I started out with an entree level DSLR camera from Canon. I choose Canon because there are so many cheap lenses available, second hand but also from third parties, like Tamron, Sigma and Rokinon. I just tried different lenses, but also things like a reversal ring or extension tube, m42 adapter, polarizer filters and many other things. That is how I rolled into astro photography, whereas nowadays I’m more into bird photography. My advice, just play around and experience what you like the best. Expensive gear is oftentimes not the answer.
I make photo albums of a selection of all the photos I take and then show it to anyone who wants to see it. During holidays I also take video, and then combine those clips with photos into a home video. I have printed some photos to hang on the wall, so my home is filled with my own photos. I have some as desktop wallpaper. Lately, I make theme photo albums. I have one with all the different birds I have photographed and one with all my prettiest photos.
Sure go ahead! I was always interested in the technical side which made me pursue the route with adapters and different types of lenses. I hope you find what makes you happy :)
