hey guys. i just got my grandfathers old Pentax ME Super with a bunch of accessories, I took a photo class in high school but it mainly focused on the darkroom work and composition, but not so much on using the equipment to its full potential, especially lenses. we stuck with the stock camera lenses the whole class. what are good ways to learn what to use and how to use it in various situations with the equipment i have? here's a list of everything i got: Pentax ME Super Lenses: SMC Pentax-M 1:2 50mm SMC Pentax-M 1:3.5 135mm TOU/FIVE STAR MC AUTO MACRO ZOOM 1:4 70-200mm Ambico V-3100 Wide Angle 0.5X* Home-made pinhole lens using the dust cover =] Filters: Pentax L39(UV) Toyo Optics Polarizer Tamron SKY Etcetera: 2X Extension tube Cable Release (1ft long) AF 200S Flash Unit *This lens attaches to whichever lens im using via a screw on adapter, almost like a filter. it doesn't fit my macro zoom lens, but then again what would be the point? i would just use either my 50mm or 135 mm lens in that situation right? Also, with the macro zoom lens, i have trouble focusing precisely because the bottom of the 'split-image' focus circle is completely black unless im pointing the cam straight at a light bulb or something Thanks for all your guy's help in advance!
