Why? Have they not heard about the high end Canon super tele lenses? Following some of the wildlife/birding fora and I learned by means of seeing many images, that the Canon 400mm f4 DOII is a fantastic lens that turns into a still spectacular 560/f5.6 and still very good 800mm/f8 with both extenders, while keeping below 2,5 kg weight. It is no competition to Pentax, because Pentax does not make such a lens (in that class).
Originally posted by UncleVanya 1) Given that the 7Dii is a worse performing sensor than the plane old K-3 - is there news in Canon land that indicates they are making big improvements that will reduce this delta between the Canon and Sony APSC sensors?
The Canon sensors have kept me away from Canon so far, but with the latest Canon FF sensors, things are (somewhat) looking up. Still not Sony level at all though...
Originally posted by UncleVanya 2) Why Canon not Nikon? Nikon seems to have the upper edge on sensor and focus vs. Canon - at least from my perspective reading about them. However I don't shoot birds. Is there a special benefit to Canon over Nikon (or Sony etc) that applies here?
I thought hard about the new Sigma 500mm f4S with a Nikon D500, but as I explained in another post, portability is becoming more and more important to me. The difference is 1 kg with the Canon lens and still 800 gr. with Canon lens and 1.4ext. I cycle and hike in nature a lot, and I have found that the DA560 + K3 and bag was just above the critical limit, meaning fatique etc...
Originally posted by UncleVanya 3) You mention portability - m43 seems to be quite capable and has some lovely telephoto lenses - and in some cases can even Autofocus Canon EF lenses - sometimes as fast or faster than native use. The crop factor and the 20mp sensors seem ideal for this and shouldn't be worse than Canon on the latest generation of sensors for low light and bit depth. (Assuming there is no massive upswing from Canon in their sensors over past trends). Is this on your radar at all?
As an ex-Olympus user, that had three SHG Zuiko lense, I can say that I will personally never go to the 4/3 sensor again. Not meaning to bash the wonderful new m4/3 Olympus system, but no, not for me. It is either APS-C or FF.
