Pentax smc DA 15 mm / 4,0 ED AL Limited

Zitat: Der mit Blende 4 lichtschwächste Testkandidat für 700 Euro zeigt ebenfalls einen kräftigen Randabfall bei Auflösung und Kontrast.

Zitat: Das Weitwinkel für die K20D hat es nicht leicht, denn obwohl die Lichtstärke eher gering ist, bleiben die Randbereiche bei voller Öffnung recht schwach. Dass die Schärfe bei Blende 8 gleichmäßiger wird, ist angesichts des Preises von 800 Euro ein schwacher Trost. Getestet an der Pentax K20D.

Zitat: The SMC-DA 15mm f/4 AL ED Limited is a another desirable pancake lens by Pentax. The lens is capable of producing very sharp and contrasty images at medium aperture settings. At large apertures the border quality is somewhat softer so it may not be the first choice for available light photography (handheld) ... assuming that you can find a better one. The vignetting is hefty at f/4 so it´s advisable to stop down here anyway to get rid of the problem as well. The amount of barrel distortion and lateral CAs is pretty decent for a 15mm lens. The AF speed is very high although that´s usually not a really serious criteria for a wide to ultra-wide lens. The build quality of this tiny pancake lens is great and it´s nice to see that a manufacturer still cares for high quality metal designs in this sea of cheap plastic lenses out there. Regarding its high price tag of around 650€/550US$ you´ve to be willing to sacrifice some bucks for this privilege but it´s worth it.

Zitat: Pros: + Compact and lightweight + High quality aluminium construction + Quick shift manual focus system + Built-in sliding hood (but see below) + Good flare resistance + Almost no distortion + Small 49mm thread, doesn´t require slim filters Cons: - Rather soft at F4 F5.6 - Hood design causes problems with filter use (particularly square systems)
