Win a Pentax Limited Lens: Raffle Now Live!

Looking at that first sample photo in the K-1 review (Pentax K-1 Review - Sample Photos | PentaxForums.com Reviews): a photo from a rocky, dry place in the US (perhaps Arizona?) taken with this setup: FA* 85mm, F:8, 1/30s, ISO 100 (pixel shift) makes me think about how the 67II would fare, say with an equal setup: 165mm lens at f:16 (?), 1/30s, ASA 400 film (grain equal to FF 100 ISO?)
I downloaded the RAW file (8bit, 7360X4912px at 240dpi, 177mb) of it and compared to some 400 ASA shots I have, but I havn´t really done desert shots with 67II? Would anyone (desertscape/Steve?) here have a sample? It looks to me like the 67II would still hold it´s position on the K-1, but that you have to do your absolut finest photography. Still looking into it. When scanning at 2400dpi at 300dpi with the Epson V750 I get files with that kind of qualities and my guess is that a high level drum scan would still be better than the K-1 sample.

67II with the SMC 67 4/55 on TMY400, close-focus at 0.35M

100% crop


20% jpeg from the original 6653X5280px, 240dpi, 38mb file that has a print size of 56X71cm

Why would you not compare them with 100iso film in the 67II?

Because the film area is ca X4 and enlargements thus equally smaller


note: it´s about the difference of size in cross section, isn´t it, but in principle

Batman and Robin. Im gonna go for that "dynamic duo"! Fielding all that glass, makes alot more sense with the great combination of the P67II and the K-1—than it does with the (APS-C) K-7!

Regarding sharpest images taken with the Pentax 67, my sharpest isn't exactly a landscape. It's an F5e Tigershark on static display at an airshow I attended a couple of years ago. The lens was a 45mm. I was shooting Tri-X and it was a bright, sunny day, so using the Sunny F/16 Rule, this means I was shooting at either 1/500 at f/16 or 1/1000 at f/11. So the shutter speed was plenty fast enough for hand-held photography.

If you look closely, you'll see that this jet is displaying a Star in addition to the typical US insignia. Reason? This is one of the aggressor aircraft from the US Air Force's Red Flag training program. The star is red, in imitation of Soviet markings.





I scanned the above image at 2400ppi with my Epson 4990. The full-size image was downsized to 1600 x 1282 for display on the web. It is then further reduced by the forum software to be displayed here. You can see the 1600 pixel image here:

The 45mm provides great depth of field, so basically everything in the photo is in focus, or close at least. Anyway, it's a good way to evaluate sharpness. I think the 45mm is a real winner.

Hello Michael, how are things going in Houston? All that water you guys had! Yeah, that 45mm looks great! If you still have that 2400ppi scan in full resolution, it would be interesting to see a 100% crop sample, so we could compare directly. About your subject/motif: I´ve seen recent photos from Syria of modern USAF jets in russian colors and insignia and right over our heads, here in Scandinavia, we have NATO-RuAF show-offs, very real warnings and simulated "dogfights" going on. Very scary indeed!

Hey JT, thanks for asking. Houston got hit really hard by the huge amount of rain that fell here. It is now being regarded as an 800-year flood. There are places in the city that are still flooded. Fortunately, our house weathered the downpour without problems. We were stuck at our house because of flooded streets for a few days, but that wasn't a problem for us.

I took the above two photos and made 100% crops from the 2400ppi Epson scans. I think that, by and large, resolution has held up reasonably well. You be the judge. I didn't do any other manipulations to the images.

You know, thanks to the first crop above, I just realized my above "Red Flag" comment is erroneous. Why? Because the rank of the pilot stenciled below the canopy is clearly stated as his being an LCDR. LCDR is a US Navy rank -- Lieutenant Commander -- so this means these F5s are aggressor planes flown by the Navy's famous Top Gun school. Eh, Red Flag, Top Gun, they're all the same . . . right? Hehe.

I had assumed these two F5s were from the AIr Force school since, that weekend, the US Airforce Thunderbirds were performing their aerobatics for the crowds at the show.

Thank´s for producing/posting the crops for comparison! Ain´t it nice to see.
