I can go from 16mm to 1600mm, what do I win?

This is becoming so humiliating!
I'll buy the 1200mm + 2X extender. Eat your heart out you-future-losers!

You beat me, mine is from 15mm to 560mm.
Life is so unfair!

I'm very interested in the 10-20/4, Neuro. You are the go to guy for knowledge. How do you like the lens? Thanks.

It's a seriously fun lens!

I'm dying here! So many great lenses, so little

All you need is a gun and a face-mask...

I've got 28-200 covered, mostly with Takumars. Tamron 45mm, Canon EF 135, lots of m42 mounts.

No RF.

You are right. Not fair!

When I go out to shoot birds, I now bring only the supertele. I used to bring along a standard zoom, 'just in case', but after a few years of never using it I no longer bother unless I know there will be landscape opportunities.

However, when traveling I am always opportunistic. I bring the 10-20/4, a standard zoom (typically 24-105/4), the 100-500L or RF 100-400, and several lenses in between...usually a TS-E, a fast prime for indoor shooting, etc.). I bring several lenses in a carryon, but use a shoulder bag with a subset of them for any given outing.

I recognize that. I used to go with a 14-35, 24-105, TS-e (Rogeti frame), EF-70-200, 50mm, filters (LEE), tripod and... well.
But now I want to travel lighter. I have a new Think Tank Photocross V2 14l sling bag. And I fill it with the R8 and the lenses I mentioned. There is also room for a 28mm f/2.8 and a 50 f/1.8. Furthermore, screw-on ND filters 6 & 10 stops and a polarizer (67mm). Travel tripod. And off I go, prepared.

Such a challenge is nothing new to me. One lens on the camera with which I do all the photography work. But when I head out and know what I will encounter along the way, I like to be prepared with a bit more flexibility. And 10mm to 560mm gives me a lot of flexibility. Incidentally, I see no need for f/1.2 for myself.

Soon I have a "holy trio" for travelling. It covers 10mm to 560mm. RF10-20mm, 20-50mm (pre-order) and RF100-400 with 1.4x. Pretty light in weight too.

Of those, I've only heard of Makita. I have a nice Makita circular saw, and I once used a Makita reciprocating saw for purposes very far afield from what the manufacturer intended (you probably don't want to know specifics, given that it relates to my forum username).

I cannot help imagining some kind of frankensteineske activity for that poor innocent saw...

Sorry guys, but I only order Makita, Hikoki, Fein or Festool.

I agree! I don't understand how the 'lens business' works in China. What I see is that 'Pergear' is a distributor of several brands (Viltrox, TTArtisan and 7Artisans etc.), but the brands/manufacturers are looking independent to me (or am I wrong?).
A speculation: Who is the patent owner of that 14/2.8 lens design? Can the same - successful - patent be licenced to different manufacturers?

Just look at cheap tools on Amazon, you'll sometimes find 10 "different" brands for the same c**p!
More internet presence?

I don’t understand the marketing under so many different names. You would think it would lower the appeal.

I'm a bit shocked about your having to return an RF 14mm f/1,4 for, I presume, optical reasons.
Anyway, thanks for the warning, I won't buy mine just before my summer vacation as I intended to do.

The copy that I returned was not really a bad copy, but the one that I kept was slightly better. The reason that I bought a second copy was that the astigmatism on the first (from B&H) was worse than I saw in other posted images, and upon reviewing my images in more detail, the astigmatism was worse in the upper left corner compared to the upper right. Test images shown here, including some ISO 12233-type chart crops.

The moral of the story is: always test your new lenses!

Indeed. I had a Rokinon 14/2.8 for EF, which was a good copy that I got after returning the first one. That's only one of two lenses that I've returned for a better copy (the other being the RF 14/1.4L VCM).

I'd love to see a matched set of 24-70 f/2 and 70-180 f/2. Why stop at 180? Because it would still be compatible with 95 mm filters. Otherwise, 200 would be fine. I realize that you could use a rear filter gel setup but for the purposes of such a lens, being able to swap out filters and dial in a polarizing filter would be most useful.

probably it would be huge and heavy. 70-150 f2 would be suffice for most people and it will be manageable.
