Hi All, I've seen a few Pentax users in various threads lately so I thought I might try my luck asking here. I'm currently after a low light lens for use in restaurants, indoors and such without a flash. All this time I've been looking at the FA 50mm f1.4, I currently own a manual focus f1.7 but find I miss too many shots (not enough time to focus). However I've read about the limited series and their image and great build quality etc and seen them in some of your signatures. Problem is, at a slower f2.8 is there any advantage or point in spending the extra? How is the f1.4 in terms of build and image quality? I have an old SMC Pentax powerzoom that I never use that looks similar to the FA f1.4 50mm, my powerzoom feels cheap and plastic, wondering if it is the same for the f1.4. Any great reason why I should go for a limited DA lens instead? I understand they are a stop or two slower, do they still perform well indoors? If so which would you recommend or do you like using most? Any help or suggestions would be greatly appreciated, Thanks.
