JNR's recent activity

  • Agreed regarding margin limitations of the heavy art papers, but most everything you are likely to use will work very well if you opt for the standard matte setting as long as you provide at least ...
  • Totally agreed. I go months without printing - spending time in two different states. When I have printing to do, I often group a few projects together in the span of a day or two. The Pro 100 ...
  • It is flirting with disaster, but after getting the red X I tend to check the cart sponge for ink then do an extra print or two (unless doing a large print at that time), and will replace without ...
  • I wish I was so disciplined, but that will be mostly wishful! I sold the original film 40mm pancakes way back when, and it was really poor - especially regarding contrast - compared to those lovely ...
  • I think it is quite clear that the XS is the same optical design as the Ltd version, but the precision build (and most likely the coatings) of the latter will tend to give you slightly better ...
  • It's an excellent point regarding exposure and saturation, although I'm not quite as enthusiastic regarding the Sigma 17-50. My copy is pretty close to spot on, but I have found various lenses ...
  • Because landscapes and brick walls are not the same thing for most serious photographers, and the better Raw converters deal with moderate CA and so-called distortion very well.
  • Though I haven't used it in years, the RawTherapee lineage is very good. I haven't used DxO, but I know it is a very good performer based on images and reviews. It isn't at all difficult to match ...
  • While pretty much everyone agrees that the Silkypix-based software packaged with Pentax cameras is better than average compared to the other free offerings, very few folks who test out any of the ...
  • You've got it - just how I see it. The K1 supported only with two re-branded zooms and now a very conventional prime; makes it hard to compete. The 645d then the 645z shows how Pentax can compete ...
  • Alex and Andrew, Agreed that we in the West often discount something that appeals to non-westerners. I have nothing against the K-S1 - and the "lights" opposition seems way over-played for an ...
  • That's what I would have guessed. It wouldn't be worth rigging, but just wanted to mention that some folks have "made it work." If I was shooting a 645z for a living, I wouldn't even try. At the ...
  • All valid points. We have seen some fairly wild swings with the K-01 and K-S1. These are products that were jangles rather than product line strategies aimed at a long-haul vision. Even the K-1, ...
  • True, but a renaming workaround has at least some advocates. See: https://www.pentaxforums.com/forums/48-pentax-medium-format/309281-modify-pentax-645z-dng-raw-files-capture-one-9-a.html Capture ...
  • The real problem here is lack of imagination and inability to carve out a niche. Pentax as a brand has succeeded when it provided a unique and appealing product. Things like compactness, IBIS, the ...
  • Valid thoughts, especially when you think of the flexibility of modern sensors. On the lens front, though, I often opt for 2/3rds stop down to get maximum optical quality in low light situations. ...
  • No question about it that was the setting - if you set it to half-stop steps you would get the more familiar f/1.7. The only reason to set to half steps, AFAIK, is to nail 1/180th for flash sync ...
  • Correct. Something odd happens quite often with variable aperture zooms on the more recent Pentax bodies where the ROM gets confused and does not pick up the intermediate value - reporting a wider ...
  • I get exactly what you are saying regarding the brain's inability to calculate any lag at a certain point. This has come up regarding pTTL discussions where proof that the lag between the ...
  • Lens length and weight favor the OVF, at least in the past. No idea if lag has been entirely eliminated in the better EVF, but they seem to get better all the time. Format is another factor. ...
