A circular polarizer is a stack of a linear polarizer with a quarter-wave plate behind it, the latter circularizes the linearly-polarized light, which eliminates the problem of linearly-polarized light interacting with a beam splitter where the angle of polarization will affect how much light is passed into each resulting output (on and off-sensor phase AF, but also the dedicated metering sensor in a DSLR, are behind beam splitters).

Thanks.

I have one, works awesome except for the fact i have an old camera so full auto doesn't work. Upgrading soon!

Turns out to be the confusion and drama of teen hormones.

Be prepared?! Haha didn’t realize we were in Lion King haha. Seriously this makes me feel much better about my video editing skills and that maybe one day I could work for a big corporation and blow them away with my supah skillz!

Haha. Really bad video, i started laughing so much when i saw it. Well the wait isn't that much since in Japan is 0330.

The 77D is an excellent size and weight, so I'm happy that the R is similar. But for me the 77D grip is not comfortable for extended use. I find it painful in the wrist to use it with a flash over a longer time, much more so than a 70D/80D/6D/5D. The 77D really needs an add-on grip to be comfortable, and yet Canon doesn't offer one (some 3rd parties do). Hopefully the new R will have a better grip than the 77D.

The 35mm f/1.8 looks promising. Wonder how much different it will be in IQ to the Nikon 35mm. The Nikon is way to big for a 35mm I think....

The IQ on the Nikon 35 looks outstanding-- I saw some test shots on a Z7 that were jaw-dropping.

A huge lens, just as expected, but really tempting to try this little monster. Seems that the whole package will come without image stabilization since the EOS R has no IBIS according to the latest spec list rumored (maybe later models will offer some IBIS). I personally don't mind much, because this lens will be so heavy that you can rely on its Passive Inertia Stabilization (PIS). Plus, I don't sheik my booty so much when I shoot

I have to wonder how the R line of FF cameras will impact the existent M line, especially the market for used ones. Think I will follow M50 body and lenses on Ebay for the next several days and see if any kind of pattern develops on new listings. Of course, we still don't know when the new cameras will start shipping yet. That may be the important influence here.

This is sad. Why to even bother with Mk. III release?

I wonder, companies like Sigma and Tamron can take their single optical formula and launch it with different mount for 3-4 manufacturers. Could Canon just delay this wonderful release and instead of Mk. III announce it as 70-200 with RF mount by keeping the same optical formula?

It looks like the Canon R is going to be a nice starting point, it seems to have some specs that are better than my 5DMKIV and some that are better, time will tell I suppose!

I've used the Canon 10-18mm EF-S and it is a very nice lens for a crop camera.

definitely not possible the c200 won't accept settings from a c100.
you probably can make custom profiles on the c200 but for raw it's a non issue and for xf-avc i use wdr/productioncamera color profile/matrix

compared to the M5 and 70d the xc10 will be a joy to use and the image quality will be good.
If you can get it cheap enough it's a nobrainer.
However a c100 upscaled to 4k will look better or just stay at 1080p .

Tonight I did a comparison between 8 different wide angle lenses. The only adjustment I made was for white balance and size. There are no distortion corrections. All lenses were focused manually, so we can expect some margin of error there. The unexpected disappointment was the Vivitar 28mm f/2.5 and it's flair. All the Takumars had a hood. Nothing else had a hood except the two modern Canon L lenses. For colors? They all looked the same to me. Some had some CA. As expected, my Canon L glass gave the best results... but it should. There was a little flair with the Canon EF 24-70mm f/2.8L II at 28mm, but that is due to the way the light on the wall is right at the edge of the frame. The take away from this is that most all lenses are sharp in the center at f/8. Not a surprise. Also, without interference from bright sunlight, they all do well color and flair wise. I would imagine a hood on the Vivitar would take care of the problem. Keep in mind that these are 30 second exposures at night, so don't get too excited about the vintage lens results looking so good against the modern Canon lenses. Daylight reveals much higher variation. Much higher. I will conduct the same test in harsh sunlight in a few days. I predict drastically different results. I'll make sure every lens is has a hood for that test. If you are not using hoods, I recommend that you do. Full resolution photos are found here: https://www.flickr.com/photos/135571631@N08/?

Thats not the camera.. Notice the Mode Dial on it..
Also that looks like Ken Wheeler...

No Tatts...

Canon does not put IBIS in their bodies, I've never missed it. Lenses long enough to need stabilization get IS, which works better.

I was thinking about selling my EF-S lenses ahead of the release of the R. But if I understand it correctly the EF-S lenses will work on the R body? Thinking of keeping some of them instead if that's the case..

Click to expand...

According to the leaked specification, they will work on the R body (and may even be a good choice for shooting 4K video - if it is 1.75x cropped, as currently assumed by the collective opinion on this forum).

Yes, but not as many as we should be getting! There's a 35mm f1.4 lens coming out on 5th September, but still not enough native lenses! E.G. Nothing over 300mm yet.

An adapter with control ring sounds promising! It would be nice to assign ISO to it...

As #2 Nikon can afford to be bold with their new products. Look at the Z7, it competes with the D850. They are not afraid to have the Z7 steal business from the D850. Plus the Z7 will steal business from Canon.

Canon on the other hand protects their products from each. They provide clear points of difference between each body. I wonder what they will do with the new ML? Will it compete (and exceed) the 5D M4 or 5DSR? Or will they cripple the camera is some critical way.

I think has made some great products but currently they are too conservative. They seem afraid that a new product will eat an existing products lunch. Well if theIr ML products are too cripple to product the 5D M4, 5DSR or 1Dx M2, they will fail. And to some extend Nikon will steal business from Canon.

So what is this. A plea to Canon, do your best. If the Z7 can shot 45.7MP at 9 FPS, then the next generation of 1DX or D6 should be able to shoot 30 MP at 12 FPS. Go for it.

This is just more market diversification. And I don't think it is any different than Canon, if they really are working on their own FF mirrorless. It's a new competitive market. Some people just plain and simply do not want a DSLR, and FF mirrorless has been dominated by Sony for a while. Canon, Nikon and even Panasonic it seems are now entering the FF mirrorless market. Even if it does "compete" with the D850, it will still bring in new business for Nikon, because there are many die-hard Nikon fans who want mirrorless FF, and would LOVE to have it from Nikon. It should be a growth opportunity for them more than anything.

There are some things I will only do with a DSLR. There are other things I really only care to do with mirrorless. Lot of times a DSLR is just way too bulky. Lot of times an EVF is so much more useful than an optical viewfinder (and it's odd for me to say that, as there was a time I wouldn't touch an EVF with a 10 foot pole...but they finally came of age, I guess. ). I would even offer that people could easily buy and own both Nikon D-series and Z-series cameras at the same time, as they are not necessarily mutually exclusive products. Same thing goes for Canon DSLRs and Mirrorless, or Sony DSLRs and Mirrorless.

I'd seen that as well.

But from the update yesterday on the story at I-R: I've bolded the quote. Hopefully there was no error in translation.

"(Update, 8/30/18, 1:16pm EDT: Contrary to the preceding and what's been reported by other outlets, this does not seem to be the case. We asked Nikon about low light AF limits, and received this reply: "AF is possible down to -4.3 EV with an f/1.8 lens, -4 EV with an f/2.0 lens and -2 EV with an f/4 lens." Also, there is no reduction in low light AF performance with F-mount lenses, apart from any due to maximum available aperture.)"

Interesting thanks for the reply.
I've always wanted a drone so this Mavic is of interest to me.

Click to expand...

as soon as i get the drone i'll show some dng... no one of the reviews compared this sensors mavic vs mavic 2 zoom

It's not a subset. Sony is #1 in the entire ILC market, in the world, most likely. I can only verify that Canon is #1 in Japan while Sony is #1 in North America and #1 in China. Both North America and China are larger markets than Japan by quite some margin. I don't think Nikon does anywhere near the volume of Sony or Canon anymore. Also, bear in mind when you say Sony has released a ton of bodies lately and Canon hasn't, that Sony releases new bodies every year and Canon doesn't. So this is "as intended" and will likely continue along the same trajectory.

Canon looks ready for a huge release with the 24-70/2.0 zoom and 50/1.2 being released immediately for RF mount mirrorless. I think perhaps Canon will have a comeback starting now, but it probably will be more at the expense of Nikon than of Sony. I don't think Nikon is likely to ever move back up from the #3 spot.

Since the pixel pitch is nearly identical, if one crops the 5Ds to the same size as the 7D Mark II, the results will be near identical as well. A FF sensor has no inherent advantages over an APS-C sensor if the images from both are enlarged by the same factor. The advantage of a FF vs. an APS-C sensor is all based on the lower enlargement ratio needed to get to the same display size.

Theoretically thats true practically I beg to differ

It could be CFExpress!
