FotodioX OM35-PK-PRO overview

  • 1Description

This Pro Lens Adapter from Fotodiox enables the use of your Olympus OM lenses on Pentax K mount SLR and DSLR cameras. It features a durable brass construction with stainless steel finish and a leaf spring ensures a secure connection between the lens and adapter. Additionally, through the use of a 1.4x multi-coated focus correction lens, this adapter is designed to maintain infinity focus. This correction lens can also be removed to render the adapter as an extension tube for macro shooting.

This manual adapter does not maintain automatic lens control between the camera and lens; aperture priority or manual shooting modes should be used, as well as stop-down metering for exposure control.

    Pro Lens Mount Adapter for Olympus OM Lens to Pentax K Mount Camera is rated 3.0 out of 5 by 2.
    Rated 2 out of 5 by from Not Very Confident I purchased this to mount a pair of older Olympus mount lenses to my Pentax camera bodies. It does enable good focus to infinity, and it mounts securely to the Pentax bodies without issue. On the other side, the lenses attach with a good deal less confidence. They slot in appropriately, but in the turn they encounter growing resistance until they come to a stop with no positive click or engagement of the locking mechanism on the lens. They seem to be held in place mostly by friction. I took a few test shots, which turned out pretty well, but I wouldn't be confident taking this setup out in the field. I worry that turning the aperture ring on the lenses would lead to twisting the lens off the mount at inopportune moments.

    Rated 4 out of 5 by from Good gadget. I have 2 lenses for my old OM-10 - the Zuiko 50mm 1.8 lens that came ith the camera, and a Tamron 35-70 zoom. Both are good lenses and I wanted to try using them with my Pentax K30. The Fotosiox adapter came without instructions (maybe that's usual) but it did not really need any - it just went on the camera easily, and the Tamron went on the adapter easily. The Zuiko is one of those lenses with the tabs sticking out the back, and it won't go straight on - I had the trim the tabs a little to allow it to fit. Of course I had to take some shots straight away, and without setting the camera to use apature ring it took ok but overexposed images. After setting the camera up according to the instructions from Fotodiox's web pages it took properly exposed imaged. Because of the 1.4x correction lens in the adaptor, the 50mm lens becomes the equivalent of 50x1.5x1.4 ie about 110mm equivalent, iand it focuses nicely up to infinity. When set up as per the instructions the camera sets the shutter speed properly and the focus assistance feature (little red square in the viewfinder and short beep) tells you when it's in focus - this last thing was an unexpected but welcome bonus feature. I tried the adaptor without the correcting lens, and the Zuiko lens only focused between about 7cm out to about 60cm. But it does great macro like that. Now, while the Tamron worked well throughout its range of focus and aperture, the Zuiko 50mm did strange things when set to f1.8 - the image became blurry and had a blue tinge. It worked fine at f2.8. The effect can be seen thorough the viewfinder or on the screen with live view. It must be some internal aberration. Rember those tabs I had to trim to get it to fit? Maybe they are there for a reason. Overall, I'm very pleased with this small adaptor - it allows me to use these high quality glass lenses on my entry-level DSLR.
