Nice clean glasses on the needle ... :D You can see the dirt/scratches.

BrentSchumer: This inanely sharp...you can read the bar codes!

Yup, about the same results as from the new Leica M10, only way cheaper. Sigma should make lenses for Leica M.

LoScalzo: Considering that the camera used records at 24,000 frames-per-second, it seems that the frame rate does not provide enough temporal resolution to show the motion of light across a small tabletop.

The speed of light is 186,000 miles per second (slightly less through air, but the difference is trivial here). Therefore, during 1/24,000 of one second, light travels 7.75 miles.

A frame rate of 24,000 frames per second is nowhere near high enough to capture the frame-by-frame incremental motion of light across a tabletop. Think of a video camera capturing 120 FPS, recording a bullet fired across the imaged area. Perhaps one resulting frame would show a dark streak across the entire image (or a frozen bullet, if the shutter speed is high enough), but there is not enough temporal resolution (FPS) to represent incremental motion of the bullet across multiple frames.

The article seems to be missing some information about how a frame rate of 24,000 per second facilitates the end result.

3.8 nanoseconds is the shutter. That's 3.8 /10^9 seconds, which gives about one meter of temporal resolution.

On article DPReview TV: Leica M10-R review (104 comments in total)

Chris, I like your approach on the review, however I have my own personal views about some things which IMHO could be improved. First: the samples. Why not choose something more creative? You walk through the city in mid day sun, which shines an unpleasant harsh light and as a result those samples are mediocre to say the least. We're in the middle of the pandemics and nothing on that as a photography subject. Only flowers, architecture .. kind of boring. Second, Visoflex and LV: If I wanted electronic aids, I would have bought me any other product of the Leica line, but this is all about that RF. So 90% of the pics should have been composed through the RF, of which, I guess, you are not a huge fan. But anyway, the review is well executed.

Loreno Heer: I would much rather like to see a one-on-one comparison (eg. same lens and same picture taken) between this camera and the regular M10(-P). I did see some in focus pictures taken with the M10-R and they did look amazing in terms of colour and resolution. But I wonder if this is just some kind of placebo effect and an actual comparison between pictures taken between the two cameras (viewed at a reasonable size etc...) may be not as great as it seems. The M10 Monochrome on the other hand does have a real advantage (no bayer filter means higher iso and 3x higher "actual" resolution) over the M10...

Fuji 56mm f1.2; 90mm f2 are comparable. Fuji needs that 40+ MP sensor to show them off.

Foskito: The general consensus is IQ does not match the asking price.

Foskito, the Leica magic is all about pursuing the correct focus using the RF so that you can blame yourself and not the machine for the poor results. But, put it on a table and watch it for a minute, touch it, all its buttons and dials... It's a bit of a frustrating relationship, but once in a while you get the perfect photo out of it and you are happy until the next blunder comes...

The M10P would outperform the X100V if you get the focus right. I dunno if these were focussed using LV, the RF, or the Visoflex?? Off center frame focussing as we all know is veery difficult with the RF. You have to pan, guess the movement of the object, etc...You have to know your Leica well. Then, there's the parallax. This leaves you with little choice if you do not have your Visoflex with you, you have to do it like a P&S camera using the LV. And that steals the Leica moment. Leica isn't about IQ, the IQ is there but it's all about that RF. Having said all of the above, those samples are... let's put it - painful to watch, and I'm being moderate.

DeathArrow: Nice. Although hard to focus on a DSLR.

Fuji X-Pro and Leica M, both have an OVF (together with LV with a bit different implementation). But I like those 2 of the mirrorless bunch the most.

Entoman, exactly! I've used very fast lenses, both on DSLR's and mirrorless. On a DSLR, they are almost impossible to focus (even AF lenses). The annoying part is you switch to LiveView, you wait, then press the shutter and wait for the mirror to close. You are waisting precious moments. On a mirrorless focussing is great. And I mean almost every mirrorless with almost every lens. This is the reason (as well as bulk and weight) that I've given up on DSLR's. When you're on a photoshoot the model does not have time to waste and gets annoyed if you're using a DSLR with a MF lens. So, for me, a no go.

Thoughts: Surely there is a market for a compact full frame rangefinder (style) camera without paying your arms and legs? Olympus and Pentax wake up.

#peterwr, I recognize Leica M's as Leicas only. Pen F does not even have an OVF. Neither the Pen, nor Fuji's X-Pro is a true RF. Although X-Pro could be accepted as a kind of a RF, since it uses trigonometry when focussing in OVF mode and has a parallax.

Now, what's next? A true 0.95 crop equivalent for Fuji X? 35mm F0.63.

You can use it on a mirrorless with an adapter. On a DSLR it would be veeeery difficult to focus indeed ...

IMHO, around $1.5K, w/out a lens. Make it APS-C like the Fuji X-Pro and use some polymer for the body. The diff in image quality would be negligible. Crop sensors are cheap as dirt these days.

D_Gunman: The existence of this camera is to convince people to buy an actual Leica camera instead. Well play, Leica. Well play indeed.

Or a Fuji X-Pro3 for that matter ...

martindpr: Great. Now, 7artisans please make a copy at a $200 price range.

Now that the optical formula and the build are known, it would be easy for another company to replicate it. Might not be the sharpest replica but for a quarter of the price, it will do just fine.

martindpr: Here's a subject to investigate in one of your new videos: Can you make an AF digital RF (rangefinder) camera with manual as well as auto focus. Something of a hybrid between a Leica and a Fuji.

But still, it could be done.

Picture Leica RF with Fujifilm AF convenience. You want RF focusing, switch off AF, set it to MF. You need AF, you have the ultra modern fast and accurate focus. Wouldn't it be nice to have that in one body? Obviously, you would need an RF lens with an AF motor. Or reinventing Fuji's hybrid VF to offer a truer RF experience, since it's not a true RF.
