  • How much "better" are other companies 18-250 lenses? If you shot identical images with those 18-250 lenses and the DA 18-135, would anyone be able to tell the difference in 24" prints? Are the ...
  • Replied in Photokina?
    Sorry, not going to happen (it would be too heavy and expensive in any case). More likely we'll see: HD DA 18-70 2.8-4 HD DA ~150-~450 f4-5.6 Maybe HD DA 12-28 f4? I think we'll see the 70-200 f2.8 ...
  • There are compromises involved with the 40-150 as well. It's just a consumer grade zoom lens, and compromises have been added to keep the cost way down. There really isn't that much difference ...
  • I have both the Panny 14-45 and the Olympus 14-54 mk1, both of which I have used on an EM-5. While one can praise the Panny 14-45 for reasonable sharpness across the focal range, I never warmed to ...
  • Yes, but it's more challenging. Little if any professional service. Fewer choices in high-end/specialty lenses. No high-end action/sports cameras. Inferior flash system. Fewer accessories. You can ...
  • I would add the DA 15. It's the best of the lenses on your list, and probably the best overall wide angle lens available for Pentax APS-C DSLRs.
  • I'm expecting the announcement of two new K-mount lenses at Photokina: 1. The telezoom: HD ~150-~450 f4-5.6 2. Standard zoom: HD 18-70 f2.8-4 I suppose there's a slight chance that the wide angle ...
  • 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, ...
