I am still very much a noob to this great hobby but I have been struck with LBA and have purchased within the last few months seven lenses for my k5 II:
Pentax M28 f/3.5
Pentax M50 f/1.7
Pentax M50 f/2 (package deal with the 1.7)
Pentax M75 - 150 f/3.5 zoom
Tamron SP Di 90 f/2.8 macro (I am really looking forward to trying this when the snow finally melts)
Pentax M135 f/3.5
Vivitar p/K,M 2x teleconverter/macro (just for the heck of it and the price was right at $20)
These are in addition to the Pentax FA 28 - 80 f/3.5 - 5.6 and Pentax FA 80 - 320 f/4.5 - 5.6 zooms that I already had from a previous camera (MZ-7).
Would it be worth buying a Pentax 16 - 45 f/4 zoom? Would the M28 be wide enough for landscape? Am I spinning out of control?
The price isn't too bad at $180 Cad for the lens, a UV filter and a Hoya polarizer but I was wondering if I was already pretty well covered for wider shots. I know that this is a subjective question but I was wondering what other people thought.
