Anyone tried sigma 50mm f1.4 lens on 5dm3... Any focusing issue ?

I'm looking between canon or sigma...

I have both Canon 50 1.4 and Sigma 50 1.4. But I always use Sigma as it produces rich colors and great contrast though the sharpness is slightly lower when compared to my copy of canon at 1.4. No regrets at all.Happy with the performance.

Sigma 50mm f/1.4 + Sigma 85mm f/1.4, cheaper option with no regret. It's a shame that Sigma didn't make a 35mm f/1.4!

Yes, there is 35 f/1.4 but not for FF body nia...sian!

the crop one is 30mm f/1.4 ;p

Yah sian no FF version

My weekend with a Canon 5D mk3 | Spencer Boerup Photography // BLOG

Great review of the 5D Mk III.

You should try the 50L then compare.

Just to share one more pic taken with 5D3.....

This picture is a bit dark, and the bokeh etc depend on the lens. This exact same thing could have been taken with a D90 nikon years ago. What would be useful is to see whether high ISO performance was better with a 5D3 body -- which means you'll need to share the whole big file (perhaps on imgur.com or something).

I took some time to do a simple test of the focusing accuracy of my Canon 5D Mark III as follows:

i) I took a regular shot using phase detection focusing (non-liveview).
ii) I then immediately switched to contrast detection (liveview) and bumped up magnification 10x.
iii) I depressed the shutter button half way. The focus did not change at all.

I was very happy with the results of the test. Focus was bang on and the photo looked sharp.

I then used DPP to boost sharpness from an in-camera default of "3" to the maximum "10". The following photos show results of the post processing. EXIF Data can be found following the photos.

Impressive! Assume you used tripod and no flash. Thanks for sharing.

Better put a specimen watermark on that shot of the $2 note.

Thanks for the advice... will do it right away!

Thanks... yes, tripod (with cable remote) and no flash.

Now feel like buying one too... lol... since 24-70 is taking forever...........

I bought mine two weeks ago... no regrets!

hey guys... like to check with everyone does anybody encounter the same issue as me...

my 5d3 hot shoe came off when i mount my 430ex and i send it for servicing... now i'm worry is it just me using too much force or anyone else encounter the same issue?

I never had this issue with hot shoes from all the canon bodies i've used. It should be able to take a reasonable amount of force though you shouldn't need to apply too much to slide the flash in/out. You ever had any problems with other hot shoes?

Did it happen while mounting or removing the flash? If the problem happened while removing, then the following could have been the cause. My guess.
I have been using 580 Ex II and never had such problem so far. I don't think it is the problem of the force applied. It could be the problem due to not disengaging the locking mechanism completely before pulling out the flash. When you connect the flash, you do not need to do anything with the lock lever in the flash and simply push in. It locks automatically. But, for removing the flash, you need to make sure that the lock mechanism is totally disengaged by sliding the lever on the flash before you pull out. Improper disengagement of the lock while pulling out will apply more force on the hot shoe that could end up in your damage situation. Canon should be able to rectify this. But, be careful with disengaging the locking mechanism in future.

I'm just curious, why does Canon always use a "special" sensor for the 5D that they dont use on other models? The 5D2 had the same story..now the 5D3…
No other models in the Canon line uses the same sensor (which can be a bad thing). Even the 1DX sensor is rumored to be in other models coming up and is already used in the 1DC. The old 18MP sensor are used in ALOT of models like 60D/7D etc…
I just wished the 5D3 used the same sensor as the 1DX since it kinda looks better than the 22mp sensor if you ask me.
Isn't it more cost effective also to "share" sensors than to create one specially for just 1 model? Even car makers are sharing parts and are making their cars better than dedicated parts.

So..do you think you will see the 5d3 sensor in future models? Somehow i have a feeling they won't and wil reuse the 1dx sensor instead for newer models…just like the 5d2..

There are some good points made. I guess unless we work with the design team at Canon, we will never know the true answer. Here are some thoughts I have:

i) The 5D3 sensor stands on its own... meaning that it produces great photos for those who know how to get the most out of their camera. Canon was careful not to produce a sensor that was materially and effectively inferior than its predecessors... namely the 5d Classic and the 5D2. The 5D3 sensor is every bit as good if not marginally better than its ancestors.

ii) The 1DX sensor maxes out at 18mp. I think that most of us would agree that if Canon introduced an 18mp sensor, the entire Canon community would be in an uproar. It would be intolerable to go backwards from a 21mp sensor in the 5D2 to an 18mp sensor in the 5D3. It was bad enough that the competition came out with a 36mp sensor.

iii) Many rumours are predicting that the upcoming entry level full frame will incorporate the same 5D3 sensor as part of its package. This may become the first time that a 5D sensor has been shared with another model.
