Lenses / Re: 70-200mm F 2.8 IS 2 VS 70-200mm F4 IS
« on: January 02, 2014, 02:27:23 AM »

But unfortunately, I was disappointed with the 2.8 IS II. I thought it would be a "halfway point" between the 70-200 f/4L IS and the 200 f/2L IS, but unfortunately the reality was the 200 f/2L IS at f/4 has more smoother backgrounds than the 70-200 f/2.8 does at f/2.8!


Bokeh is not really the strongest point of the 70-200 2.8 II. It can get real nervous under some conditions.

I believe there always are some compromises in the design of zoom lenses. Yes even in excellent lenses such as the 70-200 II.

I expected more resistance from the lens mount on a magnesium body which eventually supports lenses that weigh several pounds. :o In practical use, a 6D with Samyang 14mm would be more appropriate to stand behind the goal. 8)

Guess you never played football. The player in question gave it quite a whack.

Also, a 6D wouldn't make any sense ... you need the fps that the 1D bodies offer to shoot a fast game like football.

I would love amazon even more if it didn't collect sales tax.


+1...I would support local camera stores IF ONLY there is no sale tax. With my recent purchase, 400mm f2.8 IS II price tag + .0775% sale tax =   :'( :'( :'(


What happened to the 300 f/2.8 II?


Love everything about 300mm(from IQ, light weight, AF-speed) just little short for my shooting. Decided to go with my original plan, the 400mm. According to MTF chart, the 400mm is good as 300, with 1.4x TC is slightly better. I'm speaking on paper data of course.

Excellent! How do you intend to handle the weight (3.85 kg)?

Happy Shooting with the new lens!

EOS Bodies - For Stills / Re: 5DMkIII AF performance at f/8
« on: December 19, 2013, 03:27:07 AM »
I would suggest that you are better off sticking to the 7D with the 100-400 rather than shooting with the FF + 100-400 + 1.4TC.

I tried this combo and it worked reasonably in good light. That said, if you are looking for pixel level sharpness, forget it. Also, if you are shooting birds in the trees, you lose AF, hit a max aperture of f/8 and in dark foliage, are at ever increasing ISOs to render the images unusable.

Personally, I would prefer to use the extenders only with a f/2.8 or a f/4 lens.

EOS Bodies - For Stills / Re: The Unthinkable: Swapped out 5D3 for 6D
« on: December 19, 2013, 03:21:06 AM »
I've owned the 85L for a grand 3 days now and so far, I've found it to work pretty accurately on the 5D3. I'd guess the focusing would be even better on the 1DX.

Interesting - do you use af point expansion or single point af? Just looking at the specs, a 5d3/1dx center point shouldn't be better at af'ing than the 5d2/6d if the f2.8 line picks up, but on the other hand everybody states that f1.2 on 5d2/6d is horrible to use and that's why I've given up on the idea to buy such a fast lens... but mostly because focus & recompose from the center point is so tricky.

I use both AF point expansion as well as single point AF. I've taken a fair few shots of my daughters with the corner AF points with a pretty good hit rate. For the 5D3, the 85L falls in group-A where you have the additional 20 cross type AF points (f/4 vertical and f/5.6 horizontal) enabled (see blue focus points in below image).

The images which were out of focus were more because of my poor technique than the gear. I've found rocking back or forward ever so slightly when shooting with very limited DOF will render the shot OOF.

Same goes for situations where the subject is in motion. I had a hell of a time last night trying to shoot my 1 year old niece in very low light - she was seldom still and I got plenty of OOF shots shooting wide open - stopping down to f/2 and more increasing the DOF improved the images.

As far as I am concerned, the 85L focuses excellently with the outer points on the 5D3 unless it is user error and/or subject is in motion. "Sincere" doubts over its focusing ability without having tested the combo are obviously unfounded.

I've also heard (maybe someone can confirm if I am correct) that the 85L focuses faster on the 1DX. Supposedly, the 1DX supplies additional power to the lens motor which makes it faster.

How about a handheld shot indoors in a dark room at 300mm and f/5.6 (with the 70-300L), for .8 seconds at ISO 10,000?  Is that not low light?  If a 5D3 can autofocus in that amount of light, I'll go buy 10 of them tomorrow...

Those settings would result in close to EV +1. The AF working range of the 5D3 is between EV (-) 2 to (+) 18 so yeah ... it will autofocus.

Correct, because I wanted the image to look like the lights were on, even though they were off.  So I used positive exposure compensation.

I'm not sure I understand your post.

Lenses / Re: DXOMark: Sigma 24-105 f/4 DG OS Reviewed
« on: December 18, 2013, 11:08:40 AM »

I can easily imagine a salesman in photo store babbling something like:

"Yes, this is a new Sigma 24-105! It's a great and mighty lens, just released! But... Look at this display for a second -- this is original Canon 24-105! See this red ring here? It's L-lens! Feel how small and light it is! IQ is just is as good. Do you like it? It's usual price is 3 hundreds more than Sigma. But today only for you, I can sell it for the same price as this 3rd party Sigma! And I even will add a filter and this Lowepro case for free!!! Because I see you are real 'pro' who need a lens like that!"

 ;D

Sure if the salesman spotted a noob contemplating this lens. 

People with commonsense will be better off buying the Canon 24-105 used on CL

What is your point?

Only that even in other parts of the world, the Canon lens is available for substantially lower than the MRSP when it is purchased as part of a kit.  So even in other parts of the world, the Canon lens is available for much less cash, as part of a kit, or used as the case may be.

I live in India and the Canon 24-105 can be purchased for local currency that is about equivalent to $ 900 - A used lens can be had for as less as $ 650. So what I was implying was that the Canon lens is available in other countries as a cheaper price too. Sigma will be priced above the Canon lens (when it is released here) - I doubt too many will buy it over the Canon lens.

I guess it is pretty much the same all over. but then, maybe in your country it may be different.

PS: Photography gear in India attracts customs duty of 30%, so @ $ 900 the lens is a bargain.

PPS: English is not my native language and I sometimes have difficulty getting my point across.  :(

Regarding profiles, I found Adobe's free DNG Profile Editor to be a nicer program than the X-Rite one.

As for the question why do we need them? Well if we think about it, the out of the can ones do not make any allowance for the lenses used, they can't possibly be neutral for all lenses, the only way you can normalise your output is if you normalise your input.

Hi, how would the workflow look with this? I am using LR4 today, will upgrade to LR5 soon. Will I have to convert my RAW-files to DNG ang applying this filter before importing to LR?
Thanks!


All the information you need, is available here -

Yeah, it only undercuts the Canon because DxO still has the 24-105 costing 1250, which is far above its current street price.  It may be a slightly better than Canon's 24-105, but with the Canon version selling at 600-700, the Sigma isn't quite the bargain as when the Canon sold at 1250.

Canon's MSRP for the lens is $1149.

That is somewhat irrelevant since that is not what people are paying for it.  The question would be what is the actual street cost of the two lenses.
That is somewhat relevant since not the entire world is living in the countries where the street price is the mentioned above.

As a corollary, Sigma lenses aren't available in the entire world  ;)

Even in other countries, the Canon 24-150 as part of the kit will be available for roughly equal to or less than the Sigma.

BTW, from personal experience, Sigma's after sales support in other countries sucks big time!

EOS Bodies - For Stills / Re: The Unthinkable: Swapped out 5D3 for 6D
« on: December 18, 2013, 05:18:21 AM »
Consider this, you are shooting a subject at a distance of 5 feet with an 85mm lens at f/1.2.

To be fair, the f1.2 dof is a challenge for any existing Canon af system because even the 5d3/1dx af points aren't spread far enough so there is no need to recompose, and this thin dof beats any phase af precision... learning to manually focus on the lens or moving the camera is a good idea, at least with macro shots I know it beats trying to phase af.

I've owned the 85L for a grand 3 days now and so far, I've found it to work pretty accurately on the 5D3. I'd guess the focusing would be even better on the 1DX.

 It's a challenge on the 6D though and I'd like to use a tripod and live view for shooting with this lens.

I'll do some test shots with both bodies and post the results.
