Nope, I meant scanned Portra 160; consumer-end ISO400+ film could be beaten by a $80 digital with one metaphorical hand behind its back --- particularly in terms of color quality.

Face it: anyone who aspired for more with film shot medium format or larger. For good reasons.

This one is really good... and here we get to a key truth... When we get into the warzone of ISO above 1600 Digital with all the fighting over noise is better than film.. But we have not replaced all of films ability yet..

Funny, Luminous-Landscape themselves disagreed back when the Canon D60 (note: not the much later 60D, the early 6 Mpx camera) was first released.

Image quality is every bit as good as that from high-quality film scans, and this is now the case at just about any print size you'd care to make.

Oh, and your first source appears to have been comparing processed JPEGs in the case of the digital camera, which might explain the apparent difference. You do not pixel-peep JPEGs. Ever.

That one's a tad more interesting. Let's disregard resolution since whoever did the comparison seems to have picked a rather informal test, with enough focusing and movement inaccuracies to hide any difference inherent to the mediums, and focus solely on DR. Does 35mm film hold more DR than digital sensors? surprisingly, the answer is "depends on how you define 'DR'". Read this fine article on DxO's methods, for instance, which has a section dealing with that specifically:

http://news.cnet.com/8301-11386_3-57415777-76/how-dxo-labs-tests-hot-cameras-like-canons-latest-slr/

But long story short: film holds detail over a longer range, but digital holds usable detail over a longer range. Extreme shadows and extreme highlights on film are barely good enough to provide a gentle roll-off.

A57 is a different generation of sensor with a different filter scheme too. It would be silly to make this an exampled in the discussion just check out the A77 to A57 shots I posted earlier today from the DPR studio shot.. where the a57 has a 1-2 ISO stop advantage at the top of the scale.

DxO states differently --- in fact, they rate the A77 slightly higher --- and they conduct tests over normalized RAW files instead of whatever the camera says its nominal ISO is.
