Originally posted by Art Vandelay II I spent 2 hours in B&H today comparing virtually every camera between $500 to $7000 USD and I have to say the K7 is my favorite aside from one serious problem; the view finder. In-fact it's so bad I will never buy one because of it. The worst part about testing it out in B&H is not that it's just small and dim compared to full frame cameras (I expected that), it's that they have the K7 located right next to the Olympus E-3. There is no reason the E-3 should have a brighter viewfinder (smaller sensor and all), but there it is on full display. It really makes the K7 look awful when compared side-by-side. Erogs, the K7 wins hands down (and that goes for every single DSLR I tested), but as far as the view finder goes, it's not only worse than the E3 and every single full frame camera, it's also worse than the D300 and the Canon 7D (as much as it pains me to say it, the 7D is an amazing APS-C camera, best Canon ergos ever).
I have no idea what's coming after the K7, but I do know they need to fix the peep hole problem ASAP.
I was very interested when the E3 came out. But the VF was a disappointment, thought it is the best 4/3 VF to date. Even the Sony A700 had a better VF, eventhough it really is noting special, and not even 100 %. The E3 may have a bright finder, but it is still too small compared to APS-C crop. (I have not tried the E30)
The best crop VF, IMO, is on the Nikon D300; (haven’t got any personal experience with the K7). They purposely made the K7 finder good for manual focus, btw.
And I find the VF on the Eos 1D Mark III, better than the original Eos 5D.
A FF Pentax, could be named K-LX
Having said all this, I find the specs really good on the E3, and they pushed the boundaries with that one. And it should be good in the field. Eyepiece shutter is something I hope Pentax puts back into their cams at some point.
Originally posted by *isteve A good 100ISO film scanned at 4000 DPI compares well with 10MP digital equivalent.
Digital cameras vs. film, part 1
However, higher grain can improve accutance which creates an impression of sharpness
at normal viewing distance, even though it does not actually represent higher detail levels. It will however make texture look a lot more "gritty".
A Pentax K7 will produce slightly more resolution in real world conditions. It will look a lot cleaner at ISO100 and for that reason will be able to handle more enlargement, but film may well appear sharper on an A4 print unless looked at through a loupe.
A 21MP 5Dmk2 will resolve far more detail than any 35mm film.
When we get to higher ISOs, digital starts to leave film behind quite comprehensively.
The size in MB of a scanned film is not relevant to its actual resolution. Its just a reflection of the scanner resolution. To avoid grain aliasing, its a good idea to use a scanner with at least 2X the spatial resolution of the negative, so 4000 dpi is a minimum. Ideally you would use a 8000 dpi+ wet mount drum scan which would get you slightly more detail and less grain boost, but its not very practical.
Comparing 4000 and 8000 dpi scans Thanks for the links.
So you're saying, adding grain can make the image look more pleasing to the eye ? I remember reading some top specialist developer, who always added grain in the end, to digital pictures.
There was also a good thread by Pål, on texture in film, vs. digital
