Pentax SMC-FA* 85mm F1.4

by Steve Graham, 1998


FA* lenses are Pentaxes premier 35mm offerings, sort of equivalent to the Canon L range. The lens reviewed here is primarily aimed at portrait use, and comes with a heavy price tag.

Build

This is very solidly built, confidence inspiring lens, with a large bayonet mounting hood supplied as standard. The lens is quite short but it's wide construction and weighty (it tips the scales at a not insubstantial 0.55kg) feel give the impression of a "barrel of glass". It takes 67mm filters and is supplied complete with a soft case.

While in Singapore I dropped mine from a height of about 4 feet onto a marble pavement, where it landed front element down with a horrible bang. The lens cap popped of and the filter ring now sports a big dent, but apart from not being able to mount filters it functions as normal. If I'd had the hood fitted at the time I'm sure the lens would have escaped damage.

Optical

I bought this 7 element 6 group lens primarily for studio and available light portraiture and for low light use, purposes for which it excels. Results are very sharp, with a nice feel to the out of focus areas, probably helped by a nicely round nine-bladed aperture. I don't use it for landscapes but I've seen comments that performance is not great at infinity focus, leading to the belief that Pentax tuned this for best performance at near focus. When I have used the lens outdoors I've seen no sign of flare, perhaps due to the lenses relatively simple construction and deep hood.

Handling

Pentax's flagship FA* lenses make use of a "de-clutching" mechanism to switch between manual and auto-focus. This improves the handling as the focus ring doesn't revolve when in the AF position. When in the manual focus position the lens provides a better feel than most other AF lenses I've tried . Internal focusing is used so the front element doesn't revolve - helpful with graduate or polarising filters. The only minor annoyance (shared with many other lenses) is that it is impossible to take the lens cap on or off while the hood is fitted, and it's also very difficult to use polarisers due to the lack of access again due to the hood. Close focusing is marginal for a portrait lens - fine for frame filling portraits of adults, but not quite good enough to do the same with small children.

Compatibility

I've used the FA* 85mm F1.4 on all three of my AF Pentax SLR's (Z1p, MZ5 & Z50p) and as you would expect I've experienced no compatability problems at all.

Price

I paid around 6000 HK dollars (about 770USD or 475 pounds sterling) in late 1997 for this lens, which is rather e a lot for a short telephoto prime.

Conclusion

Quite simply superb - for portraiture and low light photography it's the best lens I've ever used.

The picture at the top of this review is a grab shot of my daughter, Alison, in normal early morning grumpy "get me my Coco-Pops" mode. It was taken using a Pentax Z50p, SMC-FA* 85mm F1.4 at F1.4 and something like 1/90s handheld (honest I do own a tripod). The Ilford Delta 400 film had been in the camera for about a year (it was my first SLR, since replaced in my affections by more upmaket models), and was developed in Rodinal - resulting in a particularily pleasant grain pattern don't you think?

Have you ever tried new FA77mm/1.8 ? I know FA85mm/1.4 is good,but there are some differences when comparing 77mm/85mm!

1.77mm give the smaller body which will give you more conveneintly handling! 2.77mm has the special coatings from the research of Pentax's degihner.This kind of coating tech can provide the more colorful gradation especially on the highlight of the image's color!

This is one of Pentax's finest lenses ever made, in construction, (feels so solid), and in performance.

Though there have been criticisms that it is slightly soft open wide, and it certainly is softer than my (slower) Carl Zeiss 90mm f2.8 lens wide open. But stopped down to the same f2.8 aperture then it is sharp.

The Pentax lens rips out incredible detail, colour and contrast, with out of focus areas that are quite smooth and pleasantly soft. It just imparts a vivid 3D feel to the whole picture.

Not particularly cheap as it's priced the same as fast Nikon and Carl Zeiss glass.

I got mine for $4600 HKD second hand in Hong Kong in 1996, about $600 USD

i found this lens better than the m42 85/1.9 and m42 smc 85/1.8, better than a contax zeiss t* 85/2.8, and better than a nikkor pre-D AF 85/1.8. i think of it as an indoor lens and the contax zeiss t* 85/1.4 as more general purpose, an indoor/outdoor lens.
