[5 f/1.4 lenses]

(converted for video are all T1.3)
What?

I think he meant T 1.5 or 1.6. I've yet to seen lens with higher T-stop than f-stop. Maybe some quantum mechanics lens, which is able to bend the law of optics? :)

The fragility of microUSM makes it a complete non-starter for me, personally, and STM is fast enough for a lot of my uses. I'd strike mUSM from that list entirely.

You probably meant Nano USM? What makes you think it's fragile?

He probably meant what he said. Micro USM is what's used in the 50/1.4, which is notorious for AF failures.

Thank you. I had no idea it exists :)

AFAIK only two lenses with microUSM exist. 50/1.4 and 70-300 IS (first one). The latter didn't even have FTM...

Indeed. And ahsanford's post, which I was replying to, listed both microUSM and nanoUSM, separately. My only quibble with nUSM is the price for the 18-135 compared to STM. For the use I'd have (do have), the upgrade isn't worth the price.

It was never a Canon marketing term like Nano USM, it just means USM implemented by means of a micromotor similar to that used by many cheap non-USM, pre-STM lenses and unlike the much more common ring motor based USM.

I think three missing lenses are a 20mm IS, 50mm F1.4 IS and 85mm F1.8 IS along the lines of the fantastic 35mm F2 IS USM, 24mm F2.8 IS USM and 28mm F2.8 IS USM. The 85mm and 50mm would be obviously requested lenses.

I'd love for the 20mm to perhaps be a f/2 or f/1.8 lens (a la Nikon 20mm f/1.8 ) but I wouldn't hold my breath, looking at the 24/28mm f/2.8...

Not to really throw one out there unfounded... but I was shooting some bugs over the weekend, and it occurred that we just saw an "M" and and "S" macro with integral macro light, it gave me pause to wonder if there's potential for a new 100 macro with integral light for EF mount.


Way out of left field, I know. Sorry.

Personally, I'd like one of these new lenses to be the 600 f/4 DO. I wonder why no one here has suggested one or more of the new lenses could be updates to the tilt-shift line? They would seem to fit the rumor fairly well.

Apparently I nailed this one 8).
