Best Lenses to Complete Move to Pentax

As you may know, I recently bought into Pentax with the K5iis, 35/2.4, 50/1.7, and 17-70/4, and I'm looking for advice on how to fill the holes. I prefer shooting short zooms (2-4x) but I also like the prime way of life. I will need a macro (can be mf), portrait lens (stuck between the 77mm and 70-200 or 50-135). I have already decided on the 12-24 fow my uwa needs, but would you advise for a 77mm or the versatility of a zoom. Also, do you think the 31mm f1.8 should replace my 35/2.4? People are saying that it is superb and special but the f2.4 is really, really sharp already. For the macro, would a 50mm, 70mm, 100mm, or 150mm be more versatile, I do flower shots and the occasional bug shot. I was thinking either the 50 or 70, which would go well with the range of my 17-70 and bridge the 17-70 with the portrait zoom, or the 150mm which would fall at the end of the 50-135. Also, for a tele lens for airshows and occasional wildlife, can you recommend a mf lens with iq that is comparable to the Sigma 150-500? I usually use mf on my Sony and Tamron 200-500 anyway, so I might save with a mf lens, but I need the image quality to be there. Going by my current thinking here's a plausible lineup

12-24
17-70
31 limited or 35 f2 ( sounds very convincing)
70-200 or 50-135
150 macro
Sigma 150-500

That sounds like a great lineup (go for the 70-200mm, as it'll work well together with the 17-70mm).

Only thing is that there's no 150mm macro for Pentax (only Canon/Nikon) from Sigma.

So would you recommend the 100mm, 50, or 70?

I'd suggest that, at the medium-narrow end of things, you try the 50-135 first, and see how it influences your style. You may decide that the FA77 is a bit redundant (I have both, and no intention of letting go of either, but I bought the 77 long before the 50-135).

At the other end of things, a lot of people here like the DA12-24. I went for the Sigma 10-20, and haven't regretted it, so I'd recommend looking at one of those before you decide.

eh, don't really like Sigma in general and I dont need 10 at the wide, rather have less distortions.
Also I've decided at that price i cant justify the 77 over a 70-200, which is much more versatile.

Macros for K series

If you're shooting towards the 1:2 end or closer, you might prefer the longer working distance of the 100 over the 50. Not to diss the Pentax-M 50 f/4, mind you, it is an incredible little lens IMHO. But for example I just picked up the O-Photo clone of the Rayflash ring adapter for doing macro work, and found that if I shoot in the 1:4-1:2 range, the subject is too close to be fully illuminated by the ring. (There's some mod work in my future, I suspect.)

If you've got the money, people absolutely rave about the 100 WR -- autofocus* and weather-resistance, how could you go wrong? The M series 100 f/4 is also exceedingly well thought of, but spendy compared to the 50.

(*Yes, I know that autofocus can be a hindrance rather than a help in macro work unless you're working with flat things or shooting at f/gazillion.)

ok, i will consider the 100mm non-wr and the f4 manual. Honestly the 100mm f4 is so cheap I could just resell it if I feel the need for af.
audiobomber, will a 300mmf4 with a 1.4x tc match the iq of the Sigma 150-500 at equiv. fl? Also what tc would you recommend?

If you travel a bit to do your pictures, you'll start to appreciate the Limiteds...I really like the FA77 for portraits, but the DA70 is a lot more bang for the buck. Just last week I decided to travel with both the DA70 and the Tokina 80-200 f/2.8...the Tokina is excellent in quality and optics, so is the versatility of a zoom, but honestly, I ended up using my DA70 most of the time because I got tired of hand holding all that weight and walking around. Thankfully I had the freedom of "zooming with the feet" in the environment I was shooting at.

I guess the decision between using primes or zooms will depend on you do your portraits (indoors, outdoors, studio, environmental, etc.) I've also had the Tamron 70-200 2.8, and it's also excellent glass (irrespective of price).

For macro, I would suggest the Tamron 90 f/2.8...it's sharp as hell and the price is very affordable. This is my most used lens for plants and animals.

Welcome to PF and Pentax.

If you are after image quality (IQ), you should not miss the prime lenses and there are many great one. In particular:
- the FA Limited series, especially the FA31 mm and FA 77mm IMHO, both very highly regarded,
- the DA Limited series with their pancake design are great - I have the DA40mm xs and the thin desing is amazing

Based upon your present lenses and if you are after IQ, the FA31mm and FA77mm are a must.

My 5 cents....

Yes, I didn't consider the tamron, I got wonderful macros with it on my sony, hopefully the price has kept falling.
I think I may just go for the 77/70 limited and if I feel the need for the 70-200 range pick up a 55-300? What do you guys think

By the way, THe A* 300 seems to be much more expensive, in the bigma price range, whereas the M* seems to get better reviews here at pf and I couldn't care less about manual aperture/stop dpwn metering

Also, can anyone tell me about the A* 200mm macro? At 1.5 grand seems WAY overpriced, with the sharpness of current macros, how does it compare with the 100mm pentax and 90mm tmron?
