Pentax has at all times been identified for producing compact, elegantly designed lenses and it is just with the arrival of the Ok-1 sequence of full-frame DSLRs that the dimensions of the lenses has began to grow to be important and considerably out of step with that ethos. The present 70-200mm f/2.eight is an efficient instance of this, so it’s attention-grabbing that now we’ve got a brand new, considerably smaller and lighter 70-210mm lens, the truth is round half the load. The loss is the utmost aperture, decreased from f/2.eight to f/4, and for a lot of, this might be an equation that favours the journey photographer particularly. A beautiful discount in weight, a lovely discount in worth, so all that continues to be is to see if the efficiency is maintained and the lens delivers the products. Armed with the Pentax Ok-1 II full-frame physique, we set off on our journey of discovery.

First impressions see a really effectively made lens, with easy controls and a very good end to the high-quality plastics used within the building. There’s a offered petal lens hood that bayonets securely into place. There isn’t any retaining catch, however the hood stays put and reveals no tendency to be liable to being dislodged. Inside the bayonet is a regular 67mm filter thread.

The burden is a reasonably modest 819g or 859g with the hood hooked up. That is, as talked about above, lower than half the load of its f/2.eight huge brother and the lens sits effectively and balances effectively on the Ok-1 or Ok-1 II full-frame DSLRs. If one of many APS-C format crop sensor DSLRs is used the “35mm-format equal” subject of view turns into 107-322mm. The lens nonetheless balances effectively even on the smaller digital camera our bodies.

The zoom ring is on the entrance of the lens and has no impact on the general size of the lens. There are clear and correct markings of 70mm, 100mm, 135mm and 210mm. Even in 2020, the marking of 135mm reveals a photographic heritage that harks again to the Leica rangefinder cameras, a seemingly illogical size that’s the tipping level past which rangefinders had been now not correct sufficient and the SLR was higher for focusing accuracy. AF, after all, renders this considerably tutorial, however the focal size nonetheless lingers on. The zoom motion is easy and constructive.

Behind the zoom ring, a small plastic window reveals the main focus scale, clearly marked in each ft and metres. There isn’t any provision for depth of subject scales with this design of zoom. We then come to the guide focus ring, which is totally usable in each AF and MF settings through Pentax’s QuickShift system. The grip we tackle the lens must take account of the focusing being reside throughout AF, in any other case with fingers on the zoom management we may catch the MF ring by accident. This can be a consequence of the extensive MF ring being nearer to the digital camera physique, however with the suitable approach in holding then, this shouldn’t be a serious downside. Focusing is all the way down to 0.95m, or 3.1 ft, giving a most magnification of 0.32x. The shut focusing may be very helpful and particularly so at 210mm which provides enormous potential for shut taking pictures from a great working distance, so preferrred maybe for bugs and small creatures.

There are two lens switches, the AF/MF one being self-explanatory and the limiter limiting the AF focusing vary to 2m to infinity. AF is through an SDM motor, silent and quick in operation and an enormous advance on the unique SDM system. There isn’t any looking and the AF shouldn’t be solely crisp but in addition correct.

Optical building is 20 parts in 14 teams. The diaphragm has 9 rounded blades, which provide a round aperture from f/Four to f/9.5. Lens coatings are the brand new Pentax HD (Excessive Definition) multi-coating, providing even higher flare suppression than the earlier SMC coatings. The entrance aspect has a Fluorine SP (Tremendous Shield) coating to repel mud, moisture and grease. The lens can be weather-resistant, some of the advantageous enhancements to lenses usually prior to now few years.

The well-made steel lens mount is designated KAF 4, indicating that there’s an electromatic diaphragm. Because of this some earlier Pentax our bodies won’t be able to cease down the lens, however all latest ones might be positive. The Ricoh web site has an inventory of suitable our bodies.

There are hardly ever any dealing with quirks with Pentax cameras and lenses, that are easy and slick in operation. The lens is a good instance of a effectively designed and extremely useful photographic software.
