Pentax D FA 645 90mm f/2.8 Macro ED AW SR Reviews

No manual control for aperture

By Theuns

Aperture is only controlled electronically from the camera. So forget about using extension rings or a helicoid extension. Fantastic lens otherwise, but it is limited in use for macro work. The old 120mm with aperture ring offers both camera and manual control and you can push the magnification from 0.5 to 1.0 with extension rings.

Best Lens in the basket

The more I use this lens, the more I like it. While it took a small amount of learning curve to figure out the Pentax 645Z, the use of this lens surely helped. It is tack sharp and compares favorable with my Canon 85mm 1.2 as well as my Canon 100mm Macro lens. Ive used it with and without a Polarizer and looking forward to testing it with ND Filters. It is considered heavy by some, but Im use to the 70-200, seems about the same.

Very very sharp

I have had the lens for approximately one week, and so far I have been quite pleased with it's performance especially at f2.8. The software upgrade to the camera was strait forward with no problems encountered. The anti shack system works well but can not be used in combination with HDR. At first I thought something was wrong until I shut off the HDR. The auto-focus did a lot of hunting, but in close up work focusing manually is the best way to go.

Another must-have lens!

I can't speak for its macro abilities (as I have not tested them), but this 90mm is in the same category with the other absolutely recommended lens for the 645 system, the 25mm f/4 AL (IF) SDM AW. Both lenses are pricey, but well worth the investment, as they won't disappoint. Both offer fast and accurate focusing, as well as amazingly detailed images. The silent built-in image stabilization works well, adding about 2 stops advantage in real world applications.

Just the right focal length...

...for couples, head shots, candids, macros. This lens is ultra sharp, the chroma is much better controlled then the older 645FA series lenses. I had been using the 150mm f/2.8 which is a great lens but with no IS and chroma just bad enough to make correction difficult I'm relieved to have this lens. The 75 was a little wide for portraits in my opinion so this lens fills the sweet spot. I purchased USED through B&H, first lens arrived with faulty Shake Reduction but B&H made it right and had another used one available. I've attached two photos, one at the closest focus distance and another at about 6-7 feet away. Corrected for exposure and crushed the blacks just a bit but I left the chroma and vignette corrections in LR off.

Excellent Lens, Ultra Sharp

I recently purchased this lens along with a Pentax 645z outfit and couldn't be more impressed. I have compared the results of this and several other Pentax lenses with comparable ones captured with my PhaseOne IQ180 outfit, and in every case the Pentax images are sharper, more detailed and with equal or superior color and bokeh. And, of course, the Pentax's dynamic range blows the PhaseOne away. This 90mm Pentax lens is simply outstanding and if it is an example of what Pentax has in store for us, all I can say is wow. I am a professional fine-art photographer and have owned most of the top Hasselblad and PhaseOne camera systems, but none have impressed me as much as the Pentax 645Z which, price-wise, sells for virtually pocket change. I pity its competitors.
