Pentax 100mm macro WR vs Non-WR

Been shopping around for a good macro, and ive noticed something odd. The smc PENTAX D FA MACRO 100mm F2.8 WR is less expensive than the NON-WR smc PENTAX D FA 100mm F2.8 Macro.

Anyone know why this is?

The non-WR macro has been discontinued for a while, and I believe there's currently a rebate on the WR version, so a store still listing the old lens at MAP pricing may actually end up charging more for it.

If given a choice and equal cost, I would choose the WR version. Big difference is the WR and the rounded aperture blades, which can produce a little nicer bokeh. Otherwise they're the same lens.

It will depend on the TC, but a TC without any external optical element will work. Wether images will be good or not is another matter.

If prices are similar, I'd go with the WR in a hearbeat. Better made, smaller, metal, WR, a much better choice.

That's a good point - the old version has an aperture ring, so it's easier to use with extension tubes or TCs without contacts.

I own the D FA 100, pre WR, and my impression from image examples is that the WR is better -- mostly in the area of CA/PF. Of course, there's also the WR. If I were in the market for a 100mm dedicated Macro, the WR version would be a no brainer.

I originally chose the D FA for its weight since I like to shoot macro handheld with flash, and the WR version is actually smaller and lighter.

Any macro lens can be used with a TC for added magnification. TCs usually allow slightly closer Minimum Focusing Distances, so the magnification increase can be slightly greater than that stated on the TC (for example, the 1.7x AFA on a 1:1 dedicated macro lens results in about a 1.9:1 mag ratio). Whether the IQ will be satisfactory is up to the quality of the TC, and the skill/technique of the photographer. Any faults in the lens will be magnified by the TC, and any faults in the optics of the TC will probably be obvious. In addition to the mag ratio, the lens will lose effective max aperture directly proportional to the magnification increase. Greater than 1:1 macro photography becomes exponentially more difficult as the magnification increases. Advantages that can be gained with a TC is that with the increased effective FL, one can shoot at 1:1 at a longer working distance. This gives deeper DOF, is possibly less intimidating to live subjects, and gives you a shallower angle for a camera mounted flash.
