Here's some stuff at the far cheaper (under $90) spectrum of the 200mm K Mount Lens choices
THE PRIME RMC Tokina II 200mm f3.5
+Cheap
+relatively fast aperture, clicky aperture ring
+smooth focus
+light
+pretty sharp (sharpest at f11)
-some minor green fringing, almost gone by 5.6
-slightly soft wide open
THE ZOOMS TOU/FIVE STAR MC AUTO MACRO ZOOM MC 70-200mm f4
+some macro ability
+smooth focus ring
-soft..ok if you focus..really well
-green fringing (gone by f8)
-some purple fringing
-sharpest f16?
-aperture ring a bit hard to use. tightly sandwiched between focus ring and body.
-blob of blue reflection at barely noticeable at f16..gets kinda bad at f32. (sensor reflections?)
-Yes, this is one of those the dreaded non-SMC Takumar/CPC/Cosmicar 70-200 cheapo SMC A70-210/4 clone zooms
Pro Rokinon MC AUTO ZOOM 80-200mm f4.5
+cheap..like $5 cheap
+light
-not what its name suggests.
-soft
-green fringing (gone by f8)
-sharpest at f16?
-sensor reflection f16-f32
Vivitar 75-205mm f3.8 MC Macro Focusing Zoom (Kiron made)
+Smooth focus
+Quality feel, probably related to the S1 70-210
+noticeably sharper wide open than the others
+crispy by f5.6..maybe a tad better at f8..I can't tell
+some macro
+/- heavy and bulky..depends on your style
-minor green fringing (gone by f8)
-sensor reflection f16 to f22
Tokina SD 70-210 f4-5.6
+very light and compact
+intuitive zoom (compact = 70mm, extended = 210mm)
+no sensor reflections!
+/- some metal and some plastic
+/-pretty good by f8...sharpest at f16?
-a bit soft wide open
-some green fringing..I thought this was an "SD" lens...(gone by f5.6)
-some purple fringing...so much for the "SD" label...(very minor at f11-16, finished by f22)
(Photos will be up later tomorrow, sry my internet sucks. haha)
