F-C: Thank you Chris & Jordan. I am interested in a video on tilting - particularly can tilting be used to increase depth of field? If so, in which circumstances is it more advantageous than standard lenses (focal length?)? I am in a stage of my life where I like to walk with just a camera and a lens (no tripod), can a tilt shift lens be used handheld?

AFAIU tilt neither increases nor decreases DoF but it tilts the plane of focus. Typically if you have objects on a table and you shoot them from an angle and want them all sharp, you tilt the plane of focus to coincide with the heads of the tin soldiers or whatever you have.If you want to increase DoF beyond acceptable or available minimum aperture, there's focus stacking.

To me tilt is a very special and rarely needed option and wouldn't consider that as a criterion for my only lens on a normal photo trip/walk. YMMV. A shift lens is another matter as I often shoot buildings or other objects I can't get centered in my line of view without unwanted perspective effect.

I'm sure there's an abundance of videos explaining both shift and tilt / the Scheimpflug effect.

Lovely camera for sure. Fortunately for us less well heeled we can have the Bayer filter stripped off many camera models for about 500 $/£/€ or buy a Sigma.

CekariYH: Do one need to read the text on the battery? ;-)

Looks like they printed the manual on it so it would always be with you.

JJSo: Has anyone of you ever seen a satisfying use of any HighRes mode? Be it Olympus, Leica/Panasonic or Pentax: I just see a lot of soft pixels. There's only one in the gallery, not with the best lens and presumably without tripod, but still, so far it doesn't appear to be a useful feature.

The G9 at least looks very impressive on DPR's test chart and Image Resource have a comparison with great looking hires output. I don't have any personal experience as I don't own a pixel shift hires camera but am quite keen on getting one.

Mr Bolton: These images look good, and look to be shot on the same day as the M43 100-400 Olympus tele review elsewhere on this site. They also don't look several thousand dollars (the price of an R5 and this lens) worth of better than an E-M5 III with its zoom. And f5.6 is f5.6 versus f11, with very similar Tonehs.

The Olympus setup is half the price for the same reach and two stops faster capture of the same Tonehs of bokeh. It's also smaller and lighter. Methinks the reports of M43 and Olympus' death are greatly exaggerated.

Paired with a canon rp i believe the combo would be cheaper+have a slightly larger aperture than Oly at the long end. OTOH the Oly is a zoom.

jvt: These cameras were very useful when film ruled the day. I was partial to the Olympus Stylus Epic (Mju II):
https://jimtardiophotography.blogspot.com/p/olympus-stylus-epic.html

I have a Yashica T4. Mine got wet on a kayaking trip but I had it repaired, which cost 1/2 of what I paid for the camera, not sure that was worth it, must have liked it. Now I think I will dig it up and see if it works. If it does, I'll sell it, I don't need an automatic anything film camera but might try my SLRs some day.

Wow, can't recall hearing about Yasuhara before. The Nikon is also a beauty. When it comes to film cameras I tend toward simplicity so been looking at the earlier Yashica D: no meter, separate cocking and winding. Preferably with the 4 element Yashinon lens though.

Rob-in-Alberta: i’m sick of Corona anything right now

I have a bottle of Gran Corona (red wine) in the cupboard. Will drink it when it's finally over, if it ever is.

Well said. One h*ll of a fusion reactor. Looks scary compared to the (mostly) benign lighter/warmer we see it as (at least on these latitudes). Yet it's supposed to go on supporting life for billions of years before it starts acting up.

GHebert: To many manufacturers, to many systems, including cellphones and not enough potential buyers. On top of it, big recession coming out from Covid19. Nature will take care of that problem. Heads will roll. Olympus will not be the last to abandon ship. And...Who would buy Olympus camera division? Panasonic???

indeed now starts speculation about who will be the ultimate owner(s). I'd like it to be Pana if they could somehow combine the best of both and make it all into a coherent whole and make it profitable. At least it would be an indication they are still serious about M43. OTOH they didn't buy it now and not sure how JIP is would make it attractive enough to anybody to resell at a profit. They are expected to 'sell pieces of technology' whatever that means. Maybe Pana is interested in some part... or not...

rurikw: I regretted giving away my father's Contax D although it was dead and the importer refused to touch it. The fact there are lots of them on eBay and I bought a Praktica FX eased the pain a bit but it's not the same thing obviously. Not sure what happened to the Ikophot light meter. But I have his slides which is of course much more important and one day I'll try to come to grips with his microscope.

Forgot to mention the fully working Biotar 58/2 that went with the defunct Contax.

rurikw: Looked like the G9's viewfinder has quite some pincushion distortion. Is it really that bad?

I shoot lots of stuff where lines should be parallel to the frame edges so afraid I might not get used. OTOH I mostly use the screen.

Thoughts R Us: I really like a quote from the website of the photographer, Burkhard Hillert, who did that photo of the refraction of light in a cobweb:

"The most creative artist is nature. I am only your medium."

Creationist rhetoric uses terms like 'random' and 'chance' to make evolution theory look ridiculous (as well as blasphemous). I'm not a biologist or any kind of scientist but as I see it chance is just one component. Mutations may indeed occur more or less randomly but then natural selection kicks in and 'chooses' which mutations get to survive. The range of random events is immense but restricted by the structure of DNA. I'm full of awe in front of nature and aware of the immense complexity and intricacy of the physical world and life in particular and that we still have only vague ideas about the beginnings of life. But I don't see how the concept of a creator could contribute in any way to our understanding. I see no other meaningful way than trudging on with research and add pieces to the infinite puzzle.

rurikw: 300W/s.=300J/s/s or 300J/s^2. What does this mean?

Thanks Ws being a unit of energy makes more sense. Not familiar with flashes but wanting to learn so curious. Now reading up on them.
