Some News (or Rumor) About R10

And I don't think the lack of AA has that much big effect on the file quality.

Quality encompasses many different things, so any general way of relating the presence or lack of an antialiasing filter with quality would most likely be overstating the actual effect. Still, the influence of the antialiasing filter on sharpness and resolution is huge.

 

There is a rumour to the effect that Canon wants to get rid of the antialiasing filter eventually, and I tend to believe it. The strongest argument in favour of an antialiasing filter is that it simplifies the internal image processing. Eliminating moiré algorithmically is a hard problem, and the existing solutions require more powerful CPUs than those typically found in cameras. That’s why the cameras lacking an antialiasing filter are generally those geared towards a raw workflow, which is true of MF cameras, but also of the DMR and the M8. Once someone, be it Canon or another vendor, should manage to implement an effective and efficient moiré-removal algorithm in-camera, we will see less and less sensors with antialiasing filters.

What a truly bizarre and mathematical way to compare. It is quite easy to compare cameras. You take a picture with each, and compare them. If you like one better, buy that camera. Hypothetical relationship between pixel densities and crop factors are uninteresting, because in the end we compare images, not tech.

I absolutely agree with you on that, Michael. And I was not denying the pixel casualty due to the use of an AA filter. However, I really doubt that how much contribution it would be in terms of gain in sharpness and resolution due to the lack of one.

 

Color Foto has a test for the DMR with the 100 APO Macro, in their case, the DMR resolves 1313 lp/ph at ISO 100, they've also done a test for the 5D with a 50/2.5 Macro, and the result is 1358 lp/bh, which is apparently higher WITH an AA filter.

 

I've seen several other tests, the results are pretty much in line.

 

FotoMagzin you've written for probably has done similar tests too but I can't recall it.

 

These test results don't make sense at all if you believe that the lack of AA "should" improve the sharpness/resolution under similar test conditions. So I was suggesting that the only valid test would be to use the same camera, same lens, but with a removable AA, then we can get the ultimate answer, and of course, the conclusion could be way different due to different strength of the AA too.

[sdai]

A long time ago I saw a comparison article about a Nikon camera with AA filter and with AA filter removed. The visul difference regarding sharpness/clarity was significant, stronger than 20% pixels more or less.

 

That was impossible, if you could show me the actual proof. I offer to disappear from this forum indefinitely. If Nikon could do that, who don't they save some cost on AA and command much higher price for better picture quality? LOL

 

Nikon couldn't even build a sensor of their own.

 

I certainly hope your post doesn't reflect any part of German culture.

this isn't a forum for tossers

 

Oh yes it is.

Given its higher megapixel figure, the 5D should have resolved 1481 lp/bh then, assuming for the moment that resolution did depend on the number of pixels alone. Anyway, when JPEGs are compared, the 5D should win. That’s what I said: as of now, cameras without an antialiasing filter can only excel when used in raw mode. But the state of the art is evolving and it may not stay this way.

 

So I was suggesting that the only valid test would be to use the same camera, same lens, but with a removable AA, then we can get the ultimate answer, and of course, the conclusion could be way different due to different strength of the AA too.

Those comparisons have been made (see Hot Rod Visible, although one might argue they aren’t necessarily impartial). One might also compare images taken with the Mamiya ZD with and without its removable antialiasing filter, but then the ZD didn’t impress me even without the filter.

Actually, is there an optional AA solution from Hasselblad? they probably couldn't care less ... but if so, then you could conduct a direct comparison with the 39 or maybe 50 MP backs. It would be very interesting to see one possible ultimate answer to the question.

 

If you look at the EXIF in the hot rod shots closely enough, you can find the test is invalid, and metering, WB settings are wrong due to the possible IR mess up because the 5D used a sandwich filter with AA, IR cut and cover glass cemented together. The material Canon used is crystal instead of glass, that makes it absolutely impossible for the modifier to find a proper substitute after they remove the original one.

To clear it up, my posts was only regarding EH21's comment below, in which he says:

 

 

 

And I don't think the lack of AA has that much big effect on the file quality. That's it. No one is comparing the DMR to the 5D.

 

If you always feel the urge to jump the gun and take on topics you don't even bother to read from the beginning, carry on.

 

What is up with you? You posted after my post with no context whatsoever, so I naturally assumed you were answering me. I did read the whole thread, I have no idea what major brain malfunction causes you to think that I didn't. Btw, please stop with the prejudiced comments about Germans. They are not funny, and they are not correct.

You know we have been urged to adopt an average European mix of cultures with some North American influences. Does that apologies something?

 

But, I was precise (good old German style) and talked about picture sharpness, not overall picture quality.

Since I don't want you to disappear, I can not provide the link.

But look at what Michael posted and look at the different pages of that website. When I see these Nikon comparisons I'm not so sure that I remembered them correctly.

The filter-removed-pictures look a bit faked, not showing the real clearity that I remembered.

Mr. Like-No-Other, the sample shots on the Hot Rod site are a fake, if you extract the FULL EXIF from the file they've provided, you'll find the comparison shots were taken at different settings.

 

The so-called hot rod camera was deliberately set at a higher sharpness custom setting.

 

Plus, after the original filter is replaced. white balanced setting was completed screwed up. The hot rod shot was taken at a Tungsten WB setting in daylight.

 

Why would we give a damn to a shameless fake? LOL

 

Please don't take my some other comments too seriously, when we don't have a R10 to talk about, this is how we have fun and kill some time ... till next Monday.

Back to discussion on a possible R10 or other new camera from Leica....

 

There's been a little bit of chatter on the Luminous-Landscape and also here too about invitations to Monday night event to announce the new camera. Lot's of speculation about if this is a S2 type or other MF camera or possibly a R10. One of the posters at LL stated that his invitation had a picture of the camera on it and that it looked like a regular 35mm camera. Sounds good too me if true since I have lots of R glass. I'm hoping this is a R compatible camera. I can't imagine Leica being able to bring out both a MF camera and also a new R at the same time (unless they are one and the same),

[doctorlol]

Thought I might pay a return visit to a very favourite website. Nothing has changed, it appears. You are awaiting the coming of the messiah, in the shape of the R10. Yet Canon and Nikon are forging ahead. Having sold all of my Leica R8 kit and lenses and using a D3, I must leave you to your navel gazing, and hope that Photokins 2012, might be the show for the R10. Must say I do miss the 'red dot'!

[mooky]

doctorlol,

I've never been able to give up, or give in yet to another 35 system. I have tried though, and when I was trying, I kept the R equipment put away to give the possible replacement a fair shake - then I eventually sold the newcomer - and went back to the R....

 

Wait til Photokina 2012? No. Or 2010? No. It will be here sooner than that. Good Luck - though - something tells me you'll be back.......

[andybarton]

Amazing how many people who used to use Leicas, or have never used Leicas, are suddenly coming back to the forum to see what's happening here.

Red dots are available as replacement part and are self-adhesive. No problem sticking one on your Nikon....

For Hasselblad, having no antialiasing filter is a crucial part of their „Star Quality“ strategy.

That's what I figured too, they'd only care about extreme quality. I know they don't have one on the sensor but have wondered if there's such a thing (optionally) ever existed. Thanks a lot for letting me know.

I am not aware of an AA filter for any of the current models, even if it was for in-house testing purposes. And I think I would know if there was.

 

But then, doing without an antialiasing filter is pretty much the standard in the medium-format world.

Cool! I'll take 3,ahhh how much?,,i know..... if i have to ask then i prolly can't afford it,

though would love to stick one on my fujifilm s5 that i mostly use with a 20+YO nikkor 50 1.4 in velvia F2 mode.deelishush!.thankfully i kept all my nikkor glass and F3 camera that to this day works without so much as a hiccup,and my dealer sed i wuz crazy selling my R4 that may have been the most defective piece of photograpghic equipment ever sold,and all that R glass that one day may be usefull on a R10?what's that gonna cost,7 D3's? .Heck i'm going to sell my M6 and all my M glass,had enough of paying thru my once upturned nose.

Goodbye Leica,ya were'nt all that.

Hallo,

Look here: Interesting Leica gear

[adan]

Not that I want you to leave, or anything, but:

 

Nikon D200HR

 

Read it and weep folks - AA filters have a horrible effect on not just resolution but also edge contrast and color clarity (read the introduction). If you don't know that you ain't edgicated.

 

Oh - and here's the 5D with and without the AA filter. Eeeeew! Hot Rod Visible

 

BTW I just noticed that this place also does conversions of the infrared filtering - If some brave soul REALLY BELIEVES that the M8 would not suffer image degradation with a stronger IR filter and wants to try it, it looks like these guys could put a stronger filter on for you to try......
