Originally posted by ScooterMaxi Jim Welcome back to Pentax. If budget and weight are not obstacles, then the higher end DA star lenses are the way to go. The pairing of the 16-50 and 50-260 will work very well. Frankly, between the 18-135 and the 18-270 there is so little difference in overall IQ, you can go with either one. Frankly, the 18-135 is somewhat underwhelming in this category, and the 18-270 is pretty good for what it is. Not saying that the 18-135 is as marginal as a 15-to-1, but the difference isn't as great as you'd expect. If your heart is set on the 18-135 length as a main lens, Nikon is the better way to go.
I suspect Jot is worried about weight and size. Then the 18-135 and 55-300 WRs are the best bets. You want to avoid using the 18-135 beyond about 75mm (it really is a bad lens long), so the pairing of these consumer lenses is pretty good.
If you are shooting 1600 ISO or above exclusively in AF half the time without any flash, then the K05IIs is your better choice. Shooting at normal ISO, shooting some flash, want to use manual focus, or understand that Live View is a valuable tool on occasion, then the K-3 is the far-better choice.
ScooterMaxi, that is a good review. Actually I am Pentax since 90's with film cameras, and I really enjoy it.
My point is: Fuji XE1 with Fujia 35mm f1.4, 18mm f2.0, and also Zeiss Jena 50mm f2.8 with adaptor gives me a great tool for indoors. But I feel the lack of outdoor shots without any concern on the weather, and that is where Pentax is king. So I won't buy glass that competes with Fuji's what I need is a supplement of my existing glass for outdoor. Personally I hate any kind of flash, and in my retired K30 I used to use ISO 1600 or even 3200 in BW straight from the camera and only occasionally used a TTL /Manual flash I had. The tricky point now is: K5 IIs or K3, and lens18-135mm or 55-300mm or 16-85mm. Being K3 an evolution, could it not fit all K5 IIs set of uses?
Something I forgot - edited - I always print, and hate post-processing that interferes too much on the shot . That is my final objective.
Thanks guys!
