EOS Bodies / Re: T3i macro video at 3x digi-crop?
« on: May 01, 2011, 08:12:50 PM »
the 3x crop mode is decidedly soft compared to the standard video; it has less artifacts (no line-skipping-induced aliasing/moire), but if you see tests of 3x crop vs zooming with the lens, the 3x crop is comparatively soft:
http://vimeo.com/20964077

that's because, even if it is 2.7x instead of 3x, as pgabor says, it's too much: you need at least a 2.5K bayer pattern to create a sharp 2K image

still, if you need it, it's really useful; but it has limitations

Isn't the digi-crop (not the 'zoom' that goes beyond 2.7x or 3x or whatever the true number is) the same as cropping a still the same amount in post?

The first video example is thru a 100 L and it is in a different league than the second due to the lens, just like a 3x crop of a still shot thru a 100 L or some other hi-resolving lens is in a different league than any "short to short-tele" zoom.

Now I would agree that 3x on APS-C  has it's limitations for the reasons stated, but using a stellar lens will make all the difference and it becomes quite useable as seen in the first video. And that is the same as I see when cropping a 100 L 3x vs cropping a 24-104 L at 100mm the same way (which is a better zoom than used in the second video).

So I'd have to agree that I'd love to see it on a 5d3 because that body hopefully will have enough more pixels to make the 3x fantastic when cropped in similar proportion. It would greatly expand the toolbox on the video side.

The focus shift is an annoyance. Raw performance doesn't matter if systematic errors spoil the game. That puts both the 50/1,2L and the Sigma 50/1,4 rather low on my list.

The newer "smooth finish" Sigma 50 is apparently much better in this regard. I have not tried the old one but took a chance on the new one when I saw good reports on it...tested it and found it has very little shift at all. My 50 tested to look virtually identical to the focus charts for the Sigma 85 at photozone.de.

Perfect! Thanks for the link, I gotta  say I'm impressed with the 3x. From what I understand there is no loss in video resolution at 3x and from the looks of the video sample it appears the 3x may be very useful.

EOS Bodies / T3i macro video at 3x digi-crop?
« on: April 29, 2011, 04:48:11 PM »
Has anyone shot any "macro" videos with the T3i 3x digital crop with a 100mm (or so) macro lens? I'd be interested in seeing clips if anyone has done it, plus of course hearing your opinions.

I'll see if I can post some shots over the weekend. The biggest two things I noticed are the color renditions and sharpening/NR.

Colors are absolutely amazing. I'll post a pic of one of my guitars that has 24K gold plated hardware that I never could get to look right until Capture One. Also, skin and hair tones same thing.

Second is the sharpening and NR. DPP will "out sharpen/NR" it at first glance, but when looking at details in the bokeh, DPP is not doing well at all in comparison. Meanwhile Capture One nails it and the bokeh still looks great when sharpen/NR and DPP never gets there even with as similar as possible settings. Also, DPP loses more detail at similar NR levels. I'll post crops of the afforementioned guitar that show it.

I would also encourage you to download their 30 day demo and try for yourself! They have two versions (pro, light) and either can be installed using the single download. Plus the demo can be activated without uninstalling/reinstalling.

I have $ allocated if they release a 24-70 II IS!

#1 is the 'body adjustment' and #2 is the 'lens adjustment', but your suggestion would require the ability to set the C.Fn to 1+2, and you can only make one selection.

I could have sworn I did it on my 50d...I'll double check it tonight.

Lenses / Re: L-fever...
« on: April 27, 2011, 12:56:31 PM »
Regarding 100 macro vs 100 L macro, I've seen a number of reports that autofocus of the non-L when using as a short tele is not very good. That plus the IS made the L worth the extra bucks for me. It does stink however that 3rd party macro flashes apparently don't readily fit the L...still investigating options for that...

That does seem high but on the otherhand if it works why sweat it? Obviously Canon felt the range needed to be +-20 to cover "reasonably expected cases" and that is why they made the range the way they did. But I can understand wanting it to take less and sending it in to get it closer.

Anyway, very good news and glad you have a camera that can do this adjustment!

Also, consider the fact that you can adjust both the "body" and "individual lens". So in your case maybe do the "body" +7 then your kit lens would be -7 the other two would be +9 and +7.

I posted this in the software section but will also follow up here since I started this thread.

I bought the PhaseONE Capture One Pro 6 RAW processor software and tried it out tonight. It renders in a totally different league than in-cam or DPP. The difference is literally bigger than getting a new L over a kit lens to my eyes, no kidding.

I'm giving the PhaseONE Capture One Pro 6 product a whirl. Just bought a copy after seeing some very good reports on it, will post findings in a couple of weeks...

http://www.phaseone.com/en/Software/Capture-One-Pro-6/About/Pro-Overview.aspx

I went ahead and d/l'd the demo while I'm waiting for my boxed copy since it can be activated without reinstallation.

WOW.

The difference between what I get out of Capture One Pro 6.1.1 and DPP is more than a new L over a kit lens.

No kidding.

Color, sharpening, NR is all in a completely different league. I had no idea 50d files could render like this.

I've calibrated 14 lenses on my 7D

–1   EF 100mm f/2.8L Macro IS USM

On my 5DII, I've calibrated 8 lenses and all of them have needed some adjustment:

+5   EF 100mm f/2.8L Macro IS USM


LOL, pretty much a smoking gun in my book for body tolerances...seems like if any lens would have tight tolerances for "right" (whatever that is), this would be the one.

I would agree that maybe micro adjust "all lens" or "body" (can't recall what the menu says). It looks like a bad front focus and probably the 10% good shots are when it "misses"?

Is that a proper "fix" though?  Manual says to avoid MF adjustments unless absolutely necessary.  Seems odd that a new body would be incompatible with so many lenses... no?

I found it extremely easy to do with a makeshift similar to a Lens Align Pro (basically a ruler and a small target). Helped a bunch and is totally non-invasive in that its just a setting on a menu that you can undo at any time. I'd sure try it out since it's free and only takes a few minutes...might save you sending all your stuff in to Canon, though I'm sure they'd fix you up. My new 50d seems to be off 5 or 6 clicks since my new 100mm L macro on this body needed +6 and a new Sigma needed +5...so I'm thinking its the body not the lenses...but very simple to fix no matter what is to blame (and who knows what it will be for the next lens?).
