Olympus have just unveiled 2 new fast prime lenses for the micro four third format. The 12mm f2 and the 45mm f1.8, these lenses are made with the Olympus PEN cameras but you can be sure they will make their way into Panasonic AF101 camera bags

• M. Zuiko Digital ED 12mm f2.0 lens: This high-speed, single-focal-length, wide-angle lens is ideal for shooting high-quality, dramatic landscapes and street scenes in low-light conditions. It has a beautiful full-metal body and a snap ring that enables photographers to pan focus with a distance indicator.

• M. Zuiko Digital ED 45mm f1.8 lens: This single-focal-length portrait lens has a beautiful shallow depth of field which allows for background blurring effects that are not possible with the 14-42mm kit zoom lens. The MSC mechanism is great for tracking a moving child or pet, and provides a quick and silent focus mechanism for movies and still photography.

These two lenses join the new movie & still compatible (MSC) ED m14-42mm II R f3.5/5.6 zoom lens (28mm-84mm equivalent) which comes standard with the new PEN kit as well as the M. Zuiko Digital ED 40-150mm II R f4.0-5.6 lens, an extremely light, wide-zoom range with a 35mm equivalent to 80-300mm lens that offers versatility and portability.

I was filming today with my new Sanyang 85mm f1.4 lens using the Kipon adapter when I noticed a movement in shot that I was not expecting, on closer inspection it was found that the Kipon adapter is now failing.

I had been warned that this relatively cheap adapter would begin to cause problems but in less than three months of very light use is not commendable.

What happens is that the lens you are using has a rocking movement in other words you can physically move the lens up and down which should not happen. I accept that this was always a stop gap till the Birger EOS mount becomes available but a tad worrying.

I must admit to putting my 70-200mm f2.8 Canon lens on the adapter which will certainly have not helped though thats only been less than 5 times and the lens was supported.

My advice if you have the Kipon adapter is not to put any large heavy lens on this adapter and to use it sparingly.
