Could you please post links to comparisons of images taken with different systems.

I've tried to Google this subject but could not find any detailed comparisons or test shots.

What i'm looking for is test shots taken with a Medium Format camera and with an FX or DX camera.

Something like this:

I'm also planning to post my own review of test shots taken with a Canon 5D MKII and with a Medium Format 6x6 camera later on.
 
5dmk2 and P20+ back. Pretty similar. Skin tones are slightly nicer on the Phase, and you can drag it further in post. Out of the two, give me the 5d.

As far as I know P20 has a 36,9×36,9mm sensor. Its not much bigger than 36x24mm sensor size for an FX format. Perharps that's why you found them pretty similar. :thinking:

I tried Sinar 23H which also has a small sensor size I could see a difference but it was not huge...

H4D 50, pretty much straight out of camera, just normal LR sharpening. Skin tones, in particular are vastly improved.I'm not sure what you hope to show from this at web resolution though

The biggest difference is the jump to 16 bit colour.

correct. Yet to get my hands on a higher spec Pxx+ or an IQ....


BTW, teamwork digital have got some good deals on some phase one backs at the moment.... :naughty:
 
Full frame current range DSLR vs old tech barely larger than full frame 35mm "MF" digi-back. Increased sharpness and 16bit advantage is what you'll get, but not by a massive margin. A properly scanned 6x6 and up negative will outperform both, by far...

An expensive polaroid back imo ;) (joke)
 
Old tech isn't necessarily smaller sensors, my Imacon Ixpress 528C (circa 2005) back has a sensor size of 36.9 x 49mm which is just over twice the size of a FF DSLR sensor and although it only has a native 22MP the pixels are large and 16 bit, but the big surprise with this 'older digital back' is that it has the facility to capture still life type images in multi (4 shot) and micro (16 shot) which can give up to a 528MB file.

Probably why on its release it cost $30,000
 
I was referring to the p20 and sinar backs, I'm sure you chose your back knowing it was on the larger size. There's no replacement for displacement :) I wasn't criticising your set up, just saying that the similar results are to be expected with ff dslrs and similar sized smaller sensor "MF" digi backs. The larger sensors and the later backs are just immense, no question.
 
Hey up Danny, I wasn't intending to come across all 'protective like' of my kit, I was just meaning that people shouldn't dismiss older MF digital backs if they get the chance to buy one. I was lucky in that I was offered the chance to buy my outfit at a very reasonable cost.

One day I might be so lucky lol!

On a side note, shoot more film!

I've just found a comparison:

Phase one p30 vs Canon 5d mk II

"...There's just something about the look of the images from the P30+. There's more depth, the dynamic range is better and the colors look more realistic."

Yeah. People liked to say stuff like that when they've dropped 5 figures on a chunk of metal.

"You won't see it in lab tests but the images have a beautiful enigmatic feel to them that's impossible to replicate...."
 
The first comparison shot shows a massive difference in detail retention through the dynamic range, which is obviously miles better in that image in favour of the P30. The 5D looks like it's losing detail in both the shadows and the highlights, possibly noise reduction too kicking in because of the grainy surface perhaps? Looks soft.

TBH they both look edited to me. Which kind of invalidates everything.

That's why I decided to start this topic - perharps one day we will see here a good comparison and a link to originals.

...At least I will be able to post my photos from a digital FX and a Film MF.

I'm sorry to say that above ^ is no representation of what a 6x6 neg and a V750 is capable of, especially on medium speed film like portra 160. Not a dig, just an observation. It's soft and noisy.

I think you are rigth and thank you for direct and constructive feedback.

I bought my Epson v750 recently so still have to manage how to get maximum from it and these photos are probably soft because it was f/3.5 handheld at 1/85 -1/125...

I'm still waiting for my negs from a Lab - will post some more photos when I receive them.

Problems with scanning its a part of the Medium Format on film ...

Scans from an Imacon look much better:

I'm glad you took it the right way fella, I only mean that you can extract much more from your equipment so have fun getting used to it and working at your workflow. I assume you're using silverfast ai?

Yes, I'm using Silverfast AI. It comes with the Epson 750 scanner.
I'm still trying to figure out what profile is better for the New Portra 160 and I still haven't tried Silverfast HDR sofware.
 
I know it comes with it that's why it was a safe assumption lol. I haven't worked with silverfast, I use vuescan and epsonscan so I'm afriad I won't be any use on helping you figure out your settings.

I'll do some researching for you and see what I can come up with, it may help :)

Thanks! I actually don't mind to try Vuescan if its as good as Silverfast ...

I've just checked your portfolio there are a lot of realy good photos.
Did you take all of them on your Mamiya RZ67? Are there any photos in your portfolio which you took on Film?
 
I'm not sure that it's as good, I think it's supposedly alot more user friendly though. The UI of silverfast is supposed to be a little on the difficult side to master. Download the vuescan trial and see how you get on :)

Thanks very much, I do try! All of the black and white shots except one are shot on film if I remember correctly. The colour photographs are all digital so far, this will change in the next couple of weeks, currently shooting a fair bit of colour 120. They're all with the RZ67 :)

I found another interesting review:

Phase One P25+ vs Canon 5D Mark II
Click to expand...
Hmmm... I have to say I'm not sure what that proves. Other than the colour rendition is different between the two cameras (he says the MF is the "correct" colour) and apart from the last image which is comparing a 1DsIII to the P25+ there seems to be very little in it.

BTW, another important factor is that 25 on sharpness in ACR is too low a setting for Canon. It produces a slightly blurred image as it doesn't counter the AA filter enough and is just Adobes default setting (which doesn't mean it's correct!!). You really need it set about 50 for a 5D2 IMHO. Would be interesting to see the same comparisons with this as the default sharpening in ACR (I know the RAWs are there, but I'm not going to do it!).
