Yes it’s slightly faster than the 1.4 on the 100-400 and slightly shorter (500mm vs 560mm) so a bit of a wash.

if it is f5.6 at 400 mm and sharper at 400mm and sharper at 500 mm than the 100-400 II with TC and without -- and lighter than the 100-400 - Isn't it an improvement?

an F7.1 lens @ $2000?  I doubt it, guessing $1500

Interesting also to see the AF speed difference between 500mm f7.1 vs 560mm f8 (1.4x added to 100-400).

if it is not an improvement on all aspects, they will take a beating

so far RF has been really good

can't imagine they would go backwards

I also think so.

Re: RF 100-500mm F4.5-7.1 L IS USM and RF extenders

I have a strong suspicion it won’t be all of those things.  Especially, if it’s f5.6 at 400mm it’s almost guaranteed to be bigger and heavier than the 100-400 mk2 and it will certainly be more expensive.  I think building up the expectations that this lens will be f/5.6 is just setting yourself up for disappointment.  To me it looks like Canon is leveraging the extra light to the AF sensors that comes with removing the mirror to try to make the lenses smaller and lighter and they are expecting us to just use higher ISO to make up the shutter speed difference.  It’s not the trade I would have chosen but it looks like that’s what you’re gonna get with Canon.

Re: This is ...

We will see.  I’m guessing $1500 after several years on the market.  Think about it, the glass is going to be the same size as the 100-400 mk2 so why would it cost any less?

Yes I think it will be better on the new lens, the 100-400 mk2 with 1.4x TC isn’t exactly a high bar in terms of AF speed.

$2299

Agreed. I would not expect it to be less than $2299. It's worth more than the EF100-400/LII which lists for $2199 (yes, I know a lot of people will say it is on sale for $1799 at the moment; that doesnt change the expected price). It will be better than the EF100-400LII in every way.

How about the long game?

The 100-500 seems like another canon action to think out side the box.

RF 28-70
RF 15-35
RF 70-200
All of those lenses are not quite what we are used to, and same goes for this 100-500. It is slower than we want/expect, yes, but it is going to be smaller and lighter than the 200-600 from sony.

But how about the long game? I think it is reasonable for canon to actually come out with another RF lens in the range of 200-600 for example. For those we shoot mostly in the day, and want a light and smaller lens, then this would fit the bill. But I wouldn't exactly call it a sports camera. I see it more for wildlife, birding, and landscape, but not sports as in basketball, stadium sports, Olympics where lighting can be dim or challenging.

I think many people keep looking at the lenses canon puts out one at a time. Rather than realize that the lens line up is not fleshed out. It is becoming quite obvious (to me at least) that canon has put a lot of thought into the line up, and they are moving at an extremely fast pace. Remember... R5, olympic year... you guys seriously thing there won't be olympic worthy lenses to come out??

I see this 100-500 as a great option for someone like me, or for people who want something like an 100-500 and own the RP. I would like to get into more wildlife casually. I would like to take a lens like this on trips. Many of the super zoom are quite large, heavy, and expensive.

Cause lets face it, it would be more expensive if it where f3.5 to f6.3 and bigger too.

So... 7 lenses this year. What do you guys think they will be? Maybe some f4 zooms, maybe some f1.8 primes. But I wouldn't be surprised if a good olympic worthy prime and maybe zoom is in the mix.

Re: $2299

Well we already know for sure it won’t be better in every way because Canon has officially said it’s f/7.1 at the long end.

Re: How about the long game?

that’s sort of like saying it’s thinking outside the box to say that a 500mm f/5.6 is going to be smaller than a 600mm f/4.

the long end is 500 not 400

if at 400 it is f5.6, then I would expect it to be better in most every way

otherwise, how are they going to charge as much as the 100-400 II for a new RF L lens

Re: $2299

They charge that much because that’s the price point for that segment of the market (slow telephoto zoom).

well, I have a 55-250 stm that cost me $170 that is 400 mm fov that is pretty terrific on my t7i for what it is - it is actually sharper at 250 mm than my 70-200 f2.8 L with 1.4 II ext at long end - therefore I sold the TC

Re: $2299

For what it’s worth, the 100-400 with 1.4x TC is extremely sharp.  It’s just the AF takes a hit and f/8’s fairly limiting.

my 55-250 was definitely sharp enough but it definitely wasn’t any sharper than my 70-200 IS a/1.4x TC.  I ended up dumping both lenses.

I have the 55-250 stm, it's good, versatile and compact, also very sharp for this cheap zoom category,  but I find my 70-200mm IS II with TC is sharper,  also  the 70-200mm is so sharp that I can crop 200mm at 250mm "equivalent" and still get sharper images than the 550-250mm at real 250mm, so the TC can make a difference if the glass attached is very good, but the size and weight difference is so big that is good to have both.

slightly for the L II with TC

I have the L

also FF vs 7dII crop IQ becomes factor
