  • I usually don't much care about "me too" posts. Having said that: well done! :-) As some others, I would also like to see some additional photos with your new speciality lens. Kind regards,- Henrik
  • You're welcome. I's like to add one thing, though. I wrote earlier: "But, remember, if you're shooting cathedrals or other non-moving objects, you can shoot at upto 8 times longer exposures with...
  • There exist no APS-C zoom lenses that would let in as much light on the APS-C sensor as any f/4 FF zoom lets on a FF sensor. While an f/2.8 APS-C zoom lens is twice as bright, the sensor is below...
  • It's a lens flare, and a mild one at that. You'll get one or several, in one or all the colours of the rainbow, or even more spectacular effects, with any lens in such a situation -  particularly...
  • Lbr0805: Future compatibility is something "someone" should have thought of when it _chose_ to make its creations using a proprietary, closed format. That was that "someone"'s choice, and it has...

  • Your images look just like the 50/1.8 does when shot wide open: somewhat sharpish in the center, very soft at the edges, and everything out of focus is somewhat dreamy, and high-contrast edges even...
  • Not strange at all.
    1) An f/1.8 lens gets the same light intensity on all sensor sizes. This is obvious, because the same f/1.8 lens will be equally bright regardless of whether you put it in front...

  • I also have used the lens extensively for e.g. night sky shooting. For that it is very practical. However, for insane perspectives, it's just pure fun! :-) Kind regards,- Henrik
  • To F-Jo: Dust does NOT accumulate on the sensor, but on the anti-alias filter which is some distance from the sensor. Because of this, the smaller aperture you use, the better dust shows. This is...
  • Hi there! I just wanted to say that I still get surprised by the insane perspective you can get with a full frame camera and the Samyang 14mm f/2.8 ED AS IF UMC when you put your heart to...
  • Suggestions to DPreview:
    1) You really should add sensor size on the highlight features of every camera (in mm x mm). And put it first, or at least amont the megapixel line. I my opinion sensor...

  • Yes.All Canon EF, EF-S, and TS-E lenses are fully compatible with Canon 450D.Kind regards,- Henrik
  • Replied in New 80-400mm
    The Nikon is a 2013 lens. The Canon 100-400L was released in 1998, in other words 15 years ago. A lot has happened since then. The 100-400L is a nice lens, but its image stabilization is of the...
  • I honestly don't know of which aberrations I should pick from. If you have a claim to make, please make it, and don't keep us guessing what you might or might not meanOf course, if you just intend...
  • Why do you think stopping down wouldn't help? The very first post in this thread shows coma decreases when stopping down to f/2.0, and vanishes completely by f/2.8.I've shot some auroras with the...
  • I'm afraid you didn't check LensTip, which routinely tests both coma and astigmatism. The relevant page, which shows pretty much the same come info you presented for the 24/1.4L II, is here.When...
  • cyberstudio: They didn't say "aperture increased from 1.4 to 1.0", which would have been be fine. But saying that the F-NUMBER increased from 1.4 to 1.0 is incorrect. The number 1.4 cannot increase...

  • If you want to buy one lens for your first FF camera, be it a 6D, 5D or 1D family camera, 80% of the time that lens is the 24-105.The 24-105 on FF is everything and a little more than the 17-55/2.8...
