As it is with people who have too much money and time (I had an old contract, my rent was ridiculously low) the PEN E-P1 was soon not enough. But capitalism came top the rescue and offered me the PEN E-P3.
I bought this camera's predecessor as a secondary camera to my big Canon EOS 20D. But I liked the form factor and image quality so much that I soon sold all my Canon gear. But surely I would need the newest PEN camera, right? I just came into money after selling the old stuff. So one Amazon Prime delivery later, I was the proud owner of an Olympus PEN E-P3. I even treated myself to the expensive electronic viewfinder that goes on the hot shoe.
The camera was arguably better and more mature. I won't bore you with technical details, but this camera was much more usable. The display was better, the handling was more responsive and it gained a few useful functions on the way. The added viewfinder was an absolute delight. Sure it made the camera way less pocketable (like not at all) but it could be angled upward for low level shots for example. Unfortunately, the viewfinder was quite loose and I constantly lost it when I had the camera slung over my shoulder. Which pretty much led me to buy the next camera. I used this camera only in 2013 and took (kept) about a hundred photos.
I also used this camera to experiment with the different built-in filters and effects. Something that I find slightly gimmicky from today's perspective. But Olympus put a lot of these filters in their cameras. Rumors are that they sold well with Japanese customers. So I chose images with a filter applied, even though I would certainly not use them today.
