These are the lenses I have:

Manual: 50mm f/1.7
A: 35-105 f/3.6
Kiron 80-200 f/ something, I don't use it
28mm f/2.8
FA 80-320 f/4.5-5.6
DA 18-55 WR

So here is the question: If you had only these lenses, what would you buy next to expand the range or to upgrade in quality? And base this off or what you like to shoot: this isn't for me.
I'm just interested in what directions people would go with this set.

[rod_grant]

My first buy would be DA35 Macro Limited.
This would cover macro which you don't have and would put a premium 'normal' focal length lens into the collection.

D FA 100mm F2.8 for macro

[drypenn]

A mint K 50mm/1.2

[hjoseph7]

20-40mm f2.8-4. I just love the way that lens looks !

[SpecialK]

Something wide.

[jbondo]

K 50mm/1.2 or a Fisheye

Looking at your lenses, you have several zoom and only 2 primes. Thus i would look into a new prime lens.

*AF or MF?
If you are happy with MF, you would like to go wider and shorter than 50 and 28 mm: for example, a 77-100mm, or a 15-mm. My suggestion would be DA15mm Ltd and FA77mm Ltd

If you want to go to AF, I would suggest to consider 50-85mm, where there is a good range of option. A suggestion could be the DA*55mm.


But I also depend what you like to shoot: landscape, portrait, birds in flight....

My 5 cents.

Hard to say without knowing what you use and what you wish you had. You very wide angle. You also have some lenses that you might want updated replacements for, the fa 80-320 for instance might be nice to replace with the da 55-300.

Depending on mood a super wide angle zoom 10-20,12-24 etc. might be perfect on paper, but it only matters if you feel the need.

My first buy would be DA35 Macro Limited.

I second that.

FA 31/1.8... Life's too short to dance with an ugly partner. Dump the rest of your lens collection. Your K30 paired to the 31 will keep things simple and position you to pursue excellence for the rest of your photographic life.


..my 2 cents... M

"Primes!" Personally I would start with a FA or one of the DFA 100 2.8 macros, followed by something on the wide end. More than likely a DA15 before a 21.

[acoufap]

As long as there are no FF high quality Lens options and a Pentax FF camera my priorities are

1. HD DA15
2. HD DA 20-40
3. DA300 or DA 60-250 - HD updated Versions as soon as available

So expand "my" range and upgrade in quality

[schnitzer79]

if you are into photography and youre thinking of taking it more seriously then at some point you will want to upgrade to better lenses. so why not sell a few first and start off by building a good base from there.
if i were you id only keep the M50 1.7 and sell the rest. id buy the 18-135 first to get to know all the focal lengths and what I would use most, and then go on from there. but a good order would be something like this :

18-135
15mm ltd
35mm ltd macro
77mm ltd

if you have the budget of course
personally, ive acquired the first two.i might have to go straight for the 77mm next

You already have a "Stack of Primes" in the 35-105. If yours is sharp, you don't mind the weight and manual focus, it has its own "look" to it.
The traditional set is 28mm, 50mm, 135mm if you are shooting with a film camera; you still need the 135mm.
For APSC you want something wider than 28. Perhaps one of the Limiteds, DA-15 or DA-21.
