Thanks... And I need some help on lens designations...
The Pentax is a remarkable piece of equipment, and I am staggered by the images it produces, even of rather prosaic subjects. I am feeling immense lens envy, and so far do not feel that it is any huge task to carry the thing around. I may feel differently when I decide how much to plunk down for a zoom lens. I can not, honestly, discern the difference between lenses. There is a 33-55mm lens offered around eBay and descibed thusly:
PENTAX-FA-645-ZOOM-33-55mm-F4-5-AL-MediumFormat-645d-645Z
or:
Pentax SMC FA 645 645Z 33-55mm F/4.5 AL Lens
These run $1000 or less.
I do not understand the lens designations, and what I would expect from this lens in terms of quality? What is the designation of the highest-quality zoom/AF lens I would normally buy in the wide angle to "base" focal length range? All manufacturers make this hard to sort out, Pentax seems to have made it absolutely impossible. I see what appears to be an extremely high quality zoom for $800, the seemingly identical lens for $2,000, and then an
ED DA 28-45 that runs from $3-4k - and just under that a "
DA 55-300
ED zoom 55-300 for $300?? So, his is totally confusing. Can anyone help me sort this out? The Pentax website is no help.
Should I start a new thread or maybe there is one already???
