magnification (1:1) it has a working distance (front element to object distance) of less than 5cm. Typical for 50mm macro lenses, there is also a bit of a practical limitation - at max.

On the plus side, the lens features a Quick-Shift mechanism for manual focusing in AF mode. A focus limiter could have helped but it was omitted. In other words - the AF is a slow, prone to hunting and also fairly noisy. Consequently it takes quite a while to auto-focus from infinity towards 1:1 magnification. While this is no real issue for most conventional lenses, this generic approach is not the best solution for a macro lens with its potentially long focus path. The D FA 50mm f/2.8 macro has no internal AF motor and relies on a slotted drive screw operated by the camera. If you prefer a tighter focus action you can use a focus clamp to increase the friction. The lens uses duo cams, thus two inner lens tubes, that can extend quite a bit. The situation gets even worse when focusing towards the macro distances. While it has a metal mount, most of the body is made of plastics and, unfortunately, the used materials feel a little cheap here. Introduced back in 2004, the D-FA 50mm f/2.8 macro follows a different design language compared to contemporary Pentax lenses but the styling alone is probably a lesser aspect to worry about for most.

However, from today's perspective that was almost a fortunate decision regarding Pentax' upcoming full format camera. SR (Shake Reduction) mechanism Quick-shift focus mechanism HD and. Being a full format lens, it was a bit of an exception to the rule at a time when Pentax centered their strategy around the APS-C format. The Quick-Shift focus system allows for instant switching to manual-focus operation after the subject is captured in focus by the cameras AF system. Medium-telephoto macro lens Compatible with Pentax 645 medium-format cameras Fast f2. Just like most 50mm macro lenses, it is very compact, light-weight and affordable. In this review we will discuss a representative of the 'standard' category - the Pentax SMC D-FA 50mm f/2.8 macro.

When it comes to dedicated macro lenses, buyers have the choice between a variety of different focal length classes with their distinctive pros and cons. Review by Klaus Schroiff, published June 2015
