Lenses / Re: Advice 5d3, wide angle

I wish I could say "Go for the uber sharp 14-24L", but..  :'(

The 17-40 is rubbish, and the 16-35 is more of a workhorse for photojurnalists. Sharp at the center but lousy edges and corners.

If I were you, I would go for the Zeiss 21mm, or for the 17mm or 24mm TS-E.

Personally, I'm waitng for canon to release a better UWA-zoom for landscapers. I don't care if it is 14-24, 16-35 or 17-40. I just want it to be razor sharp across the whole frame.

+1....razor sharp at f2.8 + IS for handheld slow shooting.
I used to wish that, but then, I woke up.

Now I have all 3 mentioned primes. I bought one every year for the last 3 years.

I think I'd be tempted to get a pano setup that I can use for all my lenses rather than something that is so specific.  A pano setup would also allow one to get an AOV wider than the shift limits of a lens.
+1 That's why although I am aware of the TSE collar I didn't get it. It's much better to spend the money on a generic solution.

Actually, apparently you're supposed to shift the camera, not the lens.
Yes but to do that the lens and NOT the camera must be steady. So the lens has to be fixed to a tripod somehow. In order to do that you need a special Canon TSE Tripod Collar from HARTBLEI.

See: http://www.hartblei.de/en/canon-tse-collar.htm

However, it is very expensive and there is something that is often neglected. If you shift a lot you will reduce the sharpness in one side (if you shift close to lens shift limit). In addition, depending on the aperture it may cause vignetting (although this is less of the problem since a closed aperture will probably be used).

+1.  I am less than impressed with the noise on my 5DIII. I find the 22mpx enough for me, but expected far better low noise performance. Using Topaz denoise doesn't help much either. OTOH the problem is probably behind the Camera.
Cheers

Here is an example 1/4000s, 400mm F5.6 ISO4000, its easy to see in the two squares. Now thats
at ISO4000, so obviously at anything higher its worse. In this case when I tried Topaz denoise
(the example here is the BEFORE state) it worked pretty well.

So, is this too much noise? And its not in the darkest parts

CHeers
Those settings don't make any sense to me... and why is the bird & his wing not frozen at 1/4000?  And not in focus at f/5.6 with a focal length of 400mm?   

I may be wrong, but shooting this at 1/1600th, f/3/2 since it's 400mm focal length, and iso 100 - 400 depending on time of day,  seems like could be a quick and easy solution to take care of all your noise problems, to me anyway...   At ISO 4000, you're just asking for issues IMHO... No offense intended... :)
I like both sharpness and ...noise (It does not seem bad for ISO4000, but that's me). However, is this a screen capture at 100% from DPP? DPP uses the jpg file for high quality view as far as I have found so actually the noise is higher in raw.

If you are willing to pay the astronomical amount that M system costs go for it. But since this is a major invesment maybe you could check for the newly announced Leica's (either type 240 or 220).

I am looking to purchase either the TS-E 17mm or the TS-E 24mm.

I'm greatly leaning towards the 24mm. First, I already have the 14mm L II  for when I need something super wide. Second, I also like the idea of being able to use filters without having to buy into a Corkin or Lee system.

Can anyone with experiences with these two lenses give me any feedback or suggestions?

Thank you in advance!
No matter which of the two you choose you will enjoy the results. Unfortunately you will wish the other one too  ::)

How about a better battery?
OP has already said that the battery was the original one. How better than this?

I would suggest to use a Canon 400mm lens instead: either 400mm f/5.6L or 100-400L IS. But I understand that their price is much higher...

Now, I visualize a Canon executive reading this thread and thinking the following as a possible answer to the OP's question:

By the way, thanks for the reference to high speed SS in conjunction with IS. I remembered I had read it in the past but to tell the truth I had forgotten...

Question - when you need fast SS to freeze action is it better to switch IS off? Does it get in the way? I usually just leave my IS on all the time, should i switch it off if my SS is 1/focal length, crop factor adjusted?

Say you were to shoot a landscape at 1/200s at 24mm (obviously don't need IS) but is is there any reason why I should switch it off? Assume I have no tripod.

At what point does IS have a noticeable effect? Like what is the threshold?

Good questions - I asked the same one some time ago and no one came up with a conclusive answer. My 2 cents for handheld (for tripod turn IS off and mlu on esp. for longer exposure times):

At very high shutter speeds turn IS off because the vibration might decrease iq (also see here: http://www.canonrumors.com/forum/index.php?topic=10781.0). For other higher shutter speeds turn it off unless you require the stabilized viewfinder to track an object or set the af point just where you want it. Another reason for turning off IS when it's not really required is simply that it doesn't wear down that way - Canon doesn't give us a 6 year warranty like Tamron :-o

Personally I think IS is unnecessary @ 1-2 stops faster than 1/(focal lenght * crop factor).

hello,

I turn IS off when I use tripod. You see once I used my 70-200 f/4 L IS in a very steady tripod, mirror lock, 2 sec delay. The speed was 30sec. I got an extremely blurry picture!!! I begun to getting confused, angry, etc when it downed on me to turn IS off. Bingo. Pictures were very sharp afterwards! Then I read at the lens' instructions that IS has to be off when the camera is in B mode. Well it was in Av mode but as the speed was 30sec I guess the instruction was close enough.

5Dc
+1 all the way.  The first iteration of the 5D is still a very viable camera for many people and can be had well south of $1K.  It is what I have now.  While it does not have some of the new whiz bang features of new cameras, those features do not necessarily make better pictures.  Plus, the price on the 5Dc has fully depreciated so even if you want to sell it down the road, you will not have lost much in the transaction.  Oh and I love the large pixel size of the ONLY 12MP sensor; allows for a tighter f stop giving more DOF without diffraction issues.  Really wish Canon would make this camera again with this sensor but with ultrasonic cleaning tech included.  They could do that for $1K cameras new.
Good idea. Especially if you think that with current sensor and microlenses technology the noise of a 12Mpixel camera will be lower than 5D's :)

I wish Canon made a 40/1.8. I'd be all over that. I used to shoot Pentax and their 43/1.9 was my favorite lens ever.
NOW! You reminded me of my first SLR: A Konica Autoreflex TC with 40mm f/1.8

« on: November 24, 2012, 11:44:40 AM »
Errr, hmmm, 6D is a camera with GPS not GPS with a camera...
I'm sorry, I was trying to use humor to give an impression of how long a typical Canon battery might last while using GPS. I should've known not everyone pays attention to smileys. Next time I will use [IRONY]-tags.
You had started saying "Gps is not a real battery hog " so I was not sure. But this thread is for laughing so please feel free to continue humor :)  (Plus, I have forgotten to put a smile too)
