• UPDATE



    The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being.

    I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure.

Yongnuo strikes again: 100mm f/2 for $170

MTF Charts look comparable.
Q: how do the other Yongnuo lenses perform AF-wise? Are they Canon-like or Sigma-like?

To my knowledge, they started cloning no-AF-tech-listed lenses, like the old 35mm f/2 or 50mm f/1.8 II, which used the old squeaky / slow AF motors.

This, however, is a USM lens they are cloning. Yongnuo even had the gall to clone the gold/bronze dashed 'Ultrasonic' line on the barrel that the 90s USM lenses had on theirs -- but we have no idea how this Yongnuo one will perform.

I don't really follow their reviews, but FYI from Brother Kai on the 50mm prime they sell:

Looks like the EF 85 f/1.8 USM is next on the chopping block for clone next year (released 1992), it needs an update. Seems like it takes a YN copy for Canon to update it.

Maybe Canon will get the memo this time around and update it, before YN copies it though.
Too late. It looks like yongnuo has already copied it.

Just waiting for the Canon Defense league to explain to us, that "knows it all best" Canon and their market research clearly shows an update of EF 50/1.4, 85/1.8, 100/2.0 not necessary until 2029 ... at the earliest. ;D

Yongnuo has knocked off another older Canon lens, the 100mm f/2 USM:

looking at those images I'd be wanting to examine the coatings.

lens reflections shouldn't, on the whole, be white but it could just be the way the images are taken.

anyway I'm very happy with my canon one.

As a member of the Canon Defense League, let me say the following: COME ON CLONED 800F5.6!!!!!!! I'd even settle for a "cloned" 600F4 :)

Ok, I will explain it to you after I finish explaining why there is no market for a 150-600mm zoom lens and why Tamron was wrong to introduce it... a how despite it becoming their #1 lens for sales volume, there was no market for it :)

looking forward to reading your explanatory CDL posting ...

;D ;D ;D
Ok... here goes...

Canon misjudged the market demand for mid-priced lenses. They have high end lenses for big bucks and kit lenses for low budget prices, but the middle ground is wide open, and that is why Tamron and Sigma are dominating the middle ground.

Rather than the CDL league, perhaps your earlier comment was aimed at the CBDL.... (Canon Blind Defense League) :)
