Ralf11 Posted June 8, 2019 Author Share Posted June 8, 2019 yes, film is obsolete now, what speaker is analogous to my Hasselblad 500 C/M ?? and what speaker is is analogous to my Nikon F3?? *which I don't shoot but you will still have to "pry it from my cold, dead fingers") Link to comment
Ralf11 Posted June 9, 2019 Author Share Posted June 9, 2019 The Zone System - I think everyone with a camera should read it it is a way to think about, and characterize, the Dynamic Range of a scene, as rendered on film or a sensor - it is needed (for one reason) because the eye has a DR that greatly exceeds that of any film or sensor, much less a print Link to comment
Ralf11 Posted June 10, 2019 Author Share Posted June 10, 2019 with digital, it is cheap & easy to exposure bracket and stack in post I also hear that there will soon be a way to unfold all your film shadows using MQA Link to comment
Ralf11 Posted June 10, 2019 Author Share Posted June 10, 2019 I do think it is possible, but to use esldude's patented phrase it would be irrelevantware. I keep over-exposing things with my Hasselblad (using a m43 camera as a light meter) so my relevant question now is which 120 roll print film has the greatest DR, and how many stops off am I...

Ralf11 Posted June 12, 2019 Author Share Posted June 12, 2019 I already have some 18% gray cards - it costs $0+ to do a test run, and being a cheapskate, I am just shooting brackets. Link to comment
Ralf11 Posted June 16, 2019 Author Share Posted June 16, 2019 Let me recommend a book. Tho old, it is not at all dated: https://www.springer.com/gp/book/9781468420395 As someone interested in organismal performance, I found this revelatory even tho it was not part of a core research interest (at least when I read it). If you are on the biology (or robotics, or AI, etc.) faculty at Deep State Univ. it will serve you well. Well back to HDR merging of exposure bracketed pics I took with my puny m43 sensor...

Ralf11 Posted June 18, 2019 Author Share Posted June 18, 2019 I dropped FF and went to m43 (with Leica lenses) Link to comment
Ralf11 Posted June 18, 2019 Author Share Posted June 18, 2019 5 hours ago, daverich4 said: If your camera is made by Panasonic, those lenses are licensed from Leica, not made by them. I have the 12-60 “Leica” lens for my GX8 but it’s nowhere close in price or image quality compared to an actual Leica lens. that is why I put Leica in italics above - AFAIK, the lenses are designed by Leica, manf. by Panny, and then checked by a Leica team inside the factory if you have any lens test data, or side by side imaging comparisons on L vs. P-L lenses, I'd be interested in seeing it Link to comment
Ralf11 Posted June 18, 2019 Author Share Posted June 18, 2019 Yes, I know about the replace only thing - one factor keeping Panasonic from being a viable replacement for a pro co. like Nicanon. I like m43 as it is a LOT smaller & lighter, so I am more likely to carry it with me and consequently get certain landscape shots. I still have the Hassy film camera (mostly just to hear the mirror thunk, which I find very euphonic) and recently spent a kilobuck to get it CLA'd. I also kept some Nikon stuff, mostly old MF lenses and 2-3 bodies - micro lenses, and the famed "nice old fashioned glow" of bokeh from the 50/1.2 and 45/1.4 I do think the PL 12-60 is a good replacement for the 24-70 Nikkor, and some other adv. amateurs have also sold their Nikons. One is a friend and colleague whom I follow in photographic matters - via the "you first principle." For example, I let him buy the Series 1 Nikon gear then watched as he dumped it after Nikon dumped the system - many $$$ down the rat hole. daverich4 1 Link to comment
Ralf11 Posted June 19, 2019 Author Share Posted June 19, 2019 sadly, I made a typo - it is the 35/1.4 MF Nikkor https://www.casualphotophile.com/2017/01/16/nikon-nikkor-35mm-f1-4-the-fastest-35mm-nikon-lens-ever/ the Micro Nikkors I kept are MF 55mm - one compensating & one not: https://www.dpreview.com/forums/post/55256540 I also have a kit zoom 24-85 AF-S, a screw drive 100mm micro, pre-Ai 24mm, and 2-3 50mm lenses. I have the 80-400 AF-S tele zoom also, but will try to sell it and get the 100-400 (200-800mm equiv.) Panny-Leica. Link to comment
Ralf11 Posted June 20, 2019 Author Share Posted June 20, 2019 I'd sell 5 & 6... but I like macro work Link to comment
Ralf11 Posted June 20, 2019 Author Share Posted June 20, 2019 both negative posts above relate to Leica being a small manf. - once you leave Mechano-land and move into the world of electronics, big co.s are able to deploy teams o engineers to create fast focus motors (not to mention CAE optical designs) both Zeiss & Leica have teamed up with large co.s to help address this the same thing applies to cars: Porsche got along for several decades by generating income for their engineering staff to design for other car co.s - only about half the income of P AG was from the car division, with the rest from the design firm staff Today, large co.s in Japan are eating away VWAG, MD, and even BMW who used to won the luxury market - but what is a luxury car today?

Ralf11 Posted June 21, 2019 Author Share Posted June 21, 2019 one issue w.r.to lens 'quality' is that people often focus on a single factor - sharpness today, people expect super sharpness corner to corner; in ye olden daze only center sharpness was the ... ah... focus but many other factors are involved, including chromatic aberration, contrast & etc. Leica lenses are said to have xlnt. contrast there is also bokeh and other aspects of 'rendering' (the reason I kept my old MF Nikkors, and covet a 'feather bokeh' Olympus portrait lens - despite the fact that all my female friends are too old to be subjects for one...) Finally, there is the use of the lens in the field - nano-coating is a key factor for reduction in flare, as was multi-coating soe years ago then there is the 'flocking' inside the lens - IIRC, the later Zeiss/Hassy lenses (maybe the CF series?) had an upgraded flocking to reduce flare from diffuse sunlight (not just a beam in the field of view) - this is something that would apply for outdoors use, not indoors Link to comment
Ralf11 Posted June 23, 2019 Author Share Posted June 23, 2019 the new small Hassy is getting news & reviews all over the internet That said, I just got back from some pic-taking adjacent to a lava flow and only took my m43 gear... also had to listen to crummy Subaru car stereo on the trip.

Ralf11 Posted June 24, 2019 Author Share Posted June 24, 2019 well, there is also the mirror movement... Link to comment
Ralf11 Posted June 24, 2019 Author Share Posted June 24, 2019 ok, the Hassy film body is a box with a moving mirror that connects to the film back and lens - all built to very high precision like a Swiss watch Link to comment
Ralf11 Posted June 25, 2019 Author Share Posted June 25, 2019 There are a lot of parallels between cameras and HiFi sound... both are distance sensory systems & use a fair degree of neural processing, require amplification... both technologies have undergone a rapid change, approximating a step function, from digital techniques both tend to be hobbies but both have a pro component Link to comment
Ralf11 Posted June 25, 2019 Author Share Posted June 25, 2019 True, but what about all the talk I see about micro-contrast? It never seems to be described, much less defined... is it crazy talk? But I won't argue against your point, as that's the only possible example I can think of. Link to comment
Ralf11 Posted June 26, 2019 Author Share Posted June 26, 2019 OTOH, I often see photographers insisting that measurements are not important... Link to comment

Ralf11 Posted June 27, 2019 Author Share Posted June 27, 2019 34 minutes ago, charlesphoto said: Eyes and ears are different in their sensitivities - but we all know that, don't we? ... No, I don't know that. First, is the issue of how different sensory modalities can even be compared. Second, one valid answer is that one could compare how close they come (how close they have evolved) to a perfect sensor that is limited only by physics, no matter how constructed. The human ear is so close that it is noise limited (by air molecules bouncing off the ear drum - according to some older research). The human eye is also very close to a perfect quantum device (IIRC, I posted a cite to Albert Rose's book above or in another thread). He considered film cameras, video cameras and the vertebrate eye, comparing them all as only a Bell labs research scientist could do. So, this means they are quite close in sensitivity, using evolution to a limit of the physical universe as a metric. jabbr 1 Link to comment
