A Canon RF 70-135mm f/2L USM gets a mention [CR1]

An unknown source is claiming that Canon is actively testing an RF 70-135mm f/2L USM with a very small group of photographers and videographers.

The same source claims that this lens will be announced in Q4 of 2020.

With IBIS coming on the Canon EOS R6 and Canon EOS R5, it makes sense to leave IS out of this lens design, anything to save a bit of size and weight will be welcomed.

This lens has been previously mentioned,but I caution that both of these reports come from unknown sources.

The Sigma 50-100/1.8 is for APSc and it's 1.5 kg. Scaled up to 70-135 FF means it will very likely be HEAVY, even for mirrorless.

Sigma is well known for building lenses with an excessively large front elements.
A 75-130/2.0 lens with front element as small as 67mm is a possibility. Let’s see what happens.

wow! Would probably be a beast! Not my kind of lens I think (i'll get the 70-200) but for portrait photographers it could be a winner

I could think of many ways to use this.

despite likely chunky heavy beast it's still going to be lighter and more compact in my kitbag than set of 85, 135 and maybe 105 primes. Compared to small 1.8 variants it's a better option and likely higher performance so wont miss much short of splashing for faster higher end primes. On that note probably same price tag as a single faster than 1.8 prime in that kind of range so I think this has a place in many portrait folks bags.

and the 28-70 has a 35mm lens diameter ;) dream on man - dont think it's a problem though very exciting lens - curious how much better than the 70-200 it's going to be.

This is on my definite buy list. I would love to run a f/2 trio: RF 28-70mm; RF 70-135mm; EF 200 f/2 adapted would cover a lot of ground for me. For some reason f/2 really seems to get me over the hump for most of what I shoot.

1. 28-70/2.0 is a normal zoom. The 28mm at F2.0 dictates a necessity for a larger front element. Not the long 70mm end.
2. 70-135 zoom range is a bit different in that vignetting is not such a huge issue as with 28mm end of 28-70
Sure. Having a large front element would improve sharpness in mid frame and extreme corners, reduce vignetting wide open

but read my statement again. Front element could be made as small as. The question remains how Canon engineers view optical quality vs size / weight issue.
i would think that 82mm front element would be adequate.
