There's nothing really new here, but once again we see 5 unreleased lenses show up for certification according to Nokishita. We suspect at least one of them is the RF 100-500 f/4-7.1L IS USM. None of these lens SKUs are for the new RF teleconverters either.
Unreleased Canon Lens SKUs (One of these SKUs is the RF 100-500):
- 3986C005
- 3987C005
- 4112C005
- 4113C005
- 4114C005
- 4234C005
I and others expect to see at least 4 lenses announced before August of this year.

An L 500 f: 7.1 lens. I don't see the point, no matter how good the sensors are today
Canon 100-400 is no near as long as Sigma 600
Are you saying that Canon 100-500 will be F5.6 @400mm ? I highly doubt it. My estimation is: F6.3 @400mm, it is going to be a relatively slow focusing lens.
let’s see who was right.
RF 70-135/2
RF 35/1.2

2 slow, cheap primes that I don't care about :p
If you are comparing f/6.3 with f/7.1 here, it is more like 1/3rd stop slower.
But I don't know what the Sigma is on 500mm if that is what you are comparing with?
Yes it is external zooming, it is probably a little lighter than the EF 100-400 f/4-5.6 II and about the same size if you add the EF mount converter to the latter.
this is a good one. I shoot a 500 II, and although that lens is superior in terms of sharpness and 'look', I never ever go on a trip without the 100-400, due to the lightweight nature of the lens. It can be swung around very quickly, whereas bigger, heavier lenses take more time to react to action (and wildlife can be very unpredictable).
I know for low light it's certainly not the best, but with focal lengths of 500mm, I usually shoot stopped down anyway. Sometimes even f/11, also on the 500mm prime.
If this 100-500 can deliver more sharpness, improved AF (although the 100-400 is already very good) and maybe even a tad bit lighter, I'd consider it a very acceptable upgrade. For the real low light stuff and IQ, I''ll keep my 500 for now and see what super tele primes in RF will come.
Once this lens is out, we will hopefully see some comparisons with the 100-400 mm II and Sigma 150-600 mm and 60-600 mm. I would not be surprised if it turns out that it strikes a good balance between these. Not strictly an upgrade to the 100-400 mm but with additional reach and likewise better AF at alower cost and weight that is more competitive with the third party alternatives.
But they need to get this into the hands of lots of people to take pictures and comparisons, because the numbers sure don't look enticing.
Still hoping we might see a 500 F/4 DO or something similar as well.
At least on EF Mount, with 1.4x attached, 100-400 AF slows down. Not by much but still. Thats what, F5.6 vs F8.0? Will see how we go anyway.
1. A small, lightweight 50mm f/1.4 IS
2. A lightweight 16-35 f/4L IS or a 20 to 24 f/2.8 IS prime
But I doubt these will be included in this round. And Canon has had a hate on against producing a new 50 f/1.4 for decades now.
