>>3773118sadly I either miss focused significantly, or that speed booster just doesnt like the 14mm Art. Its a blurry mess. this was a 150mm f/2.8, with the teleconverter and speed booster on, just to see how horrible the image would be. it is surprisingly not as bad as I thought it would be, with the main problems being back focused because she was moving around while I was trying to pull focus, since the speed booster doesnt have electrical contacts.
