This is not a question - more a mini review of the Kiron 105mm f/2.8 macro MF lens with Nikon mount. I had previously shot with the Nikkor 60mm f/2.8 AF D macro lens - shooting mainly botanical close ups and occasional insects. I required a tighter field of view but could not afford the current Nikkor 105mm VR macro lens and was losing bidder twice on ebay auctions of the older manual focus Nikkor 105mm macro lens. I happended to stumble upon this Kiron model (on eBay as well) and won it at auction for (what I happen to believe is) a miserly AU $179.50! The Kiron 105mm macro lens is circa 1980's , manufactured by Kino precision in Japan who also manufactured lenses with the Vivitar brand on them. The unit I purchased is in excellent condition and is quite a revelation to me at least! As I shot vitually always in manual focus mode 100% with my prev. 60mm macro Nikkor the lack of AF on this lens is not missed by me for the type of macro work I do. In fact, this has to be the very best lens I've used for ease of manual focusing. This lens has a beautiful slowly graduated barrel twist action which rotates a full 1 and 3/4 turns to run through it's reproduction ratio begining at 1:10 winding through to 1:1. The manually adjustable aperture ring allows adjustment of settings from f/2.8 max to f/32 min. When coupled to my D200 and the necessary on board menu non-CPU settings dialed into the D 200, this lens meters just fine in Aperture/Shutter and Manual modes making this old beauty a geniune pleasure to hook up and shoot with. The Kiron 105mm macro lens is razor sharp from left frame to right and can deliver some good bokeh given some distant backdrop to bounce light off. I understand that the older non-Ai and Ai Nikkor lens range will perform similarly with the D200. I can recommend to any D200 shooter who is hamstrung with budget constraints or just likes good things in small (older) packages to seriously consider searching for the older manual focus lens range which are so compatible with the D200 - my old Kiron is a gem and has boosted my appreciation and enjoyment of photography (and my budget) no end!
