  • Given that the four-thirds 12-60 weighs 575 grams and sells new for $999, is it realistic to expect a 300 gram m43 version at $500? Would such a lens even be possible? How much smaller could an ...
  • Replied in Just 1 Lens.
    That would be wonderful but it's entirely unrealistic. If you want to get weight and size down, you'll have to make compromises in terms of focal length and aperture. More realistic: 14-54 f3.5-4.5 ...
  • Assuming you stopped down to about f8, I doubt you'd see much difference in resolution between those two lenses. But I would expect the A 28/2.8 to have better microconstrast, better color ...
  • I picked up a 14-54 mk1 a month ago and have been using it quite a bit with the EM-5. My only complaint is that the lens is a bit large and heavy for the EM-5 (I wish Olympus would make a slower, ...
  • I agree that the best modern lenses tend to be better than older lens, but "far more pleasing" is a bit of an exaggeration. Two problems here. To begin with, the DA lens lineup is hardly of date. ...
  • Replied in Infrared help
    I'm using a 665nm filter, which allows a little more visible light to creep in than the 700nm. That provides a little more data to work with for false color IRs. I swap the blue and red channels ...
  • Replied in Infrared help
    To start out with, you need to be getting fairly decent white balance readings on your camera. I find that the AWB on my IR converted Olympus EPL-1 works fine; but that's not necessarily the case ...
  • Maybe. But perhaps a more plausible explanation is that some people are more uptight about edge to edge sharpness, and tend to make a big deal about small differences in resolution. While the 9-18 ...
  • I never had any major issues with corner sharpness of the A 35-105, provided one stopped down a bit. However, the A 35-105 is not going to quite match any mid-tier or better modern zoom glass. ...
  • Pentax does not believe strongly in MTF charts. They believe that lenses should be designed to produce images that are aesthetically pleasing to human perception, rather than merely score well on ...
  • I have a DA 17-70. I also have the first version of the 18-55 (I've had it since 2006). I can't imagine any situation were I would want to use that 18-55. The only reason I still have it is that ...
  • They could be old stock Ricoh hasn't been able to sell off as yet. The 17-70 is, optically, a very good lens, but it's been plagued with issues relating to AF/SDM and lacks WR. The new ...
  • Most people tend that edge to edge sharpness is the most important metric, perhaps the only metric, for judging a landscape lens. But I don't happen to think that's true. Sharpness is important, ...
  • There may be a lot of m43 lenses available, but there's also a huge amounts of duplicates. Scores of compact consumer grade zooms, and soon there will be two sets of pro quality zooms covering ...
  • There isn't a whole lot of difference between them. The 14-150 has slightly better microcontrast, giving images a tad more pop. In the 40mm to 50mm range, they are about equal in resolution. The ...
  • That could be right in the sense that very few people would buy the lens, but perhaps that has more to do with deep seated prejudices of consumers who are still laboring under prejudices inherited ...
  • This lens can only be preordered. It's around $500. It's also quite large and heavy (~600 grams) -- heavier than any current Oly or Panny m43 lens. The lens is designed for, and makes more sense ...
  • I also have a converted E-PL1, and none of the kit zooms I have tried with it are all that sharp. The Panny 14-45 is the best of the lot; but there's no way you're getting tack sharp images out of ...
  • I got the 9-18 because of price, size, and filter threads. I've seen large resolution samples of images from the 7-14, and it's definitely sharper, particularly in the corners. However, the 9-18 ...
  • They would be way too big (and expensive) for my uses. I'd prefer a slower more compact zoom with longer range, something like a 12-70 f4-5.6, but with professional optical performance, rather ...
