EOS Bodies - For Video / Re: Canon 5D Mark III - Resolution Review
« on: April 04, 2012, 09:48:18 PM »
I'm hoping that someone more knowledgeable than myself can help us interpret this.

Here is capture from the same source video as in the resolution chart tests that I did (video linked above in this thread). In this capture, the video is on the bottom and the still (scaled to 1920x1080p) is on the top. I applied an EXTREME amount of sharpening to the video (more than anyone in their right mind would even dream of applying to real shots) and some to the still.

Under the theory (as I understand it) that sharpening cannot create resolution, I wonder what is going on in this chart? There are distinguishable groups of lines near the "10" (1000 lines) mark.

Does this mean that the 5D3 might have more true resolution than we think?

I don't think the actual resolution makes or breaks this camera. Though I want to get more real-world footage, I'm happy with what I'm seeing so far. I'm downright amazed at how much sharpening I can apply to real shots and it still look very nice. I'm just curious about this and had already shot the charts (a bit of a painstaking process - and it probably still wasn't done perfectly).

I'm just hoping someone can improve my understanding of how to read and interpret what we see in these charts.

Thanks!

Has the guy who removed the OLPF posted the absolute most dead obvious first step of a resolution chart shot with modded and unmodded bodies with downloadable direct from camera files and enough information to 100% reproduce the results? If not, he's hiding something, and I think his inducing people to damage their $3500 cameras is seriously outrageous if he is.

I agree with the idea that a resolution chart (comparison) would be useful here. As much as I like resolution charts, it is picture quality in the real world that matters most. A resolution chart would tell us if resolution is really improved, but it wouldn't necessarily answer how much aliasing shows up on certain objects (though it should show some aliasing, if it exists).

I don't think James Miller is really trying to pull one over on people, nor is he necessarily encouraging anyone to damage their own cameras. Anyone who does so based only on his two videos might deserve a $3500 paper weight.

What he has indicated will be forthcoming this week is a side-by-side comparison with an unmodded 5D3 and his modded 5D3.

I'm with peederj on this on. This is simply illogical. If the optical low pass filter is, indeed, optical, then it is in hardware. In live view, zoom in as peederj suggests. The resolution is there on the sensor AFTER the optics of the camera. So, any softening would logically come from the downconversion AFTER the sensor and the optics.

Having said that, if you provide an even sharper (dare I say even aliased) image to the same downscaling algorithm, it seems plausible to me that the result might appear sharper. But, that won't necessarily make a better image overall.

I won't be running out to mod my 5D3 any time soon, assuming this is even serious.

I've made a resolution and sharpness test of the 5D3 using a resolution test chart. I'm no pro, so I don't make more of this than it is. Still, I thought it performed quite well. My Canon 600D shows about 700 lines of resultion and this appears to show 800 or more lines. My Sony PMW-EX1 shows the full 1000 lines on the same test, which makes me think I've got it set up close to correctly - but I'm open to pointers and insights.

The video should be live on Vimeo in a few minutes.

Looks like another batch of bodies are shipping out today from B&H. I ordered 3/2 and was not in the first shipment last week, but my order status just changed to "Shipped." It will be a nice weekend!  :)

I don't want to rain on anyone's parade. But, I contacted them last week (Friday, I believe). They told me then that my order (565xx) would ship in their next order to be received the following week (which would be this week). So, I think at least one of us didn't receive very reliable information.

Okay, now I'll provide some sunshine.

My order status now shows "In stock, order sent to warehouse."   And my credit card has been charged. This is a change on both fronts from earlier today (not that I've been checking hourly or anything) ;D

Edit: I just checked and status is "Shipped." :)

I'm order 565xx.

It looks like I might have just made the cut. The good news is that this seems to confirm that the information I was given last week by B&H was accurate. Thus, I would tend to believe that the systems the customer service folks are looking at are fairly accurate.

Also, xthebillx, thanks for starting this thread. And, please check your messages. I PM'd you regarding editing your post above.

I've been a loyal B&H customer for a long time and I defended them leading up to last Thursday. I still defend them, but that doesn't change the fact that I'm disappointed. They haven't been unfair or unprofessional. Rather, I'm disappointed that my loyalty didn't pay off because B&H didn't get as large an allocation of 5D3 bodies (relative to their pre-orders) as others -- meaning, I would have been better off ordering from someone else in this case. I'm also disappointed in Canon, as they have neglected their existing customer base by providing more kits than bodies to retailers (such as B&H), again relative to pre-orders.

I think 3/22 was the first shipment.

hate to say it, but there is so much bad info in that video there, so much very wrong, very wrong

Care to elaborate?

I'm growing a little weary of EOSHD's soapbox. I get it. The 5D3 isn't what he hoped it would be in terms of resolution.

JCS has shown here that it appears best to set sharpness off in order to get the best out of this camera. Why would someone doing comparison tests set sharpness up rather than down? Why not set it the way JCS has and then sharpen in post? Why not put 5D3, 5D2, and GH2 through actual resolution tests with resolution charts? Why continue to use ALL I-frame if IPB doesn't have the problems?

I'd love to answer these questions myself, at least as far as the 5D3 is concerned, but I'm still waiting on mine. :( Perhaps this weekend... In the meantime, I'm learning from others' and appreciate the reasonable approach that I've seen from JCS, as opposed to the approach some have taken who seem more emotional and less interested to get the best possible out of the 5D3.

Are these kits or body only that you are now getting from Crutchfield? And, when did you order them?

It looks like Canon is to blame for not supplying enough Body only units compared with kits. Kits appear to be available nearly everywhere, even direct from Canon. Still, those of us who ordered body only are left without it.

This is disappointing, as those most likely to order the body only are loyal Canon customers who already have good lenses.

Perhaps I can set a model for the answers that you (and I) hope to get on this thread.

My order was number 565xx and I ordered at 7:40 CST on 3/2.

I was not in the first shipment. I contacted B&H 3/22 afternoon and they said I would be included in their shipment next week. I'm not taking that to the bank, but at least I'm hopeful. I'm disappointed that I wasn't in their first shipment, but it is understandable due to the high demand. Have Best Buy or Amazon filled their orders in quantity?

We also have the OP/TECH mentioned above. It fits well what you asked for.

You might also consider the Sun Sniper Pro. It attaches to the tripod mount, not the sides. Thus, there's nothing to scratch the body except your clothes.

Just talked to them. Body only is now out of stock.
