I'm currently rocking a Pentax K-7 and just obtained a bucket of limited primes thanks to an eBay auction. I can't afford to keep this stable of lenses, so I am looking to consolidate my kit.

Got:
- Sigma 10-20mm
- DA15mm limited
- DA16-45mm
- DA35mm macro limited
- DA40mm limited
- FA43mm limited
- FA50mm
- DA70mm limited
- M 50mm f1.9

Want:
70-200mm f2.8

And here's what I was thinking...

Keep:
- Sigma 10-20mm (excellent for wide angle, dramatic landscapes)
- DA35mm macro limited (excellent "normal" lens with macro capabilities)

Sell:
- DA15mm (Don't need when I have the 10-20)
- DA16-45mm (currently selling on eBay)
- FA50mm (I find the focal length a little awkward on crop)
- M 50mm f1.9 (don't need, only kept for reversing on extension tubes)

Undecided:
Having a hard time deciding what to keep out of the following:
- DA40mm (sharp, awesome size...but too similar to 35mm/43mm?)
- DA43mm (image rendition and colours, but too similar to 40mm?)
- DA70mm (will I want to keep this when I have a 70-200mm?)

Buy
- 70-200mm f2.8 (not sure Tamron/Sigma - looking for suggestions)

Comments and opinions apprecaited

I'm interested in the 16-45mm lens. How much do you want for it?

Will you want DA70 when you'll have 70-200 zoom? Put DA70 next to any zoom and it'll help you decide

For the rest: 10-20 vs 15 seems you made your choice and you prefer flexibility of the zoom over size and flare resistance of the prime.
35mm is your call.
40 vs 43 is debate ever since the DA40 was made. Personally, I sold 40 to keep 43 and I think 43 gives you bit more of a gap between your lenses and I prefer it's rendering quite a bt.. Trying to be objective: 40 is smaller, lighter, faster AF, better CA control, worse PF, more even sharpness. Sharper at f8 and after... 43 has slower AF, better MF, worse CA, better PF, is stop faster, is sharper at any f stop up to f8, has bigger difference between corner and center sharpness, is bigger (noticeably with hood on). Ultimately it boils down to this: do you need/want f1.9? Good luck choosing

I would definitely keep the DA70. You do not always want to carry a 70-200 around for just the 70mm focal length.

From those lenses the combo 10-20, 35 and 70 would make a nice kit for 'normal' work for me. The 70-200 will complement it nicely for tele needs.

If you need a gap filler between 35 and 70 and you don't like the 50mm focal length, keep the FA43Ltd as well (it's a bit more in between and, after all, it's a FA limited ).

Sigma 10-20mm
DA35mm macro limited
FA43mm limited
DA70mm limited
Tamron 70-200mm f2.8 (you may want to consider the Pentax DA*60-250/f4 - especially if you later get a K5 or Kr for the high ISOs).

The Da 70 Ltd is s completely different animal to any 70-200 zoom and I'd definitely keep it for short telephoto / events / portraits etc.

That would give you a great kit just missing the DA* 300 !

Axl - the 43 Ltd may be bigger than the 40 ...but it's still tiny (or feels that way to me)

I never said it's a big lens. I love the size of it. But I used to have DA40 and have to say that with hoods on the 43 is notably bigger. But you are right. It's still a small lens!

I would prefer the 15, but you like the 10-20, so you're set there.

Agree with keeping the DA 35
I would also keep the DA 70

As much as I don't love my FA 50, the fast aperture is handy sometimes.

I see no reason to keep 40 & 43 if you're keeping the 35.

[Intric8]

The reason why I've stated that I'd prefer the 10-20mm > DA15mm is that shorter focal length is more useful for dramatic landscapes (particularly seascapes). Plus, I have recently purchased the cokin p series kit with some GND filters.

Convince me why the DA15mm is more useful and I may consider it.

I like the flexibility of the DA35 macro - I can use it as a general purpose walk about lens with the possibility of macro performance.

The FA43 is probably taking my fancy more than the DA40. The DA40 is one sexy, small beast, but I think I prefer the extra stop and the way the FA43 renders OOF areas.

DA70mm will probably keep. The FA50mm is definitely going, as I mentioned I find the 50mm focal length on crop body a little awkward at times.

Any suggestions on the 70-200mm? Which is generally accepted as the better lens; the Sigma or the Tamron?

Only re: Sigma/Tamron 70-200 - the choice is yours - both have strengths and weakensses.
I prefer the Tamron for my own reasons, particularly the excellent IQ, which I have discussed in these threads:
