Taking photos outdoors like a 50mm 1.8 is my plan while not necessarily macro, and not portrait. A go to lens is what I have in mind. Is this a reasonable expectation?
Asked by: Alex
I don't really understand your question but if you're looking for a 50mm lens, this is not it. This is a 100mm lens that can be used on a full frame camera. Using it on a crop sensor camera would yield an equivalent 160mm. This lens, along with being a macro, may very well be used for portraiture.

No, it is not. The Pentax 645D uses the PENTAX 645AF2 bayonet mount, the Pentax smc Pentax-D FA 100mm f/2.8 WR Macro Lens is designed for the Pentax K-mount. The Pentax 90mm f/2.8 D FA 645 Macro ED AW SR Lens, B&H # PE9028645, and the Pentax smc FA 645 120mm f/4 Macro Lens, B&H # PE12040MC, are the macro lenses designed for use on the PENTAX 645AF2 bayonet mount. http://bhpho.to/1yIAMq4

I'm noticing there is no aperture ring. I have a pentax k1000 and I'm wondering how I could change the aperture with this lens. That option isn't available on older film cameras of course. Any solutions?
Asked by: Patrick
For those wondering the same, I found this alternative. It is on B&Hs site. "Rokinon 100mm f/2.8 Macro Lens for Pentax K. Has good reviews for other mounts, I'm assuming the same for the K-mount.

question

ok so if I have the DA*50-135 2.8 that I'm real happy with on my K20D, other than the macro feature do I gain anything else putting this on my K1?
Asked by: Lawrence
Your sensor determines the crop factor, not the lens. So the 100 mm would give the equivalent of 150, just as your 50-135 provides the field of view for about a 75-210. Therefore as a telephoto it would certainly overlap. But the macro feature is the main reason to own this lens as it gives super close focus and 1:1 enlargement (life size) at the sensor. Different applications and I can recommend owning both for your K-20D. If you elect to go full frame body later, this macro lens will be a keeper, but the zoom will not cover the full frame.
