Hi fellow EOS R users!
Before I order the quite expensive RF to EF filter-adapter, I'd need to know whether it does actually protect the sensor from dust.
I'm only episodically interested in the use of filters, rather looking for a way to "seal" the body during lens changes in dusty environments (EF lenses, of course).
I would most of the time use this adapter with the neutral filter.
Thanks for your answers!

From my use of it the past months: there's a lot less dust on my sensor, but still a few new spots have appeared. It's hard to do an objective comparison, but I would say it's 90% less dust, if not better. This is on an RP, so I don't get that fancy shutter closing the R has.

Apart from the dust, having a polarizer that won't reflect like crazy with macro flashes is so nice that I'm hesitant to replace EF lenses with the RF counterpart when they appear.

He was dropped by the Canon program. That's the explanation on the Canon bashing. And Sony is trying to buy every youtuber they can buy. Everything seems pretty normal in the gear/photography world.

I hope the 150mm f/2,8 OS comes with refreshed design and a Art badge....

Understood. I missed the point yes. If the shot was taken from a far and then cropped to 85mm angle of view then you are correct.

neuroanatomist said:
Sorry, you totally miss the point. The idea is to take the headshot with the 50mm lens from the same distance one would normally shoot a headshot with an 85mm lens, then crop to the FoV of an 85mm lens. Same distance = same perspective = same distortion (or lack thereof, in this case). Perspective (and any distortion associated with it) is determined only by distance to subject. If you don’t understand that, please (re)read my reply to @Dantana above (expand my self-quoted section), the proof is in the beer (bottles).

Beautiful pictures. Well done.

Thanks for the compliment.

Complaints are not facts. Forum and Internet experts will complain about anything.

I don't complain much about Canon, but the 7d2 was not my favorite. I found the autofocus to be iffy and the sensor to be noisy. I sent it to Canon twice and sold it with no regrets. I actually regretted getting rid of my 50d. I am odd because it seems no one liked it.

Actually the reco mended ISO 8601 date format is yyyy-MM-dd.

It doesn’t recommend it, it mandates it (where full representation is necessary). Note the hyphens are optional. YYYYMMDD is sufficient to satisfy the SHALL statement.

Another piece of the puzzle may be that it is getting harder and harder to convince people to upgrade because what they already have is so good.

Try telling that to anyone on these forums

No they will not. Because it is new, Canon will have IP protection on the communication protocols used in mount for many years to come. People can use the EF mount now because it is an old mount dating back to 1987 and any patents protecting it have long since expired.

It is possible that Canon might allow some third party lens manufacturers to produce lenses for the RF cameras in order to create an ecosystem quickly for the cameras, but IMO it is highly unlikely that they will do the reverse. That is the great thing about a new mount system - you get to decide who uses it, how and when. It belongs to you and no one else.

The only RF mounts you are likely to see are dumb mounts (the bayonet but no electronic signals) or something produced in backroom factories without consent in places with weak IP protection, such as China.

I'm not sure why Canon would not license the new RF mount to other camera body manufacturers.......it would help Canon sell MORE lenses, and help spread RF mount as a standard, much like EF is sort of a standard today.

Seems to make business sense to allow others to use the mount, so that Canon can sell more lenses than just what their camera users need.

It's way too skinny, like the freebie straps tossed in with a new camera. I prefer a really wide one to distribute weight over the shoulder. Notice in the demo video no one has a large lens.

I was just thinking, if this hit you, sure you're gonna likely lose your images....reformat that card.

And as far as the camera, I would think refreshing the firmware would get it working again....?

yeah, good luck with that. Toss the card. Do not take any chances. As far as your camera goes, I'd think anyone going to the trouble of hijacking your camera's operating system probably has disable all the menus, except theirs demanding the ransom and the ability to enter a code to free your system (then good idea to reload the firmware).

Did anyone else notice that recently the Windows 10 login screen photos are now showing credit to the photographers? There was some grumbling that Microsoft was paying for stock images unbeknownst to the photographers but also that the images were completely uncredited. Now it shows the photographer's name and the agency from which the image was licensed. So that's cool now they can get recognized personally.

I do not remember seeing patents about RF protocol.

There was one about boosting communication speed based on the lens attached.

Emulating an EF lens should be still fine, though.

I don't care what they were. There was a time when a consumer 28-80 lens was a "premium upgrade" to a kit 35-80. But the times have changed, and today a "standard" zoom without a 24mm equivalent in its zoom range cannot be called "an ideal lens".

I totally agree with that!
I got used to having a 24 equivalent on my hs10 9 years ago and when I bought my Apsc camera 18mm wasn't wide enough sometimes.

Now I use a 17-50 2.8 which is ok on the wide end when you get used to it.

The EFs 15-85 is a great lens, but a new version is long overdue.

Or at least the same lens at a better price.

Oh good idea on the books. Do you have any in particular you could recommend?

The Negative and The Print are the two most relevant volumes to this discussion. Other people have done updates on his Zone System for the digital age, with varying results.

I like the one on the right more, as I favor punchy blacks.

But if you get rid of your adult children and pack in the grandchildren (newer and smaller format and probably also Mirrorless) you can fit in more!

Nuh.. just use any of these instead. let kiddies and dogs travel in style, music volume to the max, soft drinks and in front of a large screen TV. While you, as a driver, enjoying the road in your very own way. And in moderation

The new Viltrox mirrorless lenses - Photo Rumors

Some additional pictures of the new Viltrox 23mm f/1.4, 33mm f/1.4 and 56mm f/1.4 mirrorless lenses with AF for Sony E, Canon M and Fuji X mounts taken from Chinese social media (Viltrox lenses are sold at Amazon): Viltrox 23mm f/1.4 Aperture Range: 1.4 – 16 9 Aperture Blades 10 Groups, 11...

the rumor says they're not only for fuji x and sony e but also for canon m
sigma will have some competition

powerful computers doing ray tracing

Probably the available computing power - even for rent - is lowering the bar to enter the lens market. Then there are the manufacturing skills, true.

The minimum diameter for a front element for a 70-135 f/1.8 would be 75mm, at f/2 would be 67.5mm, and for 70-150mm would be 83.3mm for f/1.8 and 75mm for f/2.

Would be around 105mm in Sigma Art money

The Sigma 50-100/1.8 Art (APS-C) thread filter
Size : 82mm

Sigma 105mm/1.4 Art (Monstrosity) - 105mm

I have got one up for sale for months and not a single punter. they all run away as soon as the lens being taken out of the box. It is a scary large 105mm prime.

I just encountered the same problem. After some research, it seems it has nothing to do with the batteries or lenses. Turns out it has to do with the Auto Sensor leaning function when you turn on the camera. If that has a problem you can get the error. You can interrupt the error by opening the CF Card door and closing it. Then disable the auto clean function in the menu.
The camera will work fine, but you'll need to get it services to fix the sensorclean function, I believe.

Thank you all. Lesson learnt: Be humble!

The 24-240 is a little bigger than the RF 24-105/4L. Personally, I think that’s about the right size lens for the R, and the RP might feel a little small relative to the size/weight (perhaps the little grip extender would help).

I used to take my SL2 with 15-85mm everywhere. I know there will be no FF combo that size with that focal range, but I'd still like something small enough to carry without a huge camera bag. The grip on my R almost doubles its size or it seems like it.
