It's a camera you tend to either love or hate.
I have an 88 with the 45, 65, 80, 120, 150 and 250 lenses and I enjoy using it, despite all its idiosyncrasies.
The leather smells weird, the methodology of operation is byzantine and there can be some irregularities with the shutter at higher speeds, but... who's perfect?
I like most older Russian cameras, because they are so unique; true mechanical cameras with some strange quirks. However, if you operate them correctly, the results can be quite nice.
If you have no tolerance for quirky behaviour, or rely on your camera to make a living, I would suggest you avoid this camera. But, if you can stand a bit of uncertainty and are open to some degree of variation, they can perform very nicely and provide outstanding results.
