[Canon Rumors]

New fast primes

The often talked about 50 f/1.4 and 135 f/2 have appeared in a new patent this week. We’ve heard that a replacement to the 50 f/1.4 would come first. A new 135 f/2L is a desired lens if they put IS into the upgrade. We’ve also heard a new 85 f/1.2L with reduced weight and approved AF performance was also on the horizon.

a new 50mm f1,4 will be announced when the old one is celebrating it´s 25 year anniversary.   

only 5 more years...

I still predict we won't see any MkIII lenses until the big megapixel camera is out.


Nice to know they are coming though.

Any experience from the past on how long we may need to wait - as time from "patent detection" to "physical product shipped"?

135 f/2.0 with IS would be awesome ... if they do release it, I hope Canon goes easy on its pricing.

I'm very happy with the replacement of 24-70 f2.8 II + 70-200 f2.8 IS II from Canon.

If this rumor is true, I'll pre-order one of each

RLPhoto will like this rumor. He might wait for BigValue sale though

Only one of the four, the 85 f1.2 is for a MkIII lens, the other three would only be MkII's.

The 135 patent is not IS, indeed only the 50 f1.4 contains enough elements and groups to be IS but it is a stretch.

Your hopes will be dashed!! It will double in price from the current version, for sure.

Don't hold your breath for it.

True, there is a CR1 that we will see rumors about these lenses by the year 2020 

[drolo61]

got the drift, would to nice to be true

[RLPhoto]

If the New 135L is non-IS, fail.
