in stock...


Dell seems to run under the radar but they do carry Canon stuff.  I ordered one when everyone else was out of stock and it arrived in Juneau, Alaska 2 days later.  Not too shabby.

I've got 2 hot pixels I've noticed on my new 5D3.  I haven't used the manual sensor clean trick yet since ACR will normally map them out during RAW conversion.  As for being concerned about having a few hot pixels on a new camera, well, it does kinda suck, especially for the money we're paying, but I guess with 22+ million photosites on the sensor, there's always gonna be some minuscule failure rate.

This is really interesting to me. Has anyone in this forum performed any sort of Light Painting? I've been itching to try but this has me sketched out. Is there a special type of lighting that is recommended for use so the sensor isn't harmed? Are LED's acceptable or will this same problem arise?


LEDs are fine for light painting as are just about anything else - just don't use lasers and point them at your sensor.  (bummer for the OP - hope it works out OK)

Most used:  24-105 f/4 IS
Most incredible: 24 TS-E MK II
Most surprising: 70-200 F/4 IS

Thanks for the tests.  Very interesting.  Any plans on showing results from less extreme pushing, say +2 stops?  That seems like a more reasonable, real world sort of test.  My 5D3 should arrive tomorrow and out of curiosity I'll probably do the same test with a 5D2 & 7D and even a IR converted T3i if it's be useful.

And to the folks who are critical of anyone posting this type of info - some of us are interested in sensor performance pixel peeping and find it informative, whether or not it has any real world relevance.  Personally, if I'm going to drop $3500 on a camera (or even just $100), I want as much info about the camera's performance as possible.  If you don't, well maybe consider just moving on, that way it won't turn into a DPR type debacle.


I have a 24-105 & use it on a 5D2.  It sounds to me like you've got a subpar 24-104.  I think your expectation that  it not be as sharp as your macros is realistic but my version of the lens doesn't suffer from the issues you describe.  I'm expecting a 5D3 in a couple days and I'll certainly be testing the 24-105 on it.  Hopefully the new gapless microlenses & ever so slight bump in MPs haven't combined to accentuate any weaknesses of the 24-105.

Sorry - can't comment on the 24-105 vs 70-300 comparison but I'd be happy to report back on my 5D3 + 24-105 tests.

Lenses / Re: 24-105 or prime lenses on 5D2 ?
« on: April 02, 2012, 06:05:52 PM »
My opinion, as a former "primes only" kinda guy:

I use a 24-105 f/4 IS on my 5D2 as a walk around, do everything sort of lens.  I really love it for that.  Yes, it has some downsides like some distortion (particularly wider than 35mm), vignetting and it's kinda slow at f/4 but man, I find the image quality to be pretty darn good and the IS very useful.  The range is nice too but I do sometimes wish it had a bit more on the long side.   I still have a bunch of primes for special circumstances but the 24-105 is certainly my most used jack of all trades, fun, worry free lens.

Good luck with your decision!

Lenses / Re: 16-35mm II "Loose" - Repair costs?
« on: April 01, 2012, 09:58:43 PM »
Judging from a recent personal experience and from others on the Miranda forums, recently a trip to Canon repair will start at around $200 and go up from there.  They probably won't give you much info over the phone but will send you a quote & request for authorization to make the repair via email when they receive and inspect the lens.  I'm going to be sending an old 300 f/4 IS in tomorrow for a loose focus ring and cleaning/inspection to make sure everything's in spec and I'm braced for a $200 charge.  :o

Good luck!

Yowza!  Thanks for all your hard work!  Very much appreciated.  It's great you used a wide range of focal lengths.  I'm looking forward to downloading some of the files and doing a side by side.


Lenses / Re: Ultra Wide Angle with Full Frame

Certainly was, many thanks for taking the time. I have the 17-40 and MK I TSE 24mm and always use MF + Liveview when doing landscapes so no worries there. Cumbersome aperture selection might niggle me, but I presume you could test out the apertures and notch in your most use (mine would be f/13 or f/14)? Adapter is MK III but no idea on what has improved, certainly not aperture selection by the looks.

I'll wait the year till I see if Canon can respond with a UWA of comparable form. TSE-17mm would be interesting acquisition  :D

Thanks again.

Have you tried a 24 TSE Mk II vs your Mk I?  The MK II is worlds better (I owned a Mk I).  Frankly, now, for architecture and landscapes, I can't imagine going back to a non-TSE lens.  I'd seriously consider a 24 or 17 TSE + 1.4 adapter over the Nikon if you're considering the Nikon, especially if you're used to using TSE lenses and live view.  But yeah, for over all usability, a Canon 14-24-ish f/2.8 equivalent would be very, very cool.

Oooh, I was looking at the Nikon 12-24mm with adapter.... Could you expand on why you did not like the adapter please? Assume you got the 16:9 website one?

Yep, it was the 1st generation 16:9 adapter.  I bought the adapter & eventually rented a 14-24 for a couple weeks with every intention of ending up buying one.  Well, first off, the 14-24 is indeed a rocking lens.  Sharp throughout its range and into its corners, contrasty, built well, etc.  Highly recommended for the right person.  For me, the fact that at that time (it may be different now, I haven't kept up with the Canon to Nikon adapter evolution), you had to pretty much guesstimate what aperture you were using (except wide open and maybe f/8 and fully stopped down) was bothersome.  I also found I unexpectedly missed the ability to AF (it was going to be an all purpose lens, not just a landscape or architecture lens and I kinda suck at fast manual AF).  In the end I decided that for the amount of times I really need or want really wide, I could make do with the Sigma 12-24 Mk I I had at the time and hope they would soon make an improved version, which they did.  Given the cost and slight inconvenience of the 14-24 plus adapter combo, I just couldn't justify the purchase.

Now, my 24 TS-E MK II on the other hand is the best lens I've ever used and I'm now saving for a 17 TSE (but that's another story)

Hope that's useful.

I own both the Mk I & Mk II versions of the Sigma 12-24 I use them on a 5d2.  I've also tested the Nikon 14-24 with  adapter on my 5D2. I also use the amazing 24 TSE MK II.  The Nikon is a terrific lens but ultimately its cost and the necessary use of adapter turned me off.  My sample of the Sigma 12-24 Mk I is pretty good in the center but not so good (e.i. bad) in the corners.  My Mk II version is also good in the center and much, much better in the corners (e.i. very usable).  The MK II does have more distortion than the Mk I but  PTLens deals with it just fine.  Both lenses are contrasty enough and both have a bit of Sigma color to them which I don't mind.  Build quality is pretty good as well.

As far as the "don't settle for anything other than the 16-35 Mk II" sentiment expressed by some, I dunno, if you want *really* wide, 12mm is *a lot* wider than 16mm.  But if you need f/2.8, well then the Sigma would be out of the running. 

Have you considered the Samyang 14 f/2.8?  That gets generally good reviews, especially for its price to performance ratio.
