Still no AFMA...something that doesn't cost them a dime at this point. In fact it probably costs them extra to disable it from the common firmware code base.

...the aperture is at f/5 and things developed too fast to take time to stop open it up to f/2.8 which would have produced a better background bokeh.

I rather like it the way it is...the bird's entire wingspan is reasonably in focus...2.8 would probably make it too shallow and you'd lose the wing detail...jmo of course.

I really like how simple snapshots look with this lens:

tested on the mk3 and it works fine aperture registers correctly and it has AF confirm

Thanks for the info! I emailed them a few months back and never heard from them, but I'll go ahead and order one based on your experience.

I grabbed a couple of these from this seller off ebay

They arrived yesterday and I installed them on my Lensbaby composer pro with sweet 35 optic
and on my samyang 8mm fisheye

really well made and come with a really nice accurate little plastic locating template so you get the chip in exactly the right spot as well as some little plastic filler/spacers to bring the height up (which i needed on both these lenses.
I glued them on with araldite a 2 part epoxy glue that sets quite fast but not too fast allowing me to get the position just right, importantly the glue does not have vapour like superglue which could mess up the rear lens element.

I followed these programming instructions and it all went perfectly

I hope this info helps anyone else looking to do the same

Do these work with 5D3? The chinese chips that include AFMA don't work with 5D3 for some reason...

I might also consider magic lantern and focus peaking once the software gets out of the early testing stage.

Um, my usual comment: On other than the 2012 cameras ml is stable and proven for years - though on 6d and the op's 5d3 you have indeed to wait for the official release.

I've used the current ML beta for 5D3 and it works pretty good for focus peaking. The downside is it's impossible to see it when shooting in daylight.

I've also used AF confirm chips for this. The only problem is if using an adapter, you need a chip that has programmable AFMA in it because the thickness of the adapter is greater than the AFMA span in the camera. Unfortunately I haven't found a AFMA programmable chip that works with 5D3. I've found some that work great with 5D2, 50D, etc., but not 5D3. The non-AFMA-programmable chips seem to work with 5D3 but that rules out using an adapter.

Hehehe...plus he looks like a mix between Anderson Cooper and Ellen Degeneres with that grey hair and jacket...difficult to take him seriously  ;D

LOL, note to self..."Never do an internet video. Ever."   :D

Entertainment value of video aside OP is just asking about what to buy next, which is fair enough.

I don't trust anyone who doesn't know how to say "ISO."

Maybe it is some sort of weird dialect?  ;D

Concerning OP's question and the conclusion the video makes, my experience (after owning 5D2, 6D, 5D3) is the 5D3 is noticably better than 5D2 in terms of noise and ISO performance as ISO increases. The difference in noise is as others have pointed out: less banding, less color noise, and a more "film like" noise pattern.

I can tell you different editors and NR softs will make for slightly different conclusions when comparing the two bodies. I use Capture One v7 here and when comparing in that, 5D3 is noticably better in terms of noise and ISO.

That said, 6D (which I had for a short while and sent back for a 5D3) was even a bit better at noise and high ISO than 5D3. If these were my primary concerns, I'd probably have stayed with 6D. But despite how good the 6D center AF point is in low light, the 5D3 AF system is in a different league altogether, as is build quality, and these swayed me to 5D3 and very happy with it.

And all of that said, I'd take the 6D over the 5D2.

On the other hand, I cannot imagine a situation where I set the aperture AFTER focusing, so I don't see a big issue here.

Unless you're shooting wide open or focusing manually with the DoF Preview button pressed, you're stopping down after focusing every time you shoot. AF is always performed with the lens wide open, regardless of the aperture selected. The lens stops down just before the shot, and that's when focus shift occurs.

Do you see a bigger issue now?   ;)

Ah, thanks for the edification.
Indeed, then it would be a VERY BIG ISSUE, and then I wonder why that hasn't been all over the internet already! Maybe sample variation did play a role here?  ???
BTW, not that I am personally interested in this lens, but would this be true even if one is back-button focusing?

Yes, true no matter how you autofocus.

Maybe they are dealing with it in the lens AF firmware? Basically an "on the fly AFMA based on aperture" of sorts perhaps? Would be interesting to compare the observed shift doing manual chart shot vs AF chart shot at various apertures.

Lenses / Re: UV filters (any difference?)
« on: March 03, 2013, 07:37:51 PM »
A cheap filter will negatively impact your sharpness, and add flare.  A good filter will not reduce sharpness, and will only very slightly increase flare.  I'd go with B+W MRC (or Nano) or a high end Hoya.  Skipping the filter is better than a cheap one (but your 17-40 needs one to complete the sealing).

^^^ +1 ^^^

A couple of years ago I had the same question, read the advice, tried the cheap ones anyway, now have only good ones after seeing everybody was right about getting good ones.

BTW, B&H has very good price for the 77mm B+W mrc (non-nano).

Lighting / Re: Which flash for a 5d mkIII
« on: March 03, 2013, 07:07:10 PM »
Another thought is doing a third party flash. I just got the Yongnuo YN-568 and it's great with the caveat that the AF assist beam will only illuminate the center 9 points (or so, depends on subject distance/focal length). But other than that, pretty nice unit for very little money. Then there is the Nissin 866 with a built in sub flash for fill in, a feature I think would be useful. I think both of these have high speed sync which you might want if using for outdoor fill. Price points are roughly 1/4 and 1/2 that of the 600 respectively.

On the flip side you tend to get what you pay for with Canon stuff, and it's really a matter of whether the "shortcuts" of the third party stuff will cause you problems worth spending for Canon. For these flashes it basically comes down to AF assist shortcomings and lack of the 600's radio. But the Yongnuo 622 ETTL radios can be had for about $80 a pair, so a cheap solution for that and then it only comes down to the differences in AF assist, which may or may not be a big deal for you.

LOL, I'm no flash expert and in fact a newb who just researched this very thing, so ^^^there's^^^ my core dump. Hope it helps.

Lighting / Re: Bounce flash with YN-568 question
« on: March 03, 2013, 03:37:58 PM »
Consider trying the ettl average mode?

I was messing with it and figured out switching to average mode fixes it, so nice to confirm it with your experience as well. Setting to average mode allows bounce to meter correctly.

Thanks everyone for your input!

BTW, I'm liking this flash at this price point, pretty solid value. I also have a pair of YN-460 II manual flashes and they are likewise nice bang for the buck.

I was skeptical about the AF assist but it actually works pretty good on the central points. I'll check later the actual number and placement of AF points it illuminates and post.

Some light reading


I saw that site. I've had excellent results using manual flash for bounce, so my question basically boils down to "do I have something not properly configured or does this flash have a problem?"
