Link: Birdies with the 90D + 600mm/4L + 1.4x

Hi Alan
So I am not a scientist :) and I don't have enough hands to operate a stopwatch for the exercise.

About the cards, with a Sandisk Extreme Pro 300 Mb/sec SDXC II card of 32GB capacity, at shutter speed 1/1250 at f4.0, iso from 400-640, with Release and Speed priority AF enabled, I can get 29 RAW shots before the camera stops. With that card, it seems that within one second or perhaps one and a half seconds I am able to start shooting again, not the full 29 but at least some bursts of 4 or 5 frames.

With the Sandisk Extreme Pro 95 Mb/sec SDXC I card of 64GB capacity, at shutter speed 1/1250 at f4.0, iso 400-640, same camera settings for AF as above, I can get 28 or 29 RAW shots before the camera stops. With this slower card, it seems that I can start to shoot again within about 1.5 seconds roughly, but its two or three shot bursts before it stops again. The main benefits with the SDXC II cardseem to be in if you fill the buffer then delay before you can start to shoot again is significantly less.

The third test I did was to use the SDXC II card (300 Mb/sec) again, but with the camera set as above except image quality was changed to C-RAW, and the 90D took 113 shots before filling the buffer. So a viable option for action sequences...:)
Cheers

My Sandisk Extreme Pro 300 Mb/s UHS-II arrived yesterday and I tried it versus a new Sandisk Extreme Pro 170 Mb/s UHS-I card. Identical performance as far as I can see.

An RF super telephoto zoom on the way, likely in late 2020 [CR1]

Thanks for taking the time to look up all those numbers, but you needn't have bothered. All of those lenses go to 600mm. The focal length at which they become f/6.3 is irrelevant, they are f/6.3 at 600mm.

Yeah, and lens makers have never, ever, not once rounded the rated f-number at the maximum focal length down from what it actually is, have they? :rolleyes:

Or used the two separate data fields in the Canon EF system (apparently placed there way back in 1987 to allow for tilt/shift lenses with manual aperture rings to report both their maximum and current aperture separately) to tell the camera it is an f/5.6 lens set to f/6.3 when the actual maximum entrance pupil at maximum focal length is f/6.3-f/7. :eek: (cough - Tamron - cough, cough - Sigma - cough - Kenko - cough, cough...)

Canon officially announces the IVY REC clippable outdoor camera

I guess Canon knows their market over there, but wow...I still keep asking myself WTF would you do with these things?

C
Non fish eye lens perfect for body cam, clip it on to a backpack and use it for recording activities like trekking, biking, etc... like I mentioned before this is where Nikon Keymission 80 was targetted but failed. Canon Ivy being cheaper and much easier to use will be selling with same action cam crowd who dont want a fish eye camera.

The end of an era? Review site Imaging Resource nearing its end

While I certainly enjoy an occasional video 'review'. I personally prefer reading reviews. I find the written word makes me think more. Whereas a video just makes me think about the presenter, what's in field of view, etc. - so distracted to an extent from the actual content. So sometimes it's just another form of entertainment - especially when I'm watching Jared Polin - Froknowsphoto.

However, a few individuals that I find myself watching with some regularity, because of their content and how they present are: Matt Granger, Dustin Abbott, and Tony (& Chelsea) Northrup. These ones present in a pretty no-nonsense way and they make me think. With Dustin I like that he still does written reviews as that is what I prefer, he and Bryan Carnathan (thedigitalpicture.com).

I agree with your assessment concerning subscription models.

I wish Northrup wouldn't do a "cut" after just about every sentence, speaking of (unpleasant) video distractions. Of course most here would maintain I shouldn't be watching him in any case (and I certainly try less often than I used to).

Canon is gearing up for a big 2020 [CR2]

@Kit. As I mentioned earlier, my chat with the rep was purely about my use case as a hybrid shooter. The rep agreed with me that the Nikon Z range and Sonys are currently more capable for video/photo hybrid shooting than the EOS-R (crop factor, Nikon pro-res update coming etc. etc.). He advised my to hold off buying a 1DX MK II now (even though price is coming down) and waiting for March next year. He said he is also personally holding off until then. He probably was trying to get me to wait so I'll be tempted by the much more expensive mirrorless option next year, not sure I'll do that but undecided myself! Useful advice anyway, not sure it was that controversial.

@slclick I am extremely hot and hand out sexual favours for details of mirrorless camera product lines :).

EOS 90D - Hands on review

They should make new tele lens ,worthy for new 32mpix sensor.
EF-S 150mm f4L sharpest canon lens never made and weight like 200g
around 135mm lenses seems to be sharpest on sony and zeiss.
I'd like a very light 300mm f/4 to replace the antique one. It won't be any heavier to have it FF. The Nikon PF one is really good.

We’ve received the pricing for the new RF lenses

I can't argue for most of those lenses, so I'll have to leave it at "time will tell".



Both Canon EF 75-300mm are cheaper than the EF-S 55-250mm IS non-STM (at least at the moment @ B&H). This seems to me like dump prices (= Canon trying to get rid of existing stock), rather than the lenses being manufactured & sold at a profit. Canon not having IBIS, and the low end market shrinking, I don't see IS-less teles selling that well.

Maybe, but it seems to me that they're still moving more units of the EF 75-300mm f/4-5.6 III (non-USM), when the units sold in kits are included in the totals, than the rest of your list combined. They've been practically giving them away for at least a decade.

I think that most folks who buy an entry level Rebel with a two lens kit have no idea what IBIS is. YMMV.
