I love my 200mm 1.8. When you need a high speed tele, not much else will do.

I actually know of one being sold (a 200mm f/2) for $3,750 on an astronomy website

Which one? Never thought about checking any astronomy websites for Canon glasses Thanks

The 1200mm f/5.6 had a built in 1.4x when it was an FD lens

The new Sigma seems to be somewhat of a speciality lens, even among 14mm lenses. I would think that Canon has its sights on a more rounded design. Going for 2.8 rather than 1.8 has a number of advantages as far as optics, size, weight, and possibly even as far as price is concerned. I don’t expect an “L” lens to ever compete on price, and I don’t want it to if it means a compromise somewhere.

If you’re an amateur, price means a lot, but if you’re a real working Pro, it means less.

In terms of the full frame coverage that Fat Fish was talking about, I just can't imagine that, even without going to ultrawides, 16-35, is not wide enough, even with 1.7 crop. I mean, that's 27mm full frame -- who needs to shoot video wider than that?

It is not necessarily just about how wide you can go, it is more to do with using the same lenses and getting the same aesthetic for video. Neither the 16-35mm f/4 with IS or the f/2.8 is ideal for a photo/video lens (a 24-105mm f/4 IS would be a lot more useful).

FF photo/video was the thing what got many people into buying the 5D Mark II in the first place (and 1080p was good at that time, it is still good today for some, but there are other features that are lacking - deliberately limited - besides a touch LCD and DPAF).
Yes, the Sigma 18-35/1.8 works ok (still no IS, rolling shutter can be noticeable), but do you really need to buy extra lenses just to use that 4k? While there is also a crop on the 1DX II, it is much more manageable with less rolling shutter as well. But I'm not sure how good is it as a run-and-gun camera, it is just very big, heavy and also quite expensive.

While the Sony offers much more features that are useful, the color, ergonomics, much wider range of affordable lens options and AF still makes Canon very strong even with all these limitations, and it will be interesting to see which direction they will go with mirrorless: even more limitations or cutting back on those.

What does BR stand for?

I'm not sure if the person above me is being serious, but:

BR = blue spectrum refractive

Good stuff.

I quite like Yamaki's interviews.

My experience is similar to yours and I only have a very few shots where the lens did not focus accurately. I shot bursts of 25-30 frames using AI Servo and it focussed quickly and accurately almost every time. In my test the subject was running towards the camera, and the only shots that are out of focus are right at the start of the sequence when my subject is furthest away. I just watched Dustin's video and his experience is the same - there are a few out of focus shots when the runner is far away but as the runner approaches the camera every shot is focussed correctly.

My copy is also superb in consistency and accuracy, although i don't use it for action at all.

I think the autofocus is very fast, certainly snappy enough to keep me happy, though not among the fastest of Canon lenses.

Does this firmware upgrade remove the mirror? I keep reading on all the web forums about how terrible those things are. Why they are so bad never seems to get explained but if all those clever people on the web say they are bad I guess it must be true.

There has been a lot of talk about how bad mirrors are when used in cameras, but it only actually becomes a problem if you regularly take photographs of vampires.

This is a horrible setting (at least, for me).

If you set it to Viewfinder, it's always ONLY on viewfinder, and there is never anything on the back screen, which means you can't check your exposure setting unless you look into the viewfinder (since there's no top LCD).

If you set it on Monitor, the viewfinder NEVER works. And who wants that?

What I really want is Viewfinder + Monitor so that you can force both to be powered at the same time, and never powered off unless it goes into sleep. It is ok for the monitor to have the basic exposure settings only. Frankly, I don't want most of the do-dads on the back display that Sony shows, like the electronic level and all that. Just mode (M/A/S/P,C1/etc.), aperture, shutter, ISO, drive mode, focus area, flash/hss, EV+/-, and shots left.

Also, some high performance, battery-eating, viewfinder mode where it never shuts off unless I turn the camera off, because in wildlife photography, the fraction of a second between black viewfinder and seeing something is precious time lost. I can always feed the camera another battery.

Click to expand...

Yah I don’t use it, but if it’s mapped somewhere I could see it being useful. When I used an A7Rii I mapped C4 to turn everything off. With the bigger battery it hasn’t been a problem. My only issue is that sometimes when I go from a bring area into shade it goes to the EVF, so I’m assuming it’s a brightness sensor not proximity.

Unless the lens is as light as the EF-M 18-150 mm lens (300g), I have little interest in super zooms. ;D

It really is a fantastic facility.

The reason being that monthly performance is strongly affected by what happens to have been released just prior to that, both this year and the previous year. In the case of these February numbers, DSLR numbers have been kicked up by the recent release and backlog of the D850.

Click to expand...

The average price per unit of DSLRs dropped precipitously, from just under 60,000 yen to about 45,000 yen, or about $560 to $420. That doesn't jive with your hypothesis of the month's DSLR numbers being boosted by earth-shattering sales of a $3,000 DSLR.

The CN analysis of shipments of entry level units makes much more sense.

A more plausible analysis would be the opposite - that the Nikon D850, while indisputably popular as a full frame flagship, makes up only a very small percentage of total DSLR sales.

"stand corrected"

These words seem disproportionate when considering the relevance of your argument I have to say.

To make the real conflict more obvious:

Just a personal observation, but I think it's ironic that Canon is always receiving environmental awards and no one in the environmental lobby ever notices that Canon's printer rebate policy is wasting huge amounts of energy and resources manufacturing printers, most of which are destined to go to landfills.

To explain: the standard procedure these days is:

• Buy the camera/lens/printer bundle
• Send in the rebate
• Pull the ink and printer head out of the box
• Sell the ink and printer head on eBay
• Throw away the printer
• Start all over again with the next rebate cycle

Yes, as an option -- but I don't think it will happen.

I did not see any hands on, just a Canon rep waving it around and talking it up.

I actually might be interested if it would work on my phone with the case on. Wi-fi or another type of wireless connection might be better yet

Thank you for sharing this information.

A firmware update for the 5D mark IV is now available for download, and has been for a while at the Canon UK site if the date in the screenshot is correct.

Sadly no added functionality à la Fujifilm....

not necessarily. Only sometimes. At best.

and if this was a commercial product, the site that I work at would buy several dozen....

Looks like there is a real problem with the 24-70 @ 50 mm, i just compared with my cheap 50mm, here are the results. Pretty similar in the center but in the corners the 100E lens looks amazing compared with the 24-70, totally disappointing.

And nobody ever asked in the thread if toddlers were present in the house when the mysterious water damage occurred. My 20 month old is on a mission to remove knobs from any electronics which still have them. Haven't caught him in the act once, so it might, in fact, be his slightly older sister--but she blames him.

They are getting better at doing other mischief and then hiding evidence to delay discovery.

Then there might be the drunken guest at a wedding who...Use your imagination. There are countless ways for "impossible" water damage to happen.

And some of the backpacks the past few years have been nearly water tight, so if a camera is in a damp bag in a car in hot sunlight, wouldn't considerable dampness be steamed into even a "sealed" camera, or through the lens mount?

I’m looking for one good 20mm too with AF and light weight (lighter than my 16-35mm f/4). Let us know your final decision. Thanks.
