Here is a rarity, I looked all over the internet one day for a picture of one of these lenses and only found the Komura original specs listing. The 152mm f3.5 Komura lens on offer is in near mint condition with almost no signs of use, perfect glass and shutter. This lens will work in a Polaroid 110B/900 4x5 conversion on a 900 body, rangefinder can be re-calibrated to suit this lens with about a 4 foot min focus distance. This is a routine conversion service I offer, 10 years of experience in Polaroid 110B/900 4x5 conversions. Why would this lens need to go into a 900? the 110B just does not have enough room under its hood for this large lens, remember, we are fitting a Pinto with a 429 cubic inch big block V8 and trying to close the hood here, (LOL!) I am seriously considering building a 900 4x5 with this lens as it would be an excellent candidate for hand held 4x5 photography, Mega Bokeh! there is a bit of an inconvenience in that being mounted on a Polaroid 900 one will need to unscrew its really large front element out of the shutter and stash it safely away before you could fold up the camera. so I decided to leave the decision of which camera this lens is destined for up to you film camera enthusiests out there. Don't forget, you always have that option of mounting the lens on other cameras in your collection, this lens can be pulled out of the 900 4x5 anytime and the focus/rangefinder calibration will not be altered. $500.00 plus $20 shipping for USA, foreign is more Payment by means of Check or Money Order preferred, direct bank deposit, Western Union Credit card use is at my sole discretion, approval of credit card use is at my sole discretion, if approved shipping address and billing address must match, shipping cost will be higher for credit card transactions I do not use PayPal so don't ask, I may use Google Checkout but only for U.S.A and Canada residents, No foreign credit card transactions.
