I think the biggest grievance people have had with this test was that ISO 400 was used and the type of film used was not specified.
That said, you can get cleaner images (i.e. less grain) from a high end digital SLR at like for like ISO than on 35mm film. It might not be the same case at ISO 100 (e.g. Provia 100F, Astia 100F or the new Ektar 100) would probably still pack a punch. If they had used 120 format film even with 6x4.5, I think the differences would have been increasingly minimal.
But of course, not many people will print that large (most people are happy with 6x4s, and looking through my grandparents photos, most prints I have found are straight 120 and 127 contact prints! And people were happy enough for the cost with those too! Staggering to think that!)
I like grain sometimes and this is why I continue to shoot film, with the right film for the job. With PanF 50 and even Tri X I have on occassion printed 16x12's and even a couple of 20x16s which were very acceptable for the Pan F and still decent on the Tri X (grain was evident but that made the picture to me.)
So I say don't take it personally. At the end of the day this was The Gadget Show, not "The Second Hand Real Steal Show" -- most people would still 'get away' with a Nikon F5 and chuck out very pleasing results, it might take a bit more work but the camera as ever doesn't really make the photographer. I won a local competition 2 years ago for a photo I took on a throw away camera! It baffled many including me!
At the end of the day, it always come down to your results. Are you happy with them? If yes, then that's the main thing. I certainly enjoy my photos with my "out of date" cameras as do others. What fills me with the greatest joy is that excluding glass, on what I spent first on an EOS 5 some years ago (5 years ago?), then an EOS 3, followed by a Mamiya C330F, an Olynpus XA and most recently a Leica M2 - I have spent only half of what I think a D300 would cost (£615 is what I have spent) -- and with the pleasure it brings it makes it all the sweeter 🙂
I know my consumption of film does begin to add to the cost but that's one of those things that I accept perhaps like a classic car owner accepts that running costs might be higher than buying a more recent car.
To me, the photograph is the most important thing and I'll enjoy a good one whatever the process.
