p.1 #1 · p.1 #1 · Low light focussing 24-70 f2.8 II+ 5d3


So I just picked up a new 24-70 f2.8 II today and to say I'm impressed with the focusing would be an understatement!

I just did a direct comparison between V1 and V2 (on a 5d3) and there was an object so dark I could hardly see it and after a *little* hunting the V2 lens got it but the V1 lens wouldn't lock on at all.

And it was *dark* - I'm talking 1/8th second, f2.8, ISO12800 for the scene, but the object was probably 2 stops darker than that and really lacking is contrast.

The sharpness difference between my V1 and the new V2 is startling.

Best money I've spent in ages! I'll be so confident with a 24-70 in church again. My V1 was... so so... when it got really dark

I'd be curious to know how big of a difference with an f/4 lens on the 5D3 under those conditions.

This is NOT good news (for my wallet)! I need to add a fast standard zoom, and have been debating the v1 vs v2 for a while...

I have to say, I had an assistant shoot for me recently who had the 24-70 mark II. He let me test it out for a few shots and I honestly wasn't impressed by the focus on my 5D3. I was shooting in low light and for some reason it seemed slower than my 24-70 mark I. Image quality also didn't blow me away, or the feel of the zoom ring. The lens should be $1600 and in my very short time with it....be a bit more of an upgrade.

Exactly the opposite of my experience in every respect. Maybe there's an issue with that lens? There's no reason that the V1 should outperform the V2.

Here's a quick test I did last night. It told a few things:
* Firstly, the 24-70 V2 was perfect focusing out of the box. I'll MA it, but I don't think it needs it - at least at 70mm.
* Secondly, the 24-70 V1 wasn't perfect focussing even after careful MA with FoCal a month ago - two shots in sequence gave the same result.
* Thirdly, the 24-70 V2 is pin sharp, even at f2.8, whereas the V1 lens clearly isn't, although I think the lack of sharpness on the V1 shot is a combination of focus and lack of sharpness.

It's a poor test really, but a "real" one. In the end, I use my kit in a real way (although I can't remember the last time I shot at 1/30th handheld!).

I'm pushed for time but I'll try to do some proper tests after christmas. However, it makes me much MUCH more confident to use the new lens in dark conditions, due to increased sharpness and increased focus accuracy.

For now, I'm delighted...

From my few tests, I'd say it equals my 135L and 35L for focus accuracy, but I'll know more tomorrow when I MA it

Phil, my experience is matching yours. This lens is as good as 70-200 f2.8 II
This is a lens I'm using ~70% during events shooting.
Very quickly this lens has become my most dependable lens.

This year my 2 best acquisitions were: 5D III & 24-70 II. This combination was made in haven

So I found a little time to do a few tests.

My copy has pretty much the same sharpness from f2.8 through to f7.1, with a slight peak at f5! That sharpness is 90% of the sharpness from the amazing 135f2!! It also had a focus consistency of 98+%, which is the highest I've ever seen from any lens. It was also sharper than then 35L. (all tests done in FoCal - centre sharpness only)

It's just incredible. I can't believe this zoom is outperforming some of my best primes!

Anyone who doesn't think this is a worthy upgrade hasn't tried it or has a bad copy because I can't believe how good my copy is. Its better than I expected. And I've done sensible and realistic tests.

My expeience is similar to Phil's. The 24-70/2.8L II on a 1DX is incredible!

Canon should feel rightly very proud. To make a lens which has a flat sharpness curve from max aperture to f7.1 is nothing short of incredible IMO.

Maybe there was a problem with that lens but it was band new (but a rental). I was using the lens in servo mode and it was surprisingly slow.

I'll have a better chance to test it out in real conditions over the next few days, but so far I'm impressed..

I am joining the chorus here.... . I have been using the Mark II for two months now and I am extremely pleased with its performance on my 5D Mark III. For sure it matches the performance of the 70-200mm Mark II, making that combo f/2.8 zooms hard to beat. As an additional note, I would to add that all my Canon lenses in the last 2 years or so was great straight out of the box without any need to do any MFA.

My shooting style with both and most lenses now on the 5D Mark III is to leave the AF mode on AI even for (semi) stationary object. For portraits where the model/target moves for example, I just have to make sure the AF point covers the closest eye and so far, the keeper rate as far as in focus images concerned has been extremely high.

I did MA the 5d3+24-70II and it turned out it needed -2 and +1 (wide and tele)... or hardly noticeable. I would say that the 5d3 needed a lot less MAing than the 5d2 for whatever reason.

Yes AI servo is now very accurate, especially if you have it set to "focus priority" on 1st capture. I still personally switch, but I do understand why you wouldn't. I just like to see the flash to know I've got it (although that doesn't work in good light :S )
