Vivitar V3800N: Film memo holder

This is a box of photographic film.

You can cut off part of the box:

And insert it into a square window on the back of the Vivitar V3800N (to remember ISO and the number of frames):

This window is a film memo holder for a part of a box or for some other memo information.

Warning: A memo can only be inserted or removed when the back is open. When the back is closed, the eyepiece blocks access to the memo.

The lenses I disliked the most were the Mir-1V and the Jupiter-9, although I tried several copies. They were bad both mechanically and optically. Maybe earlier ("silver") versions are better, but I don't want to check.

Cujo 1: Right crank arm (again)

The right crank arm (of my Cannondale Cujo 1) loosened, again. A common problem with the FSA Comet crankset.

I tightened the crank bolt with a 10mm hex wrench.

Staeble-Werk Choro R 35/4.5: Samples [2] - APS-C - f/4.5

Photos taken with the Samsung NX10 (1.5x crop factor, 14.6MP) and the Staeble-Werk Choro R 35/4.5 at f/4.5.

Note that color vignetting ("color shift") is much less than on the Samsung NX2000. This is an advantage of the older 14.6MP sensor over the newer 20MP [APS-C] sensors of the Samsung NX series.

However, manual focusing on the NX10 is difficult due to the insufficient live image magnification.

Vivitar V3800N: More details

The Vivitar V3800N 135 film camera has a Pentax K mount without electronics, it supports the stop-down indicator.

So you have to set the aperture on a lens. This is unusual for me after Pentax digital cameras, which had no stop-down indicator support.

The film advance lever has two "neutral" positions:

And it is not a power switch (unlike some cameras).

The self-timer flips the mirror up before the picture is taken. This is useful when using a tripod.

But the self-timer lever feels very cheap and fragile. I prefer not to use it to avoid breaking it.

The camera has a fully mechanical shutter with good characteristics: 1/2000 fastest shutter speed and 1/125 x-sync.

The camera operates without a battery. The battery is only needed for the TTL light meter. To use the TTL meter, you should install two LR44 batteries:

LR44 batteries are cheap and easy to find.

To activate the TTL light meter, press the shutter button halfway down. There is also a button near the pentaprism cover.

This button also activates the TTL light meter. And it is very convenient. When you rotate the aperture ring, you can press the shutter button. But when you turn the shutter speed dial, it comes in handy to press the "meter" button.

Also note the depth-of-field preview lever.  But be careful with your thumb or finger, the DOF preview lever moves when the shutter is released.

Another key feature of the Vivitar V3800N is Multi-Exposure. There is a button (near the v3800N label):

While the multi-exposure button is pressed, the film does not advance when the film advance lever is moved. Only the shutter is cocked.

The camera is easy and intuitive to use. The only thing I read in the manual was how to set the film speed (ISO). To do this, you have to lift up and turn the film speed dial (of course, there is no DX code support).
