According to Wikipedia... In film and photography, a prime lens is either a photographic lens whose focal length is fixed, as opposed to a zoom lens, or it is the primary lens in a combination lens system.
|My manual focus PRIME LENSES hibernating in the cloth closet|
You can see from the above picture that I have a few Nikon (Nikkor) and Leica-M prime lenses. Most of the time, these once highly sought after lenses are hibernating in my cloths closet!
I have used my selections of old Nikon and Leica M optics on my Olympus E-P2 and OM-D before, the experiences were not intuitive mainly because it is so bloody hard to get an accurate manual focussing on these digital cameras! Not until I try out my 25 year old 50/2 Leica Summicron-M lens on the GM1!
If you read that review, you will realise I LOVE IT!
Now with the Lumix GX85, it should be even better, right?
Pictures above show my 30+ year old Leica Elmarit M 28/2.8 true range-finder lens on the Lumix G85. The combination LOOK GREAT :)
But please remember that to mount a X brand lens to the M43 lens mount, you will need an adapter.
For me, I bought TWO adapters for this purpose, one for the Leica M lenses and the other for mounting Nikon primes on M43 cameras.
A word of advice, when it come to these adapters, go for the best. It might only look like "a piece of metal" to you, but a badly made adapter can really damage your camera lens mount, or jammed/stuck, resulting in a UNREMOVABLE prime lens on your M43 camera body!
You have been warned :)
For a M43 camera to use a manual focussing prime lens effectively, it must have good FOCUS PEAKING, most modern digital cameras with an electronic viewfinder will have focus peaking built in.
But what is FOCUS PEAKING?
Look at the picture above... Notice the RED HIGHLIGHT on the GX85 screen? That is GX85's focus peaking aid to show you the IN FOCUS area, now you can focus your manual prime lens with confidence and accurately!
By the way, since most MF primes were made for FULL FRAME film SLR, your 28mm lens will "behave" like a 56mm lens (28x2)..
Before I am blasted by readers, I meant the 28mm will have a FIELD OF VIEW of 56mm lens ;)
The Leica Elmarit M 28/2.8...
This was taken with the Lumix GX85 with the Leica M 28/2.8 at FULL aperture of 2.8, looks really good! Lets crop in...
This is the 100% crop, now you know why the Elmarit was one of my favourite film lens!
As I swapped to another Leica M lens, the GX85 is smart enough to ask me if I want to change the focal length setting, this is to optimise the in built IS (Image Stabilisation) to your third party lens! Wow!!
The Leica Summicron 90/2...

|The Nikon 80-200 F4 zoom at 200mm F4, notice the presence of heavy chromatic aberration, NOT ideal at full aperture!|

Famous Last Words...
The LUMIX GX85 works great with some MF Prime Lenses, I am impress with the IS working well even though it is not wearing a M43 lens!
Due to the "doubling focal length effect", however, I would stick to shorter prime focal length.
One of the best MF lens I like is the Nikon 50mm F1.4 "normal" lens! On the GX85 it "became" a 100mm F1.4 super short tele with beautiful bokeh!
GRAB them while you can!
