Originally posted by Craigbob So I'm on the hunt for an 85mm 1.4 for my K-1. I want autofocus so that lets out the Samyank/Rokinons. I've found a couple of options that are in my price range. I've found an FA* 85 1.4 in great condition and the Sigma 85mm f1.4 EX DG HSM.
While I'd love to get the new HD D-FA 85, it's way outside my budget. Between the Sigma and the FA* which is the better lens in terms of Image quality and sharpness. The reviews up here give a very slight edge to the FA* 9.72 vs 9.2. I can get the sigma for about $200 less than the FA*. I 've had sigmas in the past (for my Canon) and been disappointed by the image quality. So I'm really on the horns of a delimma here.
Any advice is appreciated.
Do you require weather sealing for your projected uses? If so, I think you need to go Pentax regardless of cost. For a studio lens, that's an entirely different matter.
If much older lenses are OK, I have seen film era Pentax SMC 85mm 1.4's for in the range of 500USD. Some are manual focus. Keep watching the marketplace. In particular, there is one seller there who pretty specializes in older Pentax lenses. Again, many are manual if that's an issue for you.
