I bought a Moskva 5 some months ago and have only put a couple of rolls of film through it since I bought it. I'm sure many of you already know this, but this is for those of you who don't. The earlier Moskva 2 and 4 models were Russian knock-offs of the Zeiss Super Ikonta C, a 6 x 9 folder with coupled rangefinder. The Moskva 5 is basically a restyled 4 with a one-piece top cover. These cameras are, from an optical standpoint, very good copies of the Super Ikontas, although they are somewhat crude in construction. My 5 has seen a fair amount of use and not everything works as it should. To open it up, pressing the button on top doesn't work. I have to give the body a good tap and it then springs open. When you open up a Super Ikonta, the front standard smoothly runs out to its stop and locks in place, assuring the lens axis is perpendicular to the film plane. When you open up this Moskva 5 of mine, it takes another little rap to coax the front standard out to its final stop.
After looking at the images I don't think I locked the lens all the way forward for a few of the shots. With at least a couple of the images, most of the image was sharply in focus, but a large portion of one corner was out of focus. Most of the images didn't exhibit this problem. So I blame myself for not insuring that the front standard was locked in place all the way forward.
All three of the following images are crops. Two are just slight crops, for slightly better framing, and one I cropped more to eliminate a blurry corner, caused by the front standard not being locked down.
The film was Tri-X, developed in D-76. I used my Gossen Luna Pro F to determine exposure.
We had a hard freeze here in Houston in January. This bird bath was frozen solid as a result. Note the blurry upper right corner. Even though this was a crop, I couldn't eliminate the blur entirely. But check out all the detail below the bird bath.
We left our outside faucets to drip, to avoid the risk of frozen pipes. The results were some interesting ice formations.
I don't really know why I focused on the neighbor's funky looking garden patch, unless maybe I didn't calculate the hyperfocal setting correctly. I dunno. But at least there's good definition in her shrubs.
