Originally posted by catpig I am a great pentax lover, and I am determined to stick with Pentax. My current kit is an old k100 D, with a couple of old manual prime lenses (a 135 and a 400), and a sigma 70-300 APO macro. I have recently rediscovered my enthusiasm for photography, and having in the past got some cracking shots with my range of lenses ( I maily love wildlife photography), I have been looking into a replacememt for my old body, that is going to give me even better image quality. So, firstly, does anyone have any idea how my lenses are likely to perform with a K-30? It looks like it would give me far more freedom, but lots more to learn! and secondly, I need to replace my 18-55 (unfortunately dropped), but have been thinking about getting a longer zoom, maybe 18-135 or 18-200. My budget is not huge, but I do want a good kit without spending more than is really necessary. Any suggestions? Thanks!
Well first of all let me explain my own experience - I started my Pentax career with a K100D which my son now hs, then went to the K20D then K and now K30 as a back up to the K5. The K30 has fpcus peaking which is a grea boon for old manual lenses; I regularly use a SMC-A 50mm f1.7 and a fully manual 55mm f1.8. Also have used 28mm and 24mm SIgma lenses (A setting) 105mm Adaptall lens, SMC-M 200mm , all work well on the K30 and the extra resolution of the 16mp cmos sensor vx the 6mp CCD in the K100 is onvious
I also use the 18-135 DA WR with my K5 and K30, I find it a convenient lens with excellent focussing and sharpness absolutely fine for 85% of shots. It is quite expensive though, I got an unboxed one split form a kit, would be worth looking out for similar or mybe an ex-demo version. The IQ to my eye is quite a lot better than the 18-55 ( I have a MK1 from my K100D and a WR from my K20, but very rarely use them now)
You will find that the extra resolutuin and good DR/noise characteristics of the K30 mean you can crop quite heavily from the 135 end of the zoom and still get pretty reasonable images; I certainly value the WR of the 18-135 and would choose this over a non-wr zomm with a longer reach.
Hope these thoughts help
