As I speak, there is a brand new K-R kit in the mail for me. This one includes the regular l8-55 zoom lens. However, I opted to buy the DA P-55-300 mm F4-5.8 ED lens which was more expensive than the DA-L-55-300 mm F4-5.8 ED lens. I also purchased the 35 mm F2.4 AL lens as my only prime. Perhaps that was a mistake. You tell me.
The purpose for the 35 will be for my project. That project will consist of taking stills of garden tractors posed mainly in outdoor settings but quite possibly indoors as well. Further along, I want to get into what additional equipment I should have but for now, I want to focus on the lens issue....... pun intended. Pentax also offers the DA - 35 mm F-2.8 macro limited lens. The question in my mind is whether or not I should have chosen this lens instead. Being relatively new to DSLR's and the jargon that goes with them, I don't know what "Limited" means when it applies to lenses. My understanding of "macro" is that it allows the user to focus on small objects at very short distances. For my purposes, a six foot long by 3 foot tall garden tractor does not qualify as a small object in need of a macro lens. So am I missing anything here? Should I have opted to jump to the 50 mm with the lower F-stop rating instead?
I also purchase Hoya UV fliters for the two zoom lenses but the store did not have one in 49 mm for the 35 mil lens. I went for the Super multi-coat line instead of the low end or the PRO level. So..... if I can please have some feedback on those issues to begin with, I'd be most appreciative.
The APS-C cropped sensors are now so good, that there is not much in it except for the ever so slightly better IQ and shallower Depth of Focus control on the FF using equivalent lens. It sound like your choice of APS-C is a reasoned and sound one.
The DA35f/2.4 is a great little prime, and should do nicely for your chosen subject as razer thin DOF control is unlikely part of your need, and doesn’t sound like macro is needed. The 35mm on the 1.5x cropped sensor is close to normal eye perspective, so this might be good for your work. The limited lens are just very good lens (build and image quality). The DA35f/2.4 is a cheap build, but with very good IQ.
The choice of the DA18-55 and DA55-300 should serve you well for general photography, and the DA55-300 is actually a very good lens in that zoom range. The DA-L versions are optically the same, but lack the quick-shift focus clutch (very handy), hood, and have plastic mounts. So your choice is a sound one.
On the UV filter angle, the general view is, if you do it, get good filters, but lots will recommend not to bother. I recently removed the UV element on a 170-500mm lens, and discovered that the IQ improved significantly. So check the results.
Good luck, and enjoy.
