I had already decided I would buy a Canon because there is a wide variety of
successful lens mount adapters that make it possible to attach my Pentax M42
screw-mount, K-mount, and Olympus OM System lenses to a
Canon digital SLR and achieve infinity focus. The use of lens mount
adapters for these lenses proved to be very successful.
When I found a great deal on a
Zörk
Panorama Shift Adapter (PSA) that had a Nikon mount,
so I ordered this mount. This PSA enables the use
of my Hasselblad 80mm lens on my Canon with a shift
function.
The lens adapter mount "industry", if it
could be called that, has made some advancements. When I first started
looking, the adapters simply bridged the gap between the lenses I
have and the bayonet mount of the camera. They adapters were nothing more
than flanges. And worse, many were imprecise resulting in cases where
infinity focus was not available.
Infinity focus is important because one needs
to be able to take pictures of subjects in the distance as well as close-up.
If the adapter does not give infinity focus, the photography using it will be
limited to close-working distances. This is not a full solution and
os impractical for my needs.
This adapter is very good. I
have used adapters from various manufacturers for Pentax
M42 & K mount, Olympus OM, and this by far is the most
solid, well-made adapter I have seen.
The
Zörk
Panorama Shift Adapter (PSA) mounts securely
to the adapter. The adapter mounts securely to the
camera. There is no "slop" in the fit. The adapter stays
locked to the lens (or in my case the PSA) so you can
treat the lens just like any other Canon lens (with
regard to mounting and unmounting). Of course if
you have several lenses this can become a costly
approach. To save money one can simply own a
single adapter and swap it across lenses. The
quality of this adapter is such that it will work well
and hold up to repeated coupling and uncoupling,
something the cheap adapter is not known for...
As usual, one must focus manually (like photographers
did for 100 years...) and set the exposure manually
(though my Canon TTL meter works in AV and M modes
allowing reasonable easy exposure setting).
As some have correctly pointed out, there are lenses
that may be incompatible with your camera - best to
research this before you purchase the adapter and
especially, before you mount the lens and find out
something "hits".
I am using this to mount a
Zörk
Panorama Shift Adapter (PSA) to a Canon
EOS 5D Mark II. It works perfectly. Since this set-up is
essentially an
adapter-mounted-to-an-adapter-mounted-to-a-lens, the
amount of "slop" could be multiplied. But because both
adapters are high quality, the lens feels solidly
mounted to the camera with no looseness - just what is
needed for precise infinity-focus and a flat field
aligning with the sensor.
The added bonus for me is that I can now share my PSA
with my Nikon-toting friend, and he can share his Nikon
lenses with me!
This item is well worth the price, and comes highly
recommended!
I purchased and in four days received the
adapter pictured. In my case the Canon rear lens
cap did not come with the adapter, but I had one already
so lesson learned. The free shipping from Amazon
came at a cost of the missing part. No big deal...
