135L vs 85L vs 70-200L II

Interested in owners of a combo of some of these lens

I had a 85L II and sold it as I found keeper rate on 5d mk2 was low with focus issues.
But loved the 1.2 effect when it worked
To me, the 70-200 II was more useable and I think it's a super lens

But since buying the 5d mk3 I'm having a little seller remorse as I feel it would be more useable now.

I've also heard the 135 has a unique look but never used it

So my questions are
Is the 85 better on 5d3 ?
Does 135 produce something better than 70-200 II ?

I do some weddings, but mostly i shoot for personal or portrait. Perhaps the more subtle 135 would allow me a little more street

Is there a good reason to own a combination of these lens, or are they too similar to justify high prices?

Depth of Field calculators

Anybody have any experience using one of the DOF calculators for iPhone/iPad ? Such as the "Simple DOF Calculator" or "Depth of Field calculator" in the iTunes App Store ? I know I can manually preview DOF in camera, but it would be nice to review a calculated field prior to selecting lens and/or apertures.....

Also, I assume I have to convert the focal length of a lens on my APS-C camera to the effective length when inputting data to a calculator (such as inputting 80mm as focal length for a 50mm lens on a 1.6 crop factor camera)?

Thanks for any comments/opinions.

Canon EF 35mm f/2L IS Review from the Digital Picture

Bryan Carnethan has a very favorable review of the new 35mm f/2 IS up now:

http://www.the-digital-picture.com/Reviews/Canon-EF-35mm-f-2-IS-USM-Lens-Review.aspx

Most interesting is that he concludes that the bokeh is smoother on it than either its predecessor, the 35L, and the new Sigma (which he makes second).

The biggest advantages of this optic over the Sigma:

1) The very effective IS (he calls this the most handholdable full frame lens available), particularly for video purposes.

2) Much smaller size and weight.

3) AF is (according to Brian) amongst the quietest he has heard (which definitely sets it apart from the old 35mm f/2).

Biggest downsides (vs. Sigma)

1) Slower aperture

2) Slightly lower sharpness.

I'd really love to see a head a to head comparison between the two lenses. I will probably add one of them to my kit within the next year, and I'd love to see them compared.

Question about variable aperture

Not afraid to ask stupid questions as it's the best way to learn and normally people on this forum will give informed answers.

My question is around variable aperture in lenses. Why do lenses with variable as opposed to fixed aperture cost less? Is it a mechanicel explanation to it? I can see that more advanced optics will cost more with more glass going into the lens, but don't understand the dynamics behind aperture.

I'm in the IT business and have been for many years, hardware related features sometimes costs more to develop and produce and somteimes it is simply down to charging more for better functionality - higher margins from customers prepared to pay premium for higher performance.

I would be happy to understand more about this.

thanks in advance

Canon 24-70 ii - another superlative

Yet another ringing endorsement on the new Canon zoom. I upgraded with a touch of uncertainty after selling off my old version simply on account of not using it much - but since that time, I was finding myself increasingly zooming to 40 whilst using my 17-40 as a street walk-around/night lens and so the new 24-70 seemed a good fit.

After a night of shooting tonight in the city, I am astounded at the sharpness, clarity and sense of dimensionality inherent in the images. The starbursts are so punchy and spikey - they resemble F11 or higher (I shoot usually at F8) and are clean and virtually flare free.

People may complain about the price but I tend to see why now - with a slightly heavy heart I agree this lens is worth every $$ - and as a tripod or day walkaround architectural lens, it's superb. I'm still not convinced about it as a people/portrait lens - for that I prefer the primes - but for everything else, it's fantastic.

Tips needed for shooting in the cold

Hello CR Folks,

I'm off on a ski trip shortly. I wasn't planning on skiiing, but I do intend to shoot a lot all over the mountain.
Was planning on leaving the non-L glass at home and sticking with my weather sealed 24-70 F/2.8L I and 70-200 F/2.8L IS II on my 5D3. Both lenses are filtered for weather sealing.

Temperatures will be in the 10s-40s (F). Can you guys give me the do's and don'ts of shooting in the cold? Assume I'm outside for a few hours at a time.

Sorry for the rookie question, but all my snow shooting to date has been 5-10 minutes at a time so I didn't take any special precautions. So as I rarely shoot in the very cold, assume I know nothing about it.

So...

  • Should I never change the lens when out in the cold?
  • Should I never change a filter when I'm out in the cold? (I often yank the UV in favor of a CPL depending on the sky, what I'm shooting, etc.)
  • I seem to recall there was a concern bringing in cold and/or externally damp gear into a warm place (like my cabin) -- something associated with condensation inside the lens as it equilibrates to temperature. Should I ziplock bag my gear before I bring it into a warm indoors location?
  • My tripod is carbon fiber, and it will most certainly get cold and wet. Do I need to take any precautions to using it in such conditions?

I appreciate your guidance.

24-105L vs 24-70L -best lens for commercial work...discuss & help my options

Ok wondering if this might be slightly controversial to some purists and F2.8 or less fanatics..

I would like to hear from other working commercial pros, no offence to everyone here who shoots beautiful shots wide open of models, wedding or family all the time.

Currently looking to get a / some new lens, why? the 24-105 is good but not great. Sharpness is ok (poor at 24 and 105 and soft at F4, from F5.6-11 its great and F14 onwards is very soft. Having F4 is ok but 2.8 or less would be much better to have, and generally the Out Of Focusness of lens is smoothish and pleasing, generally nicer than my 50 1.4- comparatively F4-8, but obviously you cant get anywhere near the 50 at F2 and similarly nowhere near as nice as my 135L.

I'm on my second one now as last broke too many times and the focus was out finally, but my new copy doesn't seem quite as sharp as previous when it was new. So I'm now looking for options to work with my type of work.
I use a 5D mkIII if thats relative and shoot tethered to Capture One Pro 95% of the time, and 75% on a tripod too.

Now I don't want 100 replies saying the 85 1.2L is the best.. I know I use one occasionally when needed that look. Or the 50 1.2. I may well get the 50 1.2 soon but the lack of close focus is putting me off slightly.

Firstly I don't get the chance to shoot much fully wide open on jobs, I do commercial work (advertising, corporate, people, lifestyle, still life and some architecture all with a lot of retouching) - which dictates what needs to be in the shot and how it will look. And normally you have to show some background OOF but not completely melting away to show a sense of reference to the location/background & person in foreground or product photography that has to be fairly sharp for the most part.

I use studio lighting most of the time and to me the main quality in photography is in the lighting and knowing how to light a scene really well or control daylight. IMHO this does much more than buying a really expensive lens.. I'd rather always buy more lights and modifiers than lens.

I never really need to go over my 135mm and its stunning for shallow DOF portraits but doesn't focus close enough for some product work, neither will my 50mm. Which is where the 24-105 works with a slight macro on it. I find shooting smaller objects at closer distance at F11 on around 40-55mm gives me a more natural to slightly dynamic look with more depth of field than zooming in and loosing DOF. For much of my really nice bottle shots its always the 135 though.

So would the 24-70 focus as close as the 24-105, and how much sharper will the mkII be? And is the OOF noticeably smoother?

Now the 24-70 range has always left me scratching my head. I use 35-55 settings the most along with 75-100 for portraits, plus 24-30 a fair bit for backgrounds for comps , architecture and landscape.

So i hear you say why not 24-70 for most then 85 for portraits - well i'm usually tripod'd and when shooting a succession of different heights and shapes business people in busy stressful environments I don't want to be moving the tripod to recompose the shot every person, from much experience its clumsy and looks like you are flaffing.
This where the 75-100 zoom range works so well ( most are shot at F8 for some focus drop off and best sharpness)
and I can get some slightly wider or even tighter if options are needed.

So why not the 70-200 for those then? well quite frankly I hate it, I know it is an amazing lens but its huge it puts non model sitters off, and is unbalanced and generally I woundn't use over 135.. and as I said the 135L is beautiful and so much more balanced.

In my opinion Canon needs to make a F2.8 24-105 or F2.8 28-110 both with slight macro that is tack sharp, little distortion & vignetting whilst having a smoother OOF / bokeh than the 24-105 or 24-70 more like the 50 1.2. And I would pay a lot for this :)

Are there any others in my school of thought / use out there? And what would you recommend ?

<p><strong>Vietnam, Laos & Cambodia

</strong>I’ve been busy the last few days travelling and sleeping. The 24 hour journey from Toronto to Hanoi was completed yesterday, and we spent most of the day shooting and eating in the old quarter of Hanoi.</p>
<p>The shooting condition in Hanoi have been less than ideal, a lot of fog and rain. We still ended up getting a few good shots on day one, and we’re hoping to do better on day two.</p>

<p>I’m going to be travelling Northern Vietnam between Hanoi, Cat Ba and Halong Bay. Then we’ll head to Luang Prabang in Laos and will spend time there, as well as Luang Namtha, Nam Ha and Vientiane. From there, we’ll be heading south to Siem Reap and visiting Angkor Wat. We have some other days we have filled yet, so I’m sure we’ll end up somewhere else that’s pretty cool.</p>
<p>I am going to have some help posting to Canon Rumors over the next 3 weeks, posts may not come the time of day you’re used to.</p>

Sigma 35mm F/1.4 Reviews - Vignetting Disparity?

Anyone else see a large disparity in the lens falloff measurements of the Sigma 35mm F/1.4 in the various reviews?

The Digital Picture lists a horrendous 3.5 stops on FF @ F/1.4 and 0.7 @ F/16 :(

Others such as DxO say the vignetting is normal @ around 2 stop wide open.

The copy I had and returned was in the latter camp having average vignetting wide open but nothing that made me notice it.
The front focus problems, yes, but not the vignetting.

Maybe there is a wide variance in samples and the 3.5 is the worst of them?

Is the 5D Mark iii a considerable enough upgrade from the 5D Mark ii?

I am new here and have my first question :)

Is the 5D Mark iii a considerable enough upgrade from the 5D Mark ii?

Considering purchasing a 5D Mark iii and currently I own the 5D Mark ii. So basically I have the money and plenty of great lenses so I would like to upgrade to the 5D Mark iii but I wondering if it is worth the money and is it worth upgrading. I have my opinoins but I would like to hear others on this topic. Going from a 5D Mark ii to a 5D Mark iii will I really be gaining that much? And lastly is it worth it?

Thank you everyone

Changing the focusing screen on my 5D III - two steps forward, one step back

Coming from a 5Dc with an EE-S focusing screen, I was pretty disappointed that the 5D III didn't have a similar alternative. Doing some searching, it appeared that focusingscreen.com is currently the only option around. In short, a guy in Taiwan gets original Canon screens and modifies them - there are various microprism/grid/etc screens, but since I like the freedom to manual focus anywhere in the frame, I went with the S Type.

It arrived yesterday, meticulously packaged, and I got to work using their online instructions:
http://www.focusingscreen.com/work/5d3en.htm

As I was finishing the installation, I accidentally dropped one of these screws inside the camera, and as luck would have it, it dropped into the hole on the side of the mirror, where I can't see or reach it.
006.jpg


I turned the camera upside down, tilted it, shook it a bit - I could hear the screw rattling around for the first minute, and then it just stopped - I guess it got lodged somewhere.

Thankfully, the part that's held down with the 2 screws seems to be solid enough with just 1, but I'm not really happy about literally having a loose screw inside the camera, just waiting for the right time to break free and go exploring inside a lens... Maybe I should register screwloosephoto.com and capitalize on my mistake.

As for the focusing screen - it works great, same as my previous EE-S screen. To me, it makes the difference between trusting myself with manual focus through the viewfinder, and using it for emergencies only. A bit pricy, but totally worth it in the long term. Despite whatever reason Canon gave for not having swappable screens in the mk III (something about how it's a side effect of their new AF), the various AF modes continue working fine.

If anybody has any ideas on either getting the loose screw out (I was thinking of trying canned air) or at least finding a replacement for it, I'd be eager to hear it.

Film shot on a 5D Mark III and Glidecam in Italy

Loving this combination!
I get asked often if I use a Jib with my shots. I'm a travel videographer that has to travel as light as possible in most situations. These 2 beasts keep on impressing me. Take a look at my most recent video? It was the first film I shot Flat, as well as the first where the Glidecam didn't leave the DSLR. Tell me what you think :) :)
