Lord Powershoter: Does this seriously not have a moveable screen? Or am I Just not seeing it? Saving space couldn't have been a priority.

It's a feature. You tilt the camera.

yes, and mushroom detection as well

I haven't read all comments, but looks like bokeh has not been mentioned.
Dirt/scratches on lens elements can show up in the bokeh really strongly, e.g., in out of focus light circles. Sometimes appearing very sharp and strong (probably because the out of focus light is actually in focus somewhere in the lens, but not at the aperture level). A test could be added to the review.

Mister Anders0n: Also, this lens appears to be fixed focus? I see in the video review on their site that the focus ring actually just controls magnification (1:1, 2:1, etc). So once it's set to your goal, say 5:1, you can't actually adjust focus? Looks like you need to physically move the camera or subject?

That's very normal at high magnifications that you actually move the whole body and lens on a rack back and forth to achieve focus, like on a microscope. Modern macro lenses with AF that go to "only" 1:1 magnification have internal focusing, so the body does not need to change position. But as you noticed, that causes actually rather substantial focus breathing, I think a Canon EF 100mm L macro goes down to about 60mm at 1:1. Old macro lenses, like e.g. a Canon FD 100mm/f4 did not do that, you just had to keep extending the lenses more and more to go down to 1:1, with the result that the body had to be moved further and further away in the process. Also with such a set-up, one is better off to simply set the desired magnification, and the focus by moving the whole system back and forth. Old magnification bellows have rails to move both lens alone, and the setup as a unit.

finally somebody did it, that idea was going around for quite a while.

drummercam: Some hallmarks of Pentax top-of-class cameras are in place: green button (a highly under-appreciated feature of Pentax cams) is on back, not on top. ISO button is on top, not on four-way. IR-port present on back side as well as front (very useful!). Separate AF and AE-L buttons. Built in stereo mic, and microphone port AND headphone port at left.

Looks like a beauty that no doubt will equal or exceed IQ and low-noise of the KP. Looks more like K-S2 sized than the K-3's but probably has the LI90 battery in that grip. Built in stereo mic, and microphone port AND headphone port at left.

I like it, and it will no doubt be as robust as this K-3 I've dropped and dunked to no ill effect.

does the green button save CO2? ;-)

CekariYH: I have wished for a few more buttons on my a7R III and soon 7R IV, but this takes the price, buttons etc everywhere, looks like some kind of receiver :-)

Probably a great moviemaker never the less.

Actually, yes, I was wondering if one can use it as an accordion as well... ;-)

Get a cheap bellows on eBay, attach a pinhole at the front, and one has a much larger focal range.

@Carey Rose. Thanks. I have seen other places where there is a trend to videos (instead of text), which I find horrible and inefficient. I hope dpreview keeps the text versions.

at Revenant. Yes, I saw the TV part, but the title itself said "review" not Videoreview. Further, there was a clickable contents list, which suggested a text oriented review. Also, the test scene is there and published. Given the effort put into this TV review, I expect that no written review will come for the SL3. Maybe that is the planned future for reviews. Not for me.

bilmenot: There is nothing exciting to write home about, was it not camera and lenses were designed for FF on day one ? then it came APS film format which was short lived, then we have digital, due to the high cost and difficulties to produce we don't have FF digital until recent years. Now the dust settled and camera and lens makers returning to their old business to produce FF products. FF camera and lenses not necessary to be big, remember Olympus produced the smallest FF SLR (NOT mirrorless !) and lenses, with modern technology I believe we can shrink the lenses and electronics into small package not much bigger than APS format, eventually APS-C will be replaced by FF as the cost drops.

I am with you. In the film days I had a set of lenses for a FF SLR camera, and that whole set was less than 2 kg. Now, I have an APS-C dSLR with some lenses, in the same weight range, and I do not wish to carry more. The FF body can still be made relatively compact, but with the increased demand on image quality, the lenses have become much bigger. Classical 50mm f1.4 lenses are quite small and light, but the IQ is not good wide open. Now f1.4 or f1.8 fixed lenses are excellent, but start to be ridiculous in size & weight, because of all the glas elements to correct all the optical aberrations. Same for FF zooms. And you can't make the lenses smaller that easily, unless you sacrifice IQ. So, I think the APS-C market will stay.

In reply to:

entoman: Now that all cameras are becoming more and more "equal", it will be interesting to see what new tech unfolds to prompt new camera purchases.

If we got organic sensors I'd be really pleased, as images would lose that "digital" look, and noise patterns would be far less obvious.

AI technology is clearly going to be the next "big thing", with object recognition (OR). Much of the skill will be taken away from the photographer and handed over to the camera, but think of the possibilities:

Soon, OR will not just recognise the subject - it will also recognise the degree of *movement* in the subject, and set an appropriate shutter speed.

Soon also it will be able to automatically recognise a "fussy" background, and choose an aperture (or "fake bokeh" setting) to render it as a blur.

Soon it will "learn" how to crop poorly exposed images automatically in-camera, to improve composition.

Soon it will be able to recognise different subjects, label them and put them in different folders.

and soon it will be mounted on a drone that travels. to locations with a self driving car, while you sit at home

These images are part of human history. The horrors of slavery should not be forgotten. The book is part of an educational museum exhibit tour about photographic documentation through time. Photographs of people were part of anthropology in it's infancy - actually, anthropologists still do this of tribes that have little contact with civilisation today. It's part of human history that's being documented. In a way it's comparable to holocaust museums with images, to remind one of those horrors that should never be forgotten. Renty's descendants should be proud that their ancestors are part of history. Instead, it seems the only thing that counts these days is $.

In reply to:

deep7: Wow, heaps of comments poking fun at "hipsters". Yet there are endless stereotypes in most societies. For example, plenty of blokes run around with short hair, bald faces, wearing identikit suits and ties (a more common example of dressing/styling to fit into a clique). You don't see them complaining that a photo of another dull man in a suit is actually them. I'd give this bloke credit that he actually looked at the face in the picture before complaining. Surely...

Monty Python made fun of guys in suits already a long time ago.
