I recently took delivery of two TT Artisan manual focus lenses for MFT, the 17mm f/1.4 and a 35mm f/1.4. I took them and my PEN-F for a photo walk in Littlehampton close to where we live and I'm pretty impressed with their build quality and sharpness especially as they are both extremely affordable.
A few pics, the first two taken with the 17mm and the second two with the 35mm.
Kind regards
