Hi, Carlos. > Probably the M 85 mm. f:2 is an excellent choice for portraits.
The M 85/2 is a pretty good portrait lens, despite its unpretentious seeming design, and is the most economical Pentax K-mount 85. > The lens I use the most for portraits is a K 85 mm. 1.8 and I love > it. [and] The only problem about the K 85 mm. 1.8 is that it's > scarce nowadays and consequently somewhat expensive, if you happen > to find one in good condition. The K 85/1.8 is a really fine lens for portraits, but has gotten ~very~ expensive to obtain. In the field of expensive 85's, it's a "best buy"... > I also have a K 105 mm. 2.8, but I also think it is a bit long > for that kind of work. The K 105/2.8 is fine, if it's not too long for the situation, and if you watch out for its bokeh. Actually, I usually wouldn't find 105mm too long, and I often use a 135mm lens for portraits. (The limiting factor is often the available space - the 135mm FL gets might long feeling if the room is small. > Fred has a comparison test in his web page about several 85 mm. > Pentax lenses.

(I also like suing the Tokina AT-X 60-120/2.8 when a zoom fits the situation...) Fred
