If you are not already aware of AI
conversions and their need and usefulness, please take a quick look at
the rest of my site to familiarize yourself with the process.
Most of the lenses I receive for conversion are
from individuals who have held on to their Nikon FTN, F2 and/or
Nikkormat cameras as long as they could but are now forced to move into
more modern bodies. They are still pleased with the familiarity,
durability and optical performance of the older lenses and want to keep
them in service.
I also receive many lenses from stores that deal
in used equipment. They have found that non-AI lenses are difficult to
sell at any price since there is a dwindling number of non-AI bodies.
Once converted, however, the range of potential buyers is greatly
The rest of the older lenses that come to me for
conversion are from repair shops who have found that it is
easier/better/faster/more profitable (I am not sure which) to send them
to me rather than develop their own capabilities or send them to someone
A few of the lenses that I convert are Series E
and autofocus models. In these cases, the owners want to take advantage
of modern lens designs, particularly zooms, on their surviving older
bodies. For this conversion, I install the traditional metering yoke.
An emerging category of my customers is developing
from eBay, other internet sites, trade shows and general buying and
selling. These persons are buying non-AI lenses at very favorable prices
and then sending them to me for conversion. It appears they end up with
a deal on a lens that will still be a bargain, either for their own use
or for immediate resale.
I am willing to help those of you in this last
category by saving you some time and shipping costs. If you are a
long-distance buyer, you could have your new lens sent directly to me
for conversion. I will let you know of its arrival and give you my
assessment of its condition. If it came from
an eBay seller, I could compare it to the description in the auction.
You can send payment to me by personal check, MO or PayPal. I would
convert the lens and send it on to you. If you are a long-distance
seller, you could mention the availability of my service in your ads or
on your auction listing to help increase the number of potential buyers.
You are welcome to link to my website if you think that would help.
Overall, I am looking forward to serving you in
some capacity. Please contact me if you have any questions or require
further information on how we might work together.
Basic information on my three types of
My Type A conversion ($25)
will allow all older Nikkors to mount and meter on all modern bodies
except the ones I have termed "Electronic Only." Current
examples of "Electronic Only" bodies are the D90, D80, D100, D70, D70s,
D50, N80, N65
and Fuji S2. With these bodies, my Type B conversion ($35) is
needed to mount the lens but there will be no TTL metering of ambient
light since their meters require the microprocessor found in the
Typical newer bodies which use
lenses with my Type A conversion for TTL metering are the D1 series, D2
series, D200, D3, D300, D700, F5,
F100, F4, F3, FM series, FE series, N90, N8008, N70 and N6006. With
these bodies, metering in the manual mode is supported. Depending on the
features in the body, you will also get aperture-preferred automation, TTL flash metering and "electronic rangefinder."
Autofocus and Series E lenses need
my Type C conversion ($35) to
meter at full aperture on the non-AI bodies.
Note: The D40, D40x, D60 and D5000 will accept
virtually all Nikon-mount lenses without modification.
In each of the three cases above, my
conversion will not affect the use of the lens on the bodies it was
originally designed to fit.
