I wish they had chosen a Sony MILC (poor battery life)...

Last friday I shot around 1700 frames with my gripped R5 (fw 1.5.2) & RF 50mm 1.2L...
I had 1 hiccup in the middle of the birthday party: no blackout (that happened rarely in the past), but the camera froze once: it became unresponsive and the EVF was frozen. Turning it off and on fixed that, no need to remove the battery.

I really like your pictures, Maximilian. Especially the first one.

Can I use the new Canon EOS R5C without battery and power it with the Ronin RS2 when the R5C is on the Ronin ?

I had some issues this evening trying to focus on a strongly backlit owl that was strongly in the shadows. Might be the limitation of the camera by overall the image was a bit soft. Might also have been a bit of motion blur since I was handholding a large lens.

Why couldn't they patent the RF lens flange and skip the camera side mount instead? (Assuming they can only patent one)

They could have indeed patented a novel lens mount, and it would have allowed anyone to make cameras with a mount that fits the lens.

Which is what pays the bills, and is reality... I prefer to operate in reality. I don't care what it looks like pixel peeping at 100% on my display. The only people who will ever see that is me.

Specific sky targets such as galaxies and nebulae sit around 200-450mm.

Well it actually depends entirely on which target. Some close by galaxies like Andromeda will fill the frame at those lengths. Others would be better at 1500, others would be better at 3000, etc.

Unfortunately as far as I know the original version of cameras is not available anywhere. I wonder if service centers can help though...

This means an F2.0 RF lens trio is still a posibility?
I think 2(!) years ago there hase been a rumor about it.

There is no correlation whatsoever.
These lenses are huge, expensive, and not mirrorless lenses.
I also doubt these T2.4 lenses are f/2.

I have the lens too and I’m quite happy for my use cases.


For selfie I don’t care about corner sharpness, but all other aberrations are perfectly controlled.


For astro I won’t use the lens corrections but light frames to deal with vignetting .. no one cares about straight lines for Milky Way photography so I actually get sharpness and contrast where I need it. Coma is fairly okay, worst case I have to stop it down to f4 .. still better then the EF 16-35mm f4L for Milky Way I reckon, it had more aberrations traded for better corner sharpness.


Big plus for the smooth bokeh and close focusing distance!

most annoying is actually the lack of weather proofing, despite its small size I’d like to leave it out for Astro for a couple of hours and don’t have to take it down during a small drizzle.

Where do you base that? I strongly doubt it! Not only from my 16-35 4L IS experience in landscape and astro but also from lenstip,com full review. Sorry but I do not accept your statement. You can like the RF16 all you want or you can pursuade yourself - I do not care - but what you say about 16-35 does not hold.

Red does support rf glass. Mkbhd carries the r5 as his camera because it can use the same lenses as his red v-raptor. Red's new cameras use rf glass

I have this lens too and I like it. Yes the AF isn't that fast, but I've also used the 85 1.2 and I didn't find the AF to be much faster on that lens either. Yeah it has the USM which moves faster but it also has a lot more big heavy glass to move at 1.2, which ends up making it kind of a wash imo. But this lens is much cheaper, great IS, and has the Macro/close focusing which are actually improvements over the 1.2 for a lot of people. I wouldn't choose either of the Canon 85s for an application where AF speed was the main requirement.

Nice necrothreading, but yes – the active AF point is recorded in the EXIF. If you're using BBF and not actually pressing the button, there is no active AF point.

May want to give Flashpoint/Godox a look (pretty good bang for the buck). Adorama sells the Godox rebranded as Flashpoint. I have a few strobes/speedlights from FP and I like them.

Mine is left in airplane mode and doesn't drain.

MIne kept draining when not being used for a few days and after enabling airplane mode it stopped draining. I hadn't expected leaving bluetooth enabled would cause such a drain, it doesn't do that on my M6II.

For my 5d3 / 5d4 I always used Sandisc cards...
When I got the R5 I switched to Sony Tough, and then when I got a second R5 I picked up an Angelbird card.
The Angelbird card had twice the capacity (512 vs 256,) for close to half the price!!

The Sony is NOT worth the extra money - It gave me a little trouble, but the Angelbird
has been great. Highly recommend!

Angel bird is a great company, with great support.
They may not be as well known as some companies,
but it is easy to see they care about their products -
I have already ordered another 2 Angelbird CFExpress Cards,
and an Angelbird reader (I picked up a Sandisc reader with the first Sony Card)

Disgraceful in an 'L' lens. Klaus at OpticalLimits always comments on the 'centring' of lenses he tests, and my impression is that price and 'pro status' seems to count for not much at all. All makers too.

Roger of lensrentals has had several blogs about this. These two sum up what he has found.

Just wondering if there would be anyone on the board interested in a Canon EF 800mm f/4L IS USM lens?

Granted, it would probably cost close to $18k, but since such lenses are often mounted on tripods would the weight actually be a factor?

I think this would be an awesome lens.

Click to expand...

It would need to be 4.5kg or lighter and $17k or cheaper. Was looking for lens thread for the 800mm so I just end up replying to this

Canon may have the conceit that it is very close to the pro market with CPS, so it doesn't need to market to that social media channel.

The Facebooks, etc. will be more relevant to lower-end equipment, which also lends itself better to a "media spend" sort of marketing strategy, employing volume economies of messaging scale. But, having worked for Sony's ad agency back in the day, it's often the case that we interpret these decisions as rational logic, when in fact they come out of the weird "decision-from-Japan" black box.

For the purposes of generating some story ideas, I once looked at all the social media profiles of the Canon US and Nikon US employees. You don't get the sense that the brunt of them have much to do with cameras or the photography communities around them. Their job roles tend to be more about distribution and channel sales. I doubt many of them know the specialty forums.

Hi all
Thank you for your comments. Yes, I am using The Digital Picture always as first. I was interested if this coating really do this job as they mention. Thank you

The full frame zoom market is now pretty fleshed out. I like the idea of faster, so we are talking T2 or faster. My guess is a cinema version of the 28-70 f2? I adore that lens. Might be a nice way to be distinct. The primestas have the best mid range throw with the 28-100. But Arri, Leica, Cooke, angx, zeiss and Fuji all have great options now. It’s a tough market. Around 40k you have the Fuji which is popular, and is a solid choice.
