It's the hot shoe adaptor that you use with a smartphone.What exactly is the AD-E1 smartphone adapter?
Hmmm. The RF600 is the same as the EF600 with a permanent adapter. Under-whelming.If they did manage to keep a RF 500 mm f4 under wraps that would be very impressive. I don't remember a lot of rumors about the 2018 EF 400 mm and 600 mm updates prior to their formal announcement, but I might be mistaken.
I think the person you’re responding too is referring to 2018 when the original EF v2 versions were released and the lack of rumors about it at that time. I assume the announcement just came from Canon with little build up?Hmmm. The RF600 is the same as the EF600 with a permanent adapter. Under-whelming.
If it is like past announcements, the first reviews probably won't tell us much -- just run through the features and a few first impressions. It will be a couple weeks, I think, before we get any in-depth reviews.I do not care so much about the announcement, which probably will not give us a lot of news, but much more about all the reviews that are already completed , but can't be published before the announcement. They will likely go online within less than one hour after the announcement. We will proboably see reviews by Jared, Kai, Gordon, the Northrups, Peter, DPReview and others all tomorrow. They could publish the reviews today, but then they would have to pay a lot of money to Canon.
"The EOS R3 is is The first EOS to feature an entirely new stacked BSI CMOS sensor" So likely its performance is different - better We all hope.Unless there’s been some type of major breakthrough in high ISO performance (or one is imminent or likely within the next couple of generations) I’m honestly meh towards this sudden influx of ultra-slow zoom lenses that the MILC era seems to have enabled. F5.6 is already stretching it thin as it is…JMO. Perhaps there is something else on the horizon that will help all this make more sense…there has to be.
Curious about that 16mm though…
I have read somewhere that the buffer is infinite and reliant only on the capacity of the card.For me there are still a lot I do not know about the R3, which I really hope the following info is released in the formal announcement or covered by reviewers of the camera:
1) What is the buffer depth and clearing rate?
2) Can the electronic shutter be used at speeds slower than 30 fps?
3) What is the flash sync speed with electronic shutter?
4) How good is the high ISO noise?
5) Are there cross-type AF sensors (I doubt it, but would be a nice surprise)?
6) Does the eye AF work well with normal eye glasses?
Hopefully, there are still some surprises!!
It looks like there is some conflicting information from different sources:
If you actually new anything about lens design telephoto lenses have little to no effect of barrel distance of rear element. The design of the 600III is already redesigned to have most of the internal elements shifted rearward to lighten the lens dramatically (less elements).The newest, most advanced, best supertelephoto lens ever just isn’t new enough? Can you share what improvements you would suggest?
A supertelephoto designed from the ground-up for RF could have numerous improvements, such as being designed to take advantage of the 11 RF mount pins, which can transmit additional information to the body and potentially improve focus speed/accuracy.The newest, most advanced, best supertelephoto lens ever just isn’t new enough? Can you share what improvements you would suggest?
