There are plenty of 50mm f/1.4 lenses, although many of them have designs that date back possibly decades. There is nothing intrinsically wrong in this as the 50mm has always been a high-quality optic, generally considered the perfect standard focal length for 35mm format. However, things move on, and even higher standards are now possible, albeit using complex designs and being very expensive to produce.

This new Pentax 50mm f/1.4 SDM AW lens aspires to be amongst the best of the best, and indeed it achieves that and at a price which is still high, but which is highly competitive within its own bracket. Add effective AF and all-weather construction where some much more expensive lenses are manual focus only, and Pentax Users have a very enviable package. Obviously, users of other marques will need to use the alternatives (notwithstanding any adapters that may be available), but Pentax enthusiasts can be confident that they can share too in the very latest quality optical designs.

4. Pentax HD D FA 70-210mm f/4 ED SDM WR

There has been a tendency for many lenses to get bigger and heavier and it is a welcome change to have a smaller, lighter and less costly option. Although we sacrifice one stop with the f/4 maximum aperture, for many applications this is not really a problem. Current cameras have excellent high ISO performance, and this can more than makeup for a slightly slower aperture. We do of course lose out on depth of field control and for some, this will mean the f/2.8 lens will be the one of choice, but where this is not an issue the f/4 versions will offer a trimmer product that is less onerous to carry around, provided of course that there is no penalty in terms of performance.

The f/2.8 lens is actually one of Pentax's star range of superior optics, but in fact, this f/4 version is not very far behind. The figures for resolution are very slightly lower, but the difference is not a deal-breaker by any means. It is even possible to make satisfactory images at f/32 where, although diffraction will certainly take the edge off the fine detail, if depth of field is the main requirement then it is a good thing that the smallest aperture is available.

Of course, what we can't measure is that indefinable “something” that makes an image glow and this lens does have some of that quality. It can't be given a quantity, but I can say that the Pentax-D FA 70-210mm f/4 ED SDM WR lens is now on my own shopping list and it comes Highly Recommended.
