I bought an additional battery, an M42-Nikon adapter with a lens, several ancient "screwdriver" lenses from film cameras. Old Soviet "fixes" struck with fantastic quality! It's just a renaissance of Soviet optics! A set of "screwdrivers" from old film cameras is also pleasing - they have zoom lenses, processors, and sufficient resolution. All the previous 38 years in photography I twisted the "focus" with my hands - I'm already used to "Puff" I use it very rarely - I prefer a tripod and slow shutter speed. In general, a camera for "big-headed" and "handy" photographers - it doesn't matter if they are "pros" or just amateurs. Good for landscapes, macro, still life, astrophotography. For astronomy, you will have to get good "pipes" (for example, "MTO"), guiding mounts, and stock up on "exposure" .
