DavidB77's current gear

Pentax K-3 II
HD Pentax DA AF 1.4X AW Rear Converter
HD Pentax-DA* 11-18mm F2.8
Very good quality when you can achieve perfect focus. However, it is pure luck to get perfect focus using the converter with 300mm. Not very useful I would say.
Pentax smc DA 35mm F2.4 AL
Pentax smc DA 50mm F1.8
Pentax smc DA 70mm F2.4 AL Limited
Not very good wide open, but excellent IQ when you stop down for landscapes. I don't know why but sometime, center is soft (out of focus) while edges are razor sharp which is very anoying. May be its my copy, or it would have 5 stars, especially for the price. I miss QuickShift compared to Limited lens.
My favorite lens! Perfect for portrait and landscapes. 5 stars!
Pentax smc DA* 300mm F4.0 ED (IF) SDM
Focus a little slow and not precise, but very good IQ wide open and accros the frame. I love it, very recommended! Would be an instant buy if Pentax renew this lens with a better motor.

Poor sharpness at edge. Cannot stitch panoramic with this lens.
Very good lens! Very good sharpness edge to edge. I would like the same with WR.
Nice first 300mm lens to play with, but quality is only entry level.

Returned, decentered, soft right side.
1st copy) well centered but bad edges in 18-22mm range 2nd copy) decentered: soft left < 24mm, soft right > 24mm at every apertures 3rd copy) decentered: soft right at every focal lengths and apertures
Too bad, the lens is perfect on the paper, but... Very strong field curvature. Cannot get the entire scene into focus. Cannot stitch panoramic with this lens.
HD Pentax DA 16-85mm F3.5-5.6 ED DC WR
Soft corners (or very bad copy) at every aperture, not recommended for landscape work.
