Hello, PentaxWorld! And one equipment question.


after a few years, when I was only a reader of this forum, I decided to introduce myself.

I had started digital photography with Oly E-450 and i was amazed by using old manual lenses lik om 50 1.8 etc. Using old glasses was one of many reasons to step up to Pentax system. It is pleasure to read articles and post on this site, it has really helped me to learn.

So, I have one question. I have some spare money and i would like to upgrade my equipment.
I have k-5ii body and k-r as a backup. And oly pm-1 to play with my old om lenses

DA 18-55
DA 18-135 WR
DA 50-200 WR
DA 55-300 WR
DFA: 100 Macro WR
DA 35 2.4
Tamron 17-50 2.8
Allround Tamron 18-200

Pentacon 50/1.8
Panagor (Kiron) 135/2.8
noname CPC 28mm

I have also two flashlights.

What would you recomend to me? Im thinking about something wide, like 15 ltd.

The Sigma 10-20 zoom is a nice option too to cover the wide end and it's less expensive than the 15 ltd, especially if you get a used one. If you are looking for a compact wide lens than the 15 is the way to go since the 10-20 is much larger, but 10mm is fun to use and surprisingly there isn't a lot of distortion, which becomes negligable when zoomed out to about 12mm and beyond. There is a slower version and a f/3.5 version, but speed isn't really an issue when shooting that wide.

Welcome aboard!

As for upgrades, I would start with asking myself what I want to do that I can't do with what I have. The 15 ltd is a wonderful lens if you feel the need for something wider, unbeatable for e.g. landscapes and dramatic sunsets, but would be rather pointless if you wanted something good for portraits. (Ok, bad example - I would think the DFA 100 and the Pentacon and Panagor work well for portraits.)

Looking at what you have, my thoughts are
DA 18-135 + 55-300, great coverage, very flexible, really good for hiking, holidays
DFA 100, excellent for macro, good (but slow to focus) medium tele, ok for portraits if you have some space
DA 35, nice jack-of-all-trades, reasonably fast
Tamron 17-50, nice replacement for the kit, fast for a zoom
DA 18-55, 50-200, and maybe even Tamron 18-200 are pretty much redundant I think

The MFs are nice complementaries, should be good for low-light and creative shooting. For me they would both be a bit long for general walkabout business.

But again, look at where you think your current kit is limiting you in what you want to achieve. I could have saved myself a lot of money by doing just that

You have a really good kit. I wouldn't ad anything that doesn't have DA* of FA*or DA or FA ltd.The best ultra wide angle from my perspective is the Sigma 8-16 if you can find one.

The 18-135, DA 35 2.4, Tamron 17-50 and DFA 100 WR are all keepers from my perspective. Your weakest current lens is your 55-200. You could add a DA*200 2.8 and use the 18-135 to cover the low end. Except for Ultra wide, you're pretty much in an upgrade position rather than a new focal range... and with the 55-300, you could eventually want to upgrade that lens, but it's strong enough you probably want to make that your last upgrade.

To completely replace your 55-300 you'd need a DA*60-250 and DA*300 ƒ4 , at approx. $2500.
To replace your 18-135 you'd need a DA*16-50 and DA* 50-135 at approx. $2500.

From where you are... the 15 ltd looks like a steal to me. It ads utility without adding weight and gets you into an FL you don't currently have. So in terms of being able to just being thrown into the bag with what you already have, adding functionality without buying a new bag, or having to carry much more.. it's a really good call. I love my Sigma 8-16 but, these WA zooms are heavy, and they get left home to keep bag weight down.

Thanks to all for your replies

Yes, you nailed it.

I would keep kit lens for my k-r - when i will lend it to "nonphotographic" friend or child. But I thing that 55-200WR and tammy18-200 are redundant. I had bought it before 18-135 and 55-300 - and 55-200WR is almost new, because I'd bought it two month before 55-300WR was announced...
But used market here in Czech Republic is very small in Pentax - and prices that the biggest Czech used photo shop can offer me was near to nothing.

Same problem with buying used here. The are only two used WA, that i can find here, are Sigma AF 10-20/4-5,6 EX DC P for $425 and Pentax-DA 12-24/4 ED AL SMC in really heavy used condition for $745.

The cheapest WA zoom here is SIGMA 10-20/4-5.6 EX DC and is new for $645. And HD DA 15 mm F 4 ED AL Limited is new for $684. So prices are almost same.
Maybe a PENTAX 10-17/3,5-4,5 DA Fisheye ED for the same price is also worth to consider, but I'm not sure, that fisheye is for me.

I'm not thinking about upgrade my telephoto lens now, becouse I'm not shooting at these FL too much.

I'm also considering change my Tammy 17-50 2.8 for new Sigma 17-70 Contemporary, but i don't know, if the improvement worth the additional cost.

So when i want to rise to wide angle FL and my budget is maxed on $800 which would you recommend me?

I concur, you have a very flexible kit. The only thing I'd look at would be some wide-angle options. The Sigma 8-16 was mentions, and it's great but the price is climbing since it's been discontinued. The 10-17 fisheye is a lot of fun, and is highly regarded. I just got a DA21mm and am quite impressed, and it's my only pancake - of course the DA40 is a truly small pancake, but with your 35mm it's not really compelling.

You might find the 10-17 to be a fun lens. It's not for architecture... or anything with straight line that you want to keep straight, but it's good for people images.

The fisheye fun thing... Niagara Falls...

Used for a landscape, as opposed to a heavily corrected lens, people look natural even at the edge of the frame.

Even though it's called a fisheye, you can still do some serious landscape with it.

And it's half the size and weight of my Sigma 8-16.
As for the trading the Tamron 17-50 for the 17-70, for 20mm.. you're not getting much.

Welcome Jannis,
We were in your lovely country in April and the 15 is amazing with the architecture, landscapes, etc. Obviously not the most versatile butÖ..when the situation is right. Prague,Ljubljana,Prague, Kals-Matreien.

I pretty much agree with everybody. I have a Tamron 10-24 and that's a lot of fun, but I still want the 15 and 21. I would add the 15, although a zoom is more flexible, but you can move your feet too. I do have to admit that I take a lot of photos at 10-12mm, but that 15 is special.

Thanks to all for your advices.

Finally, i decided for DA 10-17, after some reading and searching - it would be a good 2in1 lens.

Now, its time to learn with such type of lense.

Thanks you.

If you have dogs, fisheyes are always fun - if they don't mind a camera stuck in their face or leave nose juice on the front element....
Also, it's really easy to get yourself in the picture...
