If you are a full time stock photographer then riches and fame will elude you. A life of anonymity awaits and you have to get used to the fact that your blandest images will sell the most and much of the time you won't even get a credit for your images that are buried underneath a pile of poorly written text in some junk mail brochure that people consign to the recycling bin as quickly as possible. But there is an upside. You get to shoot what you want, when you want and how you want. If you also love the freedom to experiment, to have fun with and yes, play with your cameras and lenses AND get paid for it, then this is the job for you. I think it's the best 'career' in the world and any idea that I actually work for a living is far from the truth. I get to indulge my whims, spend my days wandering about where I want and creating images that I like. Sure there is the tedium of editing, captioning, keywording and uploading, but that is a small price to pay for the freedom of doing what I do.
For no obvious reason other than I felt like doing it, I bought a S/H Voigtlander Nokton f/1.1 lens, a Novoflex Leica M > Leica T mount adapter and stuck both of them onto my Leica SL (Typ 601) and had a wander round Stratford-upon-Avon on a sunny afternoon. I did of course shoot some images at f/1.1, vignetting and all and decided not to fix that in Photoshop. I got some images I liked, uploaded a few to my stock libraries and the day after decided to do something else. Yes, it's a rotten job, but somebody has to do it!!
