I[‘ve Just taken delivery one month ahead of schedule! of my new TT Artisans 17mm f/1.4 lens. My friend Jimmy Cheng was right, this lens is very sharp. My only slight criticism and it’s not a big one and something that I’ve noticed with other Chinese MFT lenses is that it is a very tight fit but the quality, especially stopped down to about f/5.6 is outstanding and no hit of chromatic aberation!, I’m impressed and looking forward to being able to get out and properly put it through its paces. A quick test pic as I ‘m housebound today. and a 100% crop.
