You need no more lens because if you did, you would not be asking this question. Stop buying until you figure out what you "need" otherwise you will soon end up with a bunch of duplicated and overlapped lenses. I know I don't sound pretty btw.

for small and cool, get the da40.

but if i had what you have, i think i'd try the 10-17 fisheye because of the fun factor.

unless if you really need AF, then go for the DA40. otherwise, don't buy at all since you are pretty much covered.

if you are going to ask what I really think, dont buy any lenses and practice and shoot with what you have right now. shooting mf is fun and would improve your skills especially if you are a beginner, well even if you are experienced already. and unless you have a serious eye defect that requires the assistance of AF, then buy one.

Fully agree. You already have a lot of lenses. If you are a beginner, start to use your lenses and to experiment with your gear.

You could spend $1,000s in equipment, but you do not need much to do some good shots. Real photography is about using your camera ...

You will hate the FA 50mm if you think the M 50mm @ F/1.7 is soft. Maybe you dont know, but chances are your missing the focus considering the extremely shallow DOF and MF. The FA 50mm is softer at F/1.7 compared to the M 50mm at F/1.7 but it is about perfect for portraits (never want to be to sharp for portraits). Get the 40mm, as it by all accounts is sharp wideopen.

A vote for the DA40

One of the advantages of Pentax is being able to own lenses from different eras that have different optical qualities and can create different moods. I own the DA 40, FA 50 f1.4, and an A 50 f2. The DA 40 is so sharp and contrasty, while the FA 50 f1.2 is a nice portrait lens. The A 50 f2 is not a great lens, but it offers a different look from the others, and delivers high detail images at middle f stops. It's similar to the M 28 f2.8 that you (and I) own.

Being that you don't currently have a DA limited, I recommend the DA 40. It will create images that will pop like no other lens you own.

You guys are being way too harsh. Let the newbie succumb to LBA It's fun and educational.

My advice: Get the FA 50mm 1.4. It overlaps your M 50, but there's nothing like a fast autofocus 1.4 for available light photography. You'll probably sell your M 50 after you get this one. While it is soft, it certainly sharpens up with better lighting/adjusted f stop. When I shoot RAW, I'm able to massage the "pixie dust" and extreme sharpness out of the lens. Summarily, it's a great workhorse lens.

That said, the DA 40 is a very competent lens, small, fun to use, and it has a bit of "pixie dust" thrown into it's image rendering for really vibrant images straight out of the camera. But I've used my FA 50 much more so far.

Let me put it this way: I haven't used the FA50 much since I got the DA40. Every time I'm about to reach for the FA50, I get the DA40 instead.

The DA40 is slower but I'd rather bump up the ISO and deal with noise in post processing.

The DA40 is small, fast focusing, contrasty, and quiet.

Oh, did I tell you that the DA40 is the sharpest lens I have?
