Ich habe selbst noch keine Erfahrungen mit den folgenden Objektivrückdeckeln von OP/TECH gesammelt, aber da es hin und wieder Beschwerden über die Original-Objektivrückdeckel gibt, wollte ich Euch auf diese Alternative hinweisen. Angeblich sitzen diese Deckel fester als die Originaldeckel, sie besitzen auch einen rundum aufliegenden Dichtungsring und es gibt sie sogar in Doppelausführung:
http://www.optechusa.com/product/detail/?PRODUCT_ID=85 ZITATThe LENS MOUNT CAP from OP/TECH USA is sure to be a hit with both amateur and pro photographers. It's no ordinary cap… the benefits and versatility are sure to please. It's designed with an O-ring seal which creates a positive contact with the full perimeter of the lens mount area to really lock out dust and moisture. It also offers a tighter friction fit over traditional caps that come with the lens so that it provides better protection to the lens mount area. This ensures that the LENS MOUNT CAP is securely held in place while in storage or transit. The LENS MOUNT CAP is available in single or double versions for several lens models. The double version is a huge space saver as it enables the photographer to safely and securely lock two lenses together. Keeping gear protected in a compact fashion really helps the active photographer organize and plan for their next photo adventure.
By using the Double Lens Mount Cap on a single lens, you can change lenses faster than ever! Remove the lens from your camera and immediately apply it to the open end of the double Lens Mount Cap. Then simply remove the other lens and put it on the camera. Less open time means your camera's delicate interior stays cleaner!
Step up to more secure protection with the LENS MOUNT CAP from OP/TECH USA. It's the final touch that no lens should be without!

(1101161) SONY/MAXXUM, SINGLE FITS MOST SONY/MAXXUM LENSES (1101261) SONY/MAXXUM, DOUBLE FITS MOST SONY/MAXXUM LENSES[/quote] Persönlich bin ich mit der griffigen Formgebung der schwarzen Originalkappen LR-1000 sehr zufrieden (viel besser zu greifen, als manche Kappen von Fremdanbietern), aber ich kann mir durchaus noch einige Detailverbesserungen vorstellen, die ich hier ja schon mal geäußert hatte:
(Preise Stand 2012-04) (1101161) SONY/MAXXUM, SINGLE 11,90 EUR (1101261) SONY/MAXXUM, DOUBLE 21,90 EUR
Besser fände ich es jedoch, wenn Sony selbst verbesserte Rückdeckel rausbringen würde...
