  • Much improved, apparently, but still a slight compromise over non-DO lenses.  I'd also be wary about susceptibility to lens flare and handling of starbursts when shooting lights stopped down if ...
  • Yes, a CP can help with glare on glass, plus water, metal, or any other shiny surface for that matter.  I personally mostly use the higher end Hoya Pro filters (the thin screw in ones) because ...
  • Replied in Erm, no...
    A guess based on the list, but maybe confused rectilinear with parfocal? Andy
  • One other thing that keeps cropping up is for real estate shots; 11mm can make spaces seem vastly larger than they are, so even though a wider angle might be sufficient to get it in, the extra ...
  • On the specs, sure - particularly so at the long end of telephoto zooms in my experience. On the patents for the lenses however, not so much - the 11-24mm being a case in point. Assuming this is ...
  • Yeah, that's pretty much it.  You get gel filters as sheet like thick celophane, cut them to size with a sharp knife, and then drop them into the slot at the back before attaching the lens.  You ...
  • Courtesy of DCI via Northlight : (1) Lens arrangement 16 sheets group 11 (2) 4 aspherical lens (large diameter grinding aspheric single, large-diameter glass molded ...
  • Possibly, but how many mm of the Sigma 12-24mm do you lose when you apply distortion corrections to *that* lens.  1mm?  2mm?  3mm, even?  Assuming the Canon out performs the Sigma (likely) then ...
  • That's certainly my hope, although Canon's WAs haven't exactly been best of breed historically I think they know this one has to be something special and wouldn't be releasing it if it were not.  ...
  • More likely they've done their homework and have priced it to maximise profits.  Reducing the price might allow for more unit sales, but perhaps not enought to offset the lower margins that would ...
  • Absolutely this is a specialist lens.  If you are thinking of getting this just to "get more in" then, except in a few rare circumstances and some astro or weather photography, you're missing the ...
  • Where available I use the RRS replacement feet for all my telephotos and find they work very well for me. The length is there so you can get the correct balance; there's can be quite a large ...
  • Subject tolerance is definitely something to take into account with wildlife and does indeed vary from region to region - often quite considerably depending on how the animals are treated by ...
  • +1 to this. Maybe start with a general forum like Zeisschen suggests, then break out specific vendors/models once they have an idea of how popular it is. Kind of loosely related, but a...

  • Maybe they are waiting for an official press release with more details in? Most of the DPR announcements of that kind seem to be the official PR texts rather than ad-hoc reporting.

  • Apparently, Canon (and presumably other manufacturers) allow for a little imperfection here and adjust this via a setting on both camera and lenses. In Canon's case think this is a scale that runs ...
  • I've used the 8-15mm for conventional nightsky and aurora shots (plus some severe weather stuff when it can get pretty dark too) and not had any technical problems, but that was with the 1DX so I ...
  • Don't forget that the 24mm is also a 35mm with the 1.4x TC.  :) I'd say it depends on what kind of architecture you shoot, and how grand they are.  The 17mm is generally seen as having the edge for ...
  • Replied in To clarify...
    Gah, I go away for a few days and huge misunderstandings ensue... To be clear, I didn't mean change the laws of physics, I meant exactly what I said in the second paragraph; a range of even higher ...
  • Looking at that quote again, and especially the "We want to add one line to our EF lenses" part, I'm leaning even more towards that meaning an "L+" range of lenses designed to try and counter the ...
