Start and End serial numbers are from Nikon Ai conversion lists, service manuals, catalogues and various books. Nikon Lens Versions and Serial Nos Lens Serial Nos. Confirmed - Earliest and latest serial numbers seen ^ lens added to list in last 6 months. For Bronica 6x6. I just bought an SQ-A and was wondering if it is possible to tell the camera's year of manufacture by the serial number. Anybody know? The standard lens for the S2 was a 75mm f/2.8 Nikkor P. The regular version of the camera uses chrome on the body, an alternate model called S2 Black was also available without the bright chrome. A similar version called Bronica C2 was also available, with a non-removable integrated back.

First post, please end up being soft! I lately obtained two Komura lenses (50mm and 200mmichael) for my Bronica S2. Nevertheless they wear't concentrate properly in my regular Zenza Bronics helicoid position (I has been cautioned this might happen - an choice lens build was recommended as the remedy to the issue, but the person recommending it couldn't provide me any even more information about what kind of substitute mount I might need!) Therefore right now I'm wondering precisely what I perform require to create these lens function on my surveillance camera. I presently have just the 75mm Nikkor and á Zenza Bronica heIical bracket (can't find a serial zero) that says '50', '75', '135' and '200' on the range scale - which is usually why I wished these Komura lenses would function OK. They definitely bayonet into the position properly, so they are usually definitely H2 lenses.

I've study up on the 'internet about a various helical mount for lenses 300mmichael and much longer. But I haven't ended up capable to discover anything about any some other helical brackets for shorter lens. The Bronica websites have plenty of detail on using all types of non-S2- fit lenses with Beds2's - so definitely I should be capable to make these lenses work: they were made for the T2 after all! I found articles saying these lens been around - but I couldn't discover anything to say what else I would require to make them concentrate Fine. I would very much appreciate any recommendations from any Bronica S i90002 proprietors out there who possess ever owned/used these focal length Komura lenses. Thanks a lot in progress, Maggie. Thanks for your responses so much.

The concentrate screen will be great - works flawlessly with my 75mmeters Nikkor, therefore I'm reluctant to alter it for these lens - it is usually fiddly and difficult to get the display screen working place on. The lenses are not really simply a little 'off'. The 50mm doesn'testosterone levels concentrate in my S i90002 no matter what range the issue. The 200mmeters doesn't focus at infinity, and the length scale is usually way off - by various hundred percent. I also observed since publishing that there is usually the exact same issue with the diáphragm on both lens.

Outside my helicoid mount the motion is easy and gentle, and the aperture even, on both lenses. Inside the support the action is very stiff broad open - I can just get lower to y/4, can't get to y/3.5 - and the aperture doesn't get narrower than f/11 actually though I switch the band. The aperture furthermore distorts when shifting from y/22 down to n/4. This happens precisely the same on both lenses - it can be nearly as if the metal nub that moves the diaphragm handle on the lens will be in the incorrect location for both Komura lens. This can make me believe the seller was correct, and I need a various mount. The lens do bayonet into my helicoid - easily and easily, without pushing - so I'm still persuaded they should work OK with my camera as soon as I find out what I require to make them work. Once again I'm certain I wear't possess a damaged helicoid, as my 75mm Nikkor provides no problems with placing any y/stop, nor with a distorted aperture.

Is usually there a Komura internet web site where I can examine the lens seriaI numbers to see specifically what I have obtained? I'meters beginning to believe the vendor was correct when he stated I need a different helicoid.

Thanks a lot for your response! Hi, Perform you currently understand this site? Probably the greatest Traditional Bronica Site I have found. For the H2A it states: Focusing Band When making use of Bellows Connection or long focal size interchangeable lenses (105mmeters, 300mmeters and over 300mmeters) outfitted with their personal focusing techniques, get rid of the surveillance camera's focusing band. 1 - Press the concentrating ring discharge key and angle the focusing band to the still left (counter-clockwise), after that eliminate the concentrating band.

2 - To come back the focusing ring, place into entire body mount, coating up the red dots on the focusing band and entire body bracket. Twist the concentrating ring to correct (clockwise) until the focusing ring release button button snaps closed.

Nothing at all about altering the helicoid support for a 50 or 200 mm lens. Probably the trouble is definitely in the two lens itself. Regards Leeuwtje. My response is certainly a little bit 'after the event' but it relates to some findings just recently made with my very own Beds2A system. My lenses focus correctly at the infinity cease but 'sharpest focus' will not really coincide with helicoid distance weighing machines at closer settings. My Beds2A came initially with the 80mmichael Zenzanon n2.4 and helicoid range weighing scales for(I believe) 75mm and 80mmichael lens. After purchasing a 50mmeters Nikkor, I bought a helicoid noted for 50, 75, 135 200mm lenses but decided to swap the range scales only because the eBay obtained helicoid acquired some various other mechanical issues.

Today I notice the considerable lack of contract with sharpest concentrate and range marking on thé 135 and 200mmeters lenses I've simply purchased. I question, perform Bronica helicoids vary in the pitch of their strings?

I can't believe of any other description since this is s problem of 'climbing' and not really 'counter'. The last mentioned being described by the placement of the surface glass focusing screen. Obtaining back to y'all on my Komura lenses. A little lighting cleansing and more careful mounting of the 200mmichael lens, and it functions fine. Infinity is a little smooth, but I like my photos like that! I delivered the 50mmichael lens to become repaired. It evidently had been taken aside and reassembled incorrectly.

My repairer do a fine job (found him at a camera fair) for a affordable price. Once again pretty gentle at infinity, I'meters sure it would trouble other individuals but not me Since after that I've bought a 2x converter and a set of expansion tubes. All function fine with all the lenses, and make my little kit pretty versatile therefore long as I use a sturdy tripod Thanks a lot all for your help and suggestions!
