EOS Bodies - For Stills / Re: 5DIII AF Point Issue
« on: December 20, 2014, 01:40:21 PM »
Hmm, that's concerning news. Could it also be 1dx issue?

*edit* I just tried aiming at something I could easily see a shift and activated the show AF point and it's a little above where I aimed.. Can this explain why I always hit the eyebrow no matter how much I use the spot AF center in the eyes..?

I had some initial difficulties with 50A, but after service and calibration with the USB dock it has worked fine. Granted, the weather has not been photographic for two months here, but still.

The 50A is far more reliable than EF 50/1.4 with the center focus point, and I trust my 5D outer focus points only on bright and sunny days anyways and when my object is not too close with about any objective I have.

What I recall is that the non-central focus points did not work well with 50A, but they don't either with EF50/1.4.

It does make me wonder whether varying lighting conditions can throw the 50A focus calibration off. I do recall seeing that the results were slightly different when adjusted under room lighting and under sun light. The other thing I can think of could be repeated thermal expansion and contraction.

For testing I only use the center point. And, again, mine worked for 6 months before it shows the same issues the THREE other Art lenses had.

Different temp light has something to do with it now, but didn't before, and it's actually just as good in the dark as it is with bright sunlight, it's slower in the dark, of course, but it was as accurate. And for at least 5 months it just didn't miss at 1.4 (the only aperture I use with it.) now the AF seems to just guess wildly and you cannot get two shots in a row or even 2 out of 10 that are anywhere near equally sharp, and once a week a shot is tack sharp.

The BIG concern for me is if they fix it so it actually works again, how long before it fails again? I'm SO hoping for Canon to make the same exact lens but with the newest USM motor and algorithm's. I will take the 35 L II as an option  ::)

Infrared: I fully understand how to calibrate. I have had FOUR art lenses and they all have the same issue, my second 50 art has been fantastic since April or May when I bought it. It was easy to calibrate and I just yesterday went through some picture from this summer when it was bolted to my camera and it is epic sharp and worked perfect.

It has now started with the same issue as the others. Dial in whatever afma values you want it doesn't matter. So it is something wrong with it.

viggo do you have access to a 5D3 you can test it on?

mine is still amazing easily the most consistant and accurate AF 50mm i've ever used
its blazingly good in servo too (but i only use the 5 center column points using servo)

I have only the 1dx, but even with only center point with or without expansion points in any Servo or One shot mode it's the same results. I'm seriously considering a 35 L or 50 L AGAIN... At least the 50 L is pretty consistent and can be calibrated without wearing out the shutter with testing.
cant try it on another body in the shop?

its wierd mine was so far off out of the box but after calibration its been fine, sure it misses now and then but definitely not anything as bad as the canon 50 f1.4. I wonder if your new body firmware messed it up? can you try roll back the 1Dx firmware to the old version when it was working ok to trouble shoot it?

I can absolutely guarantee it's not the body. The 2.0.3 firmware, as I wrote earlier, was a long time before the Sigma, so with the 50 art both the firmware of the lens and body has been the same. And it has worked great, but started to drift now. I did a test where I resat the lens to 0 and took some shots at +15 and -15 and a few values in between and it makes NO difference to sharpness of my shots. They miss and hit the same shots and are equally sharp.

Lenses / Re: FF Tamron 15-30 f/2.8 IS lens pricing announced
« on: December 19, 2014, 01:57:44 PM »
I can certainly see the appeal of it, but as you mentioned already, from an Events PoV... Also, UWA videography has possibly just gotten a fricktonne more exciting for lots of folk!

But this lens is DOA for most landscape work -- no front filters plus an integral hood were terrible decisions.  Though, in fairness, those decisions may have been compulsory to get 15mm.  It seems 16-35s have the flatter front element figured out (and thus are loved by landscape folks), but 14- and 15- FF lenses have to be bulbous to work effectively.

I'm not aware of any 14- or 15- FF lenses that take front filters -- are there any?

- A

Yup, the Zeiss 15mm accepts 95mm filter.

BTW, I am considering getting the 7D2, and would like to be able to efficiently do microfocus adjustment for my lenses. Could you recommend a good product? Is the Reikan FoCal straightforward? Or is it a bunch of fancy programming that is more trouble than just manually AFMA-ing a few lenses on one camera?

 Lenses used are the EF 400 f/5.6L (+/- 1.4 x TC),  EF 70-200 f/4 IS, and EF 180 f/3.5 macro (+/- 1.4x TC; don't laugh, I use this combo for 1:2 to 1:5 magnification shots of snakes, including venomous snakes). Also I imagine that I would work up the 35 Art, which sometimes serves as the "longish normal" lens on my current 60D when it isn't being the "wide-ish normal" on my 6D, and the EF-S 15-85, which is the casual walk-about lens.

Unfortunately I can't use MF for my photography.

Reikan Focal is very very easy to use. The "tricky" part is setting up properly.

Use enough light, preferably a non-flickering light like the sun. Have absolutely even light and NO shine or reflection.

Buy the hard target from Reikan.

Have your camera bolted down as sturdy as humanly possible.

Use the right distance.

It takes a bit of effort, but then you will get a value that works straight away. Just not the Sigma's. They run through the test without issues at all, it all looks great, start ahooting and you will spend thousands of shots trying to figure out the value while the lens misses back and front at complete random.

Two letters will describe where the 100-400 II leave the competition behind, I guarantee it; A F. And for a tele zoom like this I would say that is what matters most. Well, for me anyway.

I just love the 24-70 mk2, it and a 200mm goes nicely alongside a 50mm. Just don't buy the 50 Art lol ::)

Similar thread:

http://www.canonrumors.com/forum/index.php?topic=8583.0

It appears that if there was a firmware update, there'd be an abvisory note and you'd have to take it to a Canon service centre.

That thread precedes the user-downloadable update for the 40/2.8 STM pancake lens.  A camera released 2012 or later (including the most recent Rebel) can apply the update to the attached lens.  Even after that, there was a firmware update for some supertele lenses that required them to be sent in to a service center (but similarly, I can update the firmware on my 1D X myself, but a 1D C must be sent in).  I expect that if a firmware update for the 24-70 II is issued, users will be able to download and apply it themselves.

Thanks! :)

Thanks for sharing :) it would be interesting to see if everybody has the 1.0.2 in the 2470.

Nice timing for this thread!

Viggo, sorry to hear you are going through the aggravation, as you were enjoying the lens and had high hopes for it.

I just this morning reached out to a local lens renter to ask about his copy of the ef 50mm 1.2, as I'm seeing the value of in-focus dreamy over OOF sharp.  I'll rent first and see if I can handle the focus shift for closer subjects, which is a big part of my style.

I have sharp and fast:  Sigma 35mm Art, fantastic.  Canon 85mm 1.2, ultimate.  (Note that I actually sold an ef 35mm 1.4 after owning it for four months because it was not sharp and had the worst CA I've seen since my old Sureshot A-80.  'Course having come from Amazon, it might have gotten banged around, repacked, etc.)

As y'all might remember, I was another who got a 50mm Art with dodgy AF and sent it back thinking by now we'd have a firmware update or SOME response from Sigma other than, "Well, it is a particularly complex lens, and you really should buy the dock."  (That from their tech support.)

So, worn down from waiting for Canon or Sigma to put out something perfect...

Thanks! Yeah, I have enjoyed it so far, but ...

I sold the 50 L exactly because closer than 1-1.5m it's veeeeeery soft, to the point that if I used off center points I couldn't tell the difference between where it hit and the blurry parts, lol.

Called a service shop today and he asked the usual stuff, if it was constantly back or front focused. But when I explained that I use both the docking and Reikan Focal, he just said "ah, then we have some parts to change" so CLEARLY they are aware of the issue, and I already knew, but perhaps they have parts now that can make this go away finally. I REALLY like the lens for everything else, so fix the AF and it's completely epic.

There will be instructions on the download site.  Probably a similar process to that of the firmware upgrade for the 40mm f/2.8.

Thanks! So I guess the 1.0.2 is the only version as of now, since I haven't seen any update.

Lenses / Canon lens firmware update.
« on: December 16, 2014, 06:04:09 PM »
Hi guys!

I just noticed checking the firmware of my 1dx with the 2470 mk2 attached that it not only displays the camera firmware, but also the lens.

My version says 1.0.2 with the 2470, anyone else have something different, and how would I update it if there was a newer version available?

Thanks :)
