Hands-on with new Canon RF 100-500mm, 600mm and 800mm telephoto lenses

Jeez, 'expect slower aperture' was right !

These new 'supertelephotos' from Canon are more consumer orientated rather than the 'big white' we are waiting on.
Try f11 ! and fixed at that.
The lenses are also collapsible for storage.

RF 600 f11 IS STM - 200mm long retracted/270mm extended, 930grams, 4.5m close focus.
RF 800 f11 IS STM - 282mm long retracted/352mm extended, 1260grams, 6m close focus.

Interesting that Canon have said in the press release that "Diffractive Optics technology helps to reduce the necessary number of lenses and greatly diminish the cost of the lenses". It seems like a great way to go for lighter, more affordable supertelephotos. I think we could be fairly confident that we will one day see a 600 f4 DO ....... but when !

Prices are very good: 700 $ For that 600mm and 900 for the 800mm. Ofcourse you need good light but I feel tempted if the stabilizer works ok.

The light gathering is comparable to m43 so should be highly useable as a more compact setup - liking the look of that 100-500 too.

But if AF works on the R series then heyho?

I also read somewhere recently that Canon have applied for a patent for a 100-600 RF L lens and a 100-700 version as well!

The f11 lenses may well suggest that Canon is very comfortable with the low light performance of their new sensors.

That's an extrapolation that I took from it too.
I haven't seen any usage reviews yet, but I'd also take it that they are more than happy with the AF ability at f11 too.

If I get to f8, or f9 with my G2, I feel really stopped down, even with our bright light out here. ISO often starts going up into the mush zone on a crop body. Quite interested to see what sort of voodoo Canon have come up with !

With these new 'soccer mom' (as I have seen it described) consumer lenses, I'm not holding out great hope that we are going to see a f4 big white any time this side of the next generational change ...... ~4 - 6 years away ???? Probably in an RF mount. Some things (like the 7D III and F mount supertelephoto DO's) just look unlikely to now ever happen ..... ?

I think Canon is doing something right here (more or less the same that m4/3 did several years ago). Make something that is better than the phone camera and still economically and weight-wise manageable for someone used to the phone. There has to be lenses fulfilling the above that are long enough that you cannot just crop from your phone image to get the same quality. Thereafter hope that a few get hooked enough to invest in the higher priced white whales.
