OFFICIAL: CANON EOS 5D Mark III - User Thread - Part 2

[avsquare]

first off, I'm merely a hobbyist like most of us in this forum.

Custom functions I'm referring to C.FNs such as:
- change front and rear dials to control aperture/ shutter speed in manual mode
- set mirror lock-up

I was trying to "configure" the 5D3 showroom unit to match my 1D3 but I can't find the menu page for the custom functions. The 5D2 and 7D that were on display has a dedicated custom functions menu. Maybe I overlooked this on the 5D3.

1Ds3 technology might be old, but it is still a very capable body. I rarely shoot at high ISO (even if so I have my 50L to take care of low light) and I don't need movie/ live view... I just want a solid and reliable body so that I can utilize my 16-35L better Used copies of 1Ds3 are going for 3k+ USD on eBay... as compare to 6k for the 1DX. For S$4k my preference would be a 1Ds3 instead of 5D3/1DX.

I see. Ok for focus related settings, 5D3 (and I suppose 1DX too) have a dedicated AF setting tab for that, together with AI Servo settings. For selection of rear-front dials to control manual exposure settings, it's still under the C.Fn menus, just try to look around again. The number of C.Fn has increased from 5D2.. it's not surprising that you can't find it. When I first got hold of the cam, I spent quite some time figuring out all the stuff and referring to manual too

And what's the condition of the 1Ds3 selling at eBay? I saw someone selling a used copy of 1Ds at $6k.

Can I ask 5D3 users here if your shooting style has changed due to more capable ISO performance like do u still shoot in low ISO if possible or allow it to goes higher like u don't care?

I really like the auto-ISO in M mode. Now can just tweak shutter speed and aperture settings much faster and let the ISO adjust itself.

agreed. It's like Av + Tv mode combined

set the shutter speed and aperture you want, let the auto-ISO handle it. It's more than enough for most situation and also because the cam has very usable high ISOs.

yup, this is how i shoot nowadays using the 5d3

Another big change for me is that I no longer have to use centre AF to lock focus then recompose. I can now choose and use the preferred AF point or area to focus straightaway.

I agree..this is especially useful for landscape shots on a tripod…however for handheld shooting i still think the old fashioned focus then compose method is faster

My new standard for blur-free shot is starting from 1/100 instead of 1/60.�
Do we still need IS ?
Actually, we can save some $ buying non-IS version.

Same here. Now, I "pre-framing" instead. Just aim my 9 points at my subject face and shoot.
In a way, it speed up my shooting as well as more accurate focus.

Just becos high ISO shots are useable doesn't mean we should always shoot at high ISO if it can be avoided? IS will allow you to shoot at lower shutter speed thereby at lower ISO to achieve similar level of sharpness. So yes I will still prefer IS.

IS is also useful to stabilize VF for telephoto lenses, and useful for video.

My subject always move ... Plus I seldom do video. So, IS is a plus point, not a must for me.
Say 200mm, if we double the shutter speed, IS becomes less important right.

Eh, I thought for landscape shots AF is the least critical.

If you have not been sleeping for a few days or had very little sleep the night before, IS is very, very useful at high shutter speeds.

in agreement. IS is useful for video and also, it is useful in situations whereby you want to capture ambient light by dragging shutter speed to things like 1/15.

and like bro esoeij, having good high ISO capability doesn't mean we need to "abuse it". If we can use a lower ISO with lower shutter but achieving sharp pictures with IS, why not? Lower ISO means lower noise and more details anyways and also, retaining higher dynamic range. I would try to aim for the lowest possible ISO even on Auto ISO mode.. if I see very high ISO generated that is abit overkill for the scene, I may tweak the shutter speed or aperture so that a more suitable ISO can be used.

I don't think it is an EITHER OR situation, but rather we now have more options. Why can't we use high ISO and IS for shots that was previously not possible?

One thing, I have set it so that my shutter speed does not go lower than X in settings (depending on lens mounted) because I prefer high ISO over slow shutter with the 5D3. Noise I can deal with, shakey hands etc alot harder to fix.

My setting is 1/125 �� but image still so clean !!!
Once, I saw an image with iso 10000, can't believe my eye. It is cleaner and still sharper and richer than 5dmk2 3200.

IS and high ISO should give you better results than high ISO alone. Of course you can use both if the situation arises. My point is not about either or, but that IS is still useful.

What focal length were you shooting at? If you shoot at say 200mm, you have to pump up ISO even higher to get a higher shutter speed, unless you have IS or a monopod/tripod.

The cheap and very good ef 24-105 f4 kit lens!
Now, F4 no longer consider "slow" match with 5dmk3. I think 200mm need at least 1/250.

Haizzz, means you were using IS right? Heh. Yah F4 is now useable indoors. But 2.8 or less still needed if you want to isolate subjects to get background blur.

Any idea if 5dmkii and mkiii video formats are the same?
Due to the Intra and inter codecs.
Was anticipating problems if i mixed the videos and they would be recognized as different file types and rendering would be a pain in the ass.

Thanks in advanced.
