Try the lens review area -

Pentax DA Prime Lenses - Reviews and Specifications - SLR and Interchangeable Lenses - Pentax Lens Reviews & Lens Database
Pentax FA Prime Lenses - Reviews and Specifications - SLR and Interchangeable Lenses - Pentax Lens Reviews & Lens Database

etc.

Personally I like the DA 15mm Limited, DA 35mm Macro Limited, FA 31mm Limited, DFA 100mm Macro, and DA* 300mm.

In zooms both the 55-300mm and 60-250mm are nice. The Tamron 70-200 is an underappreciated lens - the biggest knock against it is the 'slow' focusing speed - when evaluating it on a Canon or Nikon. On Pentax it focuses quite fast, faster than the 60-250mm (which is only f/4).

I've stayed away from the 16-50mm, due to cost, size, weight, and reliability concerns. Recently the cost went through the roof on some lenses, particularly the 16-50, so I would advise against it.

Bonjour,

I'd suggest a DA 35mm f2.4 AL ... the "plastic wonder". Great IQ and super bang for the buck lens ... this 35 shoots like a "50" with the K-5's crop ...

Also, the D FA 100mm f2.8 WR is great ... have both of these, otherwise I have a lot of Pentax legacy glass and Tamron Adaptall-2 ... J

How much money you have to spend on lenses!?

Pentax has several ranges of lenses.

In primes the word 'Limited' after the name indicates the best range. These come in both FA (31mm, 43mm, 77mm) and DA (15mm, 21mm, 35mm, 40mm, 70mm) models. The DFA 100mm WR is similar in build to the Limiteds and despite not having that in the name is usually lumped in that group.

In zooms the best current models are the DA*16-50, DA*50-135 and DA*60-250. These are all weather sealed and well regarded. Generally anything that has '*' in the name indicates top of the range. There is also a complete FA* range but they are discontinued so only available used.

Other companies such as Sigma also make lenses for Pentax and in some cases their equivalent model is considered as good or better than Pentax at less cost.

Pentax makes very few lenses that are not of good optical quality, although the build quality varies with cost. As noted above check the lens database for user reviews. It really comes down to how much you want to spend.

People are putting the horse before the cart in my opinion.
Did you get the 18-55 kit lens? If so, what is it about that lens that makes you want to spend money on a different lens (something faster, more reach, wider etc)?

What is it you want to photograph?
Will you be shooting sports or stationary objects?
Will you be shooting in really poor lit places?
Will you be shooting in the rain or snow or in other situations which require weather sealing?

Oh, and of course, how much money are you willing to spend?

What's your budget? IF I had my way I would get the 16-50, 35/2.4, 70, and the 300 (just because I like to shoot birds!). Just my 2 1/2 cents.

Thank you guys for your kind replies. Thanks to those who suggested me some links and lens models. To others:
I will mostly take portraits, landscapes, indoor/low light photographs, birds and occasionally wedding pictures. Don't need weather sealing lenses.
For now my budget is £350-£500.
I have recently bought Pentax SMC DA 40mm F2.8 XS (2012 model)... if anybody has used it, what do you think about this lens. Do I still need a f1.4/f1.7 lens for portraits and low light photography? For wedding pictures do I must need auto focus lenses?

Portraits: Generally use lenses from 50mm -> 135mm. The 50mm's can be inexpensive, there's a DA 50mm that just came out that is inexpensive ~$200 and has good reviews. I've never used it. The longer, faster glass is much more expensive.

Landscapes: Generally considered to be wider angle lenses. The 35mm F/2.4 is a nice lens but if I only had one lens I'd go for something wider.

Birds: Need long lenses. Fast glass helps AF. The 55-300mm is a good less-expensive option. The Tamron 70-200mm is much more expensive but could double for some wedding stuff (but is also a bit too long for a lot of indoor work).

Nothing 'requires' AF, but it certainly helps. Many people shoot weddings with F/2.8 zooms, so the F-stop isn't necessarily what will kill you.

If I were you I'd probably try to pick up a cheap 50mm and see if I liked it (some older manual ones are $30). What lenses do you have now?

In three lenses:
Pentax 12-24
Tamron 28-75
Tamron 70-200

But for birds...Sigma 500, or a much cheaper sigma xx/xxx-500 zoom.

DA Limiteds may have a better FL selection than the FA Limiteds if you want primes.

Just about any 70+mm macro lens is good.

The 10-17 fisheye is fun.

I have Pentax SMC DA 40mm F2.8 XS, old Pentax M 80-200mm zoom, and Sigma AF 28-80mm macro(? i would say good close up). The last 2 lenses i bought for cheap to try different types of lenses. Full manual Pentax M 80-200mm helping me to learn how to control everything manually. So now i have some sort of ideas about manual lens, zoom lens, different focal lengths, and macro(?) lens. What do you think about Pentax SMC DA 40mm F2.8 XS? I like it as it is very sharp and boke is good. But af sometimes works slow. I am thinking to get a f1.4/1.7. As you suggested i think i should try some old lenses, like Pentax m 50mm f1.7.

You can't go wrong with a MF 50/1.7. I absolutely love mine, especially at f/2.8!
