He uses a 45P - Tessar design for the Nikon versus the 50AA....talk about a crippled comparison.You might be interested that Ming Thien compares the Leica MM with the D800.
The Medium Format / Large Format versus Leica discussion has been going on since the 30's. I don't see why Nikon going from 24 -> 36 MP in a Nikon body radically changes anything to be honest and I think Ming Thiens comparisons raises some interesting questions when you consider he's comparing 18 to 36 MP.
Zeiss Tessar design, super centre sharpness. I think the comparison shows both that at a technical level a $3000 camera can hold its own against $11000 of gear. It also shows that 18 vs 36 MP is not a great difference, and of course 36 vs 80 MP is not a great difference so by logical inference, 18MP is roughly equivalent to 80MP. It's not so ridiculous because a 36MP sensor can print at 60x40, an M8 can look great at 20x30 or even larger.
My point is that roughly the same argument has been going on since the 30's and reaching a fever pitch again, why has a 24 -> 36 MP change caused such a change? I guess Nikon realise Leica's clever marketing through social media and this is a full on assault using the same means. They just need a celebrity, Nikon equivalent of Seal and they're done.
Sorry but clearly it's all hyperbole to sell more cameras in market where many people are giving up entirely, using instigram on iDroid to upload pictures of their cat to facebook or switching to things like the Nex7/XPro1.
It's a shame Nikon failed to put the D4 sensor in the D800. That's a real upgrade I could have used. A D4 will also look pretty respectable at 60x40.
Both Canon and Nikon are working on newer versions of their tilt shift lenses.My guess would be that the PC-E 24 would not hold up 100% to the corners of the D800, and also the Schneider would have some problems on the IQ180 (therefore I suggested rodenstock digaron-w lenses).
It's pretty much what I would expect. Sort of how my p45 files compare to my IQ180 files when I start printing large.I'm gobsmacked, to say the least.
I didn't do it myself, since the print shop has much more experience in this than I will ever get, doing this kind of work on a daily basis. I know that they made attempts with at least two different kinds of software of which PS 5.5 was one.>While the result doesn't hold up when studied from up close, it didn't "fall apart" like the digital files
Interesting. How did you upsample the digital files?
Nope. The EF mount has a much shorter register distance than the F-mount, so a converter would require some kind of lens that would most probably reduce the quality.Is it possible to use Canon TS-E 24mm f/3.5 L Version II on D800 with adopter?
Not with an adapter, but the lens can be modified to fit. Rather expensive job and you lose auto apertureIs it possible to use Canon TS-E 24mm f/3.5 L Version II on D800 with adopter?
I'm not surprised. I've played around with some velvia slides testing to print large, and film has through the grain a special structure that can be over-enlarged without looking bad. Yes you see all the grain but it has a nice quality to it showing that this is a photograph, somewhat similar to seeing individual brush strokes when looking close at a painting.While the result doesn't hold up when studied from up close, it didn't "fall apart" like the digital files
Very enlightening Fred - thanks. Are test chart shots like that available for the tech-cam lenses do you know?The progress being made is very significant.
I wonder how the test would have gone with the D800 with the Canon TS-E 24mm on it. Maybe a match for the IQ180 or at least even closer.
Nikons next releases of TS lenses will most likely be on par with Canons current offerings.
I have used this program for years and consider it one of the best upsampling solutions available. In most cases upsampling has to take place somewhere in the stream. The printer driver is the worst case and PS isn't much better. Lightroom doesn't offer the kind of control I would like so I use Qimage which upsamples on the fly and is extremely flexible. This also eliminates the very large files that result from PR7.PS:
Does anyone out there use Perfect Resize 7 to upres photos? It used to be called Genuine Fractals, I think. I wonder how using such a program would influence a test like this.
Results?The IQ180 will be used both on an Arca-Swiss Rm3d with a 35mm Schneider APO-Digitar XL and a 645AF with 35mm Phase One f/3.5 lens.
You are right of course in that going from 24 to 36 is not revolutionary, but I think we still can see on all the MF forums that the 36 megapixel D800E has had a dramatic impact. I think it has broke some sort of psychological limit, we got used to 20-24 megapixels in DSLRs since a few years, but 36 megapixels still has that medium format sound to it.The resolution advantage going from 24 to 36MP isn't dramatic in any way, but a price drop of 60% is.
I would assume these posted corner performances are from "unshifted lenses"? If so, I'd be interested in seeing 5 degree and full shift comparions with the Nikon and newer Canon.Both Canon and Nikon are working on newer versions of their tilt shift lenses.
Canon has already come out with its version II of the 24mm and it is drastically improved.
Here is it's corner performance compared to the Nikon 24mm PC-E.
