so if you put a phone on a #screen, you risk scratching the screen. if you put a #phone on a #camera, you risk scratching the camera.
is it already a well known fact, that default sailfish camera on xa2 gives a choice of 16mpx (16:9) or 13mpx (4:3), while piggz’ camera: 5984x3392 (187x106) max, which is 19 mpx? at the same time lineage os default camera gives: 22.9mpx (4:3) and 20.2 mpx (when using 16:9 resolution), strange.

tells that ccd colours and picture details are much bettec, is it the case?

also, its interesting, that he tells that the camera is very power efficient because it has no motor to move the shutter, but the lever.

p. s. how can i remain silent that i know the camera since long time ago, and i wanted to get it for my collection, but it was too expensive, and somehow unreasonable. (:

apparently (british scientists found out), that it’s much easier to try to fix a camera like this rather than a much ‘simpler’ plastic compact like this. because the latter has flash, therefore it has a pretty big capacitor, therefore, it makes an electric shock to you whether you accidentally touch some contacts on board. well, several times. also, the former camera is more like a clock, you can understand how it works after some time of tinkering. the latter one remains a complete mistery. or misery. #kodak #camera
just fixed the stuck shutter of porst compact reflex sp (: because how hard could it be? (:
btw the camera itself is a piece of art. and lightmeter lights panel in the viewfinder with arrows and green led looks quite impressive today.
because good design is out of time. (:

this case belonged to someone’s mother. she wrote there the date when she came to yerevan to obtain the camera.

My friends helped me to measure radioactivity of my lenses. I had some yellowish lenses, and had an assumptions that some of them are possibly radioactive. However, I did not know until this time if it’s true.
These are the results of our measurments. We have been written down only the maximum values.
I am not able to disclose information about the person who conducted the measurments, the place, and even the device name.
| background | front el. ( μSv/h) | rear el. ( μSv/h) | ||
|---|---|---|---|---|
| Asahi | Pentax Super-Takumar | 35/3.5 | 0.08 | 0.08 |

| Helios(KMZ) | 40-2 | 85/1.5 | 0.062 | 0.089 |
| Industar | Industar-61 (i-61) (FED-3 lenses, lanthanum optics) | 55/2.8 | 0.085 | 0.085 |
| Mamiya | AUTO Mamiya/Sekor (DTL series) (identified thorium-232) | 50/1.8 | 0.24 | 1.164 |
| Mamiya | AUTO Mamiya/Sekor | 55/1.4 | 0.09 | 0.09 |

Apparently, Mamiya/Sekor 55mm which is reported to be radioactive[1] is not active according to our measurments. May be there been different 55mm f1.4 lenses in production?
The only really dangerous lenses we found in my collection were Mamiya/Sekor 50mm f1.8 which came with my Mamiya 1000 DTL. It’s also yellow. The device could identify the radioactive element, which is, no wonder notorious Thorium-232.
When measuring Helios 85mm, the radiation level went lower than the background, when the device got closer to the glass: that’s because it’s built from solid metal, and it filters background radiation at it’s front part which has small hood. These lenses are also a bit yellow.
What was surprising, that lenses from the FED-3 camera, officially promoted as lenses with lanthanum optics, seem to have no dangerous level of radiation.
We have also measured the Mamiya-1000 DTL viewfinder, and FED-3 viewfinder, they are clean and safe to use.
Another test we conducted - we were trying to get the device notice the radiation when the thoriated lenses were on the camera. We could not detect radiation by moving the device sensor arond the lenses, near m42 mount, everywhere around the camera. It seems that the metal parts filter radiation well, and even those lenses are safe to use.
I may update this information here

apparently there was a digital rangfinder, which looks like bessa voigtlander, and probably is modified version of it. it had aps-c sensor with 6.1 mpx resolution. it was produced since 2004 till 2007. amazing.

banal still life with camera and cola cup. at empty vanadzorian kfc. i hope it won’t be closed. it’s good there is one.
this is not a camera, and this is not a cola. the left cola is doubly not cola.

this works as a flag - indeed very useful to not forget that there’s a film inside, and which is the speed of the film.

it turned out, it’s possible to use polaroid back with some medium format cameras.

This test proved to me several things. First, c.1956 Rolleiflex Twin Lens Reflex cameras can keep up with modern photographic equipment. Let me put this another way; I’m blown away by the fact that a 50 year old single coated lens camera can produce large prints that show as much fine resolution and detail as the best modern multicoated lens that I currently own. Both Rolleiflex tested at 96 lines per mm against the USAF Resolution test chart. This equals the newer Zeiss Planar optics in the Hasselblad. Both Rolleiflex controlled flare better than the 500CM too. In practical use, a photographer would be very hard pressed to tell the difference between images taken with c.1956 Rolleiflex and the latest greatest mulitcoated wonder-camera. In oh so many ways, this was a staggering realization.
My tried and true Mamiya 7 travel companion came shining through. I had assumed its optics were slightly less contrasty than the Hasselblads 80mm CT* Planar. With the possible exception of its interchangable film backs, I no longer feel that I’m missing something now that I sold the beautiful 500CM. While Mamiya has made consistantly fine camera equipment, I somehow believed that the Hasselblad was a sharper, more constrasty solution. In this test, the Mamiya 7 is the hands down winner on all accounts. On this day, there was none better. But there were these two little 50 year old cameras that gave the young pups on the block a good run for their money. I knew there was a reason I needed to give Rolleiflex twin lens reflex a third try. I’m glad I did.
