Change from 40mm limited

I recently had a Tamron 17-50 2.8 which I though was a bit too noisy, slow af and not super sharp, I sold that lens and bought a 40mm limited.
I think that the 40 is a bit too narrow for a prime for me and was thinking about what could replace it.
If I analyze my photos from the past, most photos are taken at around 18 or 50 mm (probably has alot to do with all my quick snaps and candid photos are taken at the widest end of my 18-135 or 17-50 and all portraits are at 50mm, with the 17-50).

The size of the 40 mm or 21mm is of course nice but not super important, I value the image quality more.

What would you go for instead of the 40 mm limited?
- 21mm (for walk around) plus a 50 1.8 (for portraits)
- 30 mm 1.4 sigma
- ~17-~50 Tamron/Sigma (I like the HSM in the Sigmas..)

I would love to go for more limiteds but that would be far more than I want to spend. I'm looking to spend what I can sell the 40 for plus ~200 usd (I wouldn't mind buying used)

Well I guess that you want some wider but mostly better IQ.

- FA31mm/f1.8
- DA*55mm/f1.4

Can't go wrong with those two.

That would be perfect but way over my budget I'm afraid.

Hmm, you didn't like the Tamron you sold, so no sense buying it again.

The 21 has a lot of barrel distortion, and as a prime is not what I consider a walk around lens.

The Sigma 17-70 gives you a better range with good IQ, and has the benefit of close focusing,

The DA35 F/2.4 is much less expensive.

Honestly I think many people would recommend the Tamron for your situation!

I have the Sigma 30/1.4 and love it. I don't usually care about corners, though, just not important in my shooting style. I also have the 40, and when I really need sharp corner to corner, it's my go-to lens, but I favor the Sigma significantly.

I have the 21, and love that too, but it's just a hair too wide for all the time. The 30 is my just right FL.

For walking around, I like to carry the 15, my Sigma and a fast 50 (manual focus, I have several). When I'm with the family, I keep my 18-135 on the camera, with the 30 in the bag for dark places or shallow DOF. Either way, the 30's always in the bag.

-- You did not like the zoom.
-- Your pictures are usually 18 and 50mm.
Seems obvious of the choices the prime 21mm and 50mm. Wider primes are generally costly or not so good.
If you use MF there are many lovely inexpensive 50mm. E.g., 50mm M f/1.7,

BTW to keep your future options open I would suggest getting the 50mm w/ an aperture ring. If you get into close up/macro it makes a big difference (usable w/ [regular] extension tubes, teleconverter, and bellows; and reverse the lens; etc.).

To help you decide I'd suggest a Tamron 28-75 f/2.8 - they come up often enough in the Marketplace, will fill much of your chosen range and it's quite a good lens!

Lens suggestions

I have the Tamron 17-50, and have not found it noisy, but I have not used it with high ISO. I love it for low-light and night shots. On the other hand, I also have a Pentax FA 24-90mm, f 3.5-4.5, which I select over the Tamron when image quality is the objective. The lens is not seen very often for some reason, but is generally highly reviewed, and could be what you are looking for. I see there are a couple on eBay at the moment for $300+, probably a fair price.

I have a Sigma 17-70 which is my main go-to lens when I want convenience. I also have the 21 and 40. I'd say the two work very well together, so you could consider keeping the 40 and adding a 21 to the lot, so you'd have a combo. I personally find 50 too tight, however, you might feel different.

One other option could be to go with a 35 if 40 is "a bit" too narrow for you. Or find a used FA28, it's an excellent lens.

Hmm, interesting comment given that I usually hear most people say that the Tamron 17-50 is a very sharp lens. I've never owned one however. Anyway, for your budget and your requirements, it sounds like the Sigma 17-50 HSM would be ideal-- you might be able to snag one used for $500 or less if you're patient and look around a bit.

Otherwise a FA 28 or F 28 makes for a nice walkaround prime, very sharp, and combine that with a FA 50 or DA 70 for portraits.

When I used my Tamron 17-50/2.8 A16 with PDAF on my K-x,
I would also often be disappointed by the lack of sharpness,
especially at the wider end.

However, once I started using CDAF in live view for focusing,
it was a whole different story.
Suddenly, the lens revealed its full potential.

So, since you're finding a 40mm prime too restrictive,
I'd suggest giving the Tammy another chance.

focussing the Tamron 17-50, 2.8

Yes, much as I love Pentax, fast and accurate focussing is not one of the features I brag about for my K-01, K-20, K-7, or K-5II. However, the nice thing is that the cameras all have an M setting for manual focus. Some have live view focussing, and others have green dot in viewfinder. Most can be programmed to give an audible bip when focussed, and for some lens, catch in focus is available. The more I use all these focussing aids (plus the split prism focussing glass in the K-20), the sharper my lenses become! If you are not getting good sharp images, manual focus ought to be on your check-off list before giving up on the lens.

For around 200 dollars?

If you can consider manual lenses, there would be a lot of options. For AF, I think the only game in town is the DA 35mm f/2.4.

If you can spend around 500, you could probably get both the 50 1.8 and the 21mm Limited in the used market - which I see would be your first option.
