Several hoods will fit like PH-S49 (50mm) and screw-in type metal and folding rubber hoods I give this lens a 10 even though I rated a 9 for most of its characteristics.

Posted : 5 Jul 2011 9:00AM by John Riley : Features Handling Performance Verdict Specification Traditionally, the standard lens for 35mm film cameras was the 50mm. With the advent of the APS-C sensor, the same field of view is now obtained with a lens of 35mm or thereabouts, and here we have such a lens from Pentax. The ubiquitous standard zoom covers most requirements for the beginner photographer, but clearly Pentax feel that the time is right to offer a traditional standard lens option for the digital SLR range. Is this the lens to lift our vision from the seductive trap of the zoom lens? Does it offer an improvement in terms of quality, or some other advantage with its simplistic approach? Let us now tread the path of discovery.

The Takumar branded lenses were well respected for the line of Super Takumar designating the very well performing coating applied to the lens as well as the optical formulas that make up the lenses while a majority of the industry was still satisfied with the plumb coating.

Asahi Pentax soon would introduce the Takumar Super-Multi-Coated line of lenses as the industry had just caught up with forms of the multi-coated optics. Eventually Asahi Optical and Pentax would slowly shift much of there lens production under Pentax name and would transition some of the successful designs first introduce under the Takumar name to the Asahi/Pentax badged as well as the SMC abbreviations. Eventually the Asahi partnership would disappear and sole name Pentax would be used. Pentax lenses would see many feature changes to answer the market. Features such as the incorporating Auto-Aperture with the M42, light weight and compact with the M series and Aperture・ PENTAXのデジタル一眼レフは、開放測光に不可欠だった交換レンズからの絞り環位置情報を受け取りません。そのため、フィルムカメラ用の従前交換レンズも絞り情報をデジタルデータのみで伝えるようになり、なおかつ、絞り開度をカメラ側から設定操作できるようになったAシリーズ以降の交換レンズでないと、自動露出機能が使えません。そこで、それらデジタル一眼レフで自動露出機能が使える各シリーズ交換レンズのマウント構造の概要と、各レンズ性能の概要や特長について、以下に述べることにします 。 ・ ●smc PENTAX-Aシリーズ smc PENTAX-Aシリーズ交換レンズは、カメラ側からの絞り開度の正確なコントロールを可能にしたAシリーズカメラのためのものです。この機能を追加したことでシャッター速度優先自動露出が実現し、従前からの絞り優先自動露出と組み合わせて、プログラム自動露出も実現しました 。 これの前のシリーズであるMシリーズとそれ以前の「Kマウント」では、カメラ側から絞りを動かす機構は自動絞りのためだけのものであり、カメラから操作する絞込みレバーの移動量と絞り開度とが比例関係には無くて、交換レンズをカメラに取り付けると開放になる絞りを、レリーズすることで交換レンズ側で設定した絞り開度に戻すだけの単純な機能しかなかったのです。そのため、Mシリーズ以前のものは「クラシックレンズ」と位置付けることがあります 。 Aシリーズの交換レンズに採用されたマウントが「KAマウント」です。これは、絞りの制御の方法について、カメラから操作する絞込みレバーの作動量と絞り開度とが比例するように絞りリンク機構を変えた外に、マウント面に電気接点を設けて、これにより交換レンズの最小絞り値と、その最小絞りから何段目に絞り開放があるのかをデジタルデータとして伝え、また、絞り環に 「A位置」というものを設け、その位置に設定していることをカメラに伝達する機能を持たせました。このときにはまだ交換レンズ内に電子基板やROMなどは設けていないので、6個の電気接点の「導通」と「絶縁」(ONとOFF)の組合せによって、そのレンズ固有情報をカメラに伝達する仕組みでした 。The zoom lenses below can be used with both Film and Digital Pentax SLRs.
