I must admit to often forgetting to switch the meter off. The centre position switches off the meter.

The settings are for Automatic exposure based on the aperture chosen and manual which gives recommended shutter speed again based on the aperture. There is a 3 position switch on it operated by pressing in the centre section and rotating the outer part. It takes it's power from the main camera battery. If you do not switch the meter off it will drain the battery quite fast. I find it to be fine as far as exposures go once you have determined your personal film speed just as with any other meter.ДЄs I understand it the meter is centre weighted only and I use it as such. I have been using one of these for the last 20 years or so. Hope I haven't put you off but just some tips to think about. The AE_II does speed up the picture taking experience. What you go for depends on how fast you want to shoot. On the whole I decided not to get a metered version and buy a plain prism and spend the money on a seperate hand-held meter. It should come standard with a -1 strength. All will accept diopter adjustment lenses. Mind you any prism is a must for portrait mode shooting, landscape are fun with WLF. The difference between the AE-II & the non-metered version in weight is very slight but the latter AE-III is much bigger and heavier. The AE-III is better version (more money and has spot function added). Depends where you point the meter to ensure a good exposure. Now as to the metering the AE-II has Average (full-frame) and Centre-weighted measurements which are fairly accurate - but not like matrax metering accuracy in 35mm cameras. The AE-III adjusted the designed flaw and the issue was resolved. When meter is off it's not really off more like in stand-by mode. I found was OK but does drain the camera battery even when switched off.

However, I did try out the AE-II for a 2-week trial but didn't keep it. 90mm f2.First off the ETRSi camera system is great and I have one myself but use a plain non-metered prism.1000mm f6.3 Astragon (manual diaphragm).The original lenses are MC, EII are revised versions, and PE are the final version with 1/2 aperture stops. 300mm f4.5 Auto-Zenzanon (uses large bayonet mount).80mm f2.8 MC Zenzanon by Carl Zeiss Jena DDR.It is necessary to remove the Bronica focus helicoid to mount. The Tele-Nikkor lens system requires a seprate focus module. 105mm f3.5 Auto-Nikkor (with leaf shutter and uses large bayonet mount).A variety of different Zenzanon branded focal length lenses were made as the supply of Nikkor's decreased.Д¬ameras like the ETR, SQ and GS use leaf shutter lenses. Alternatives were needed and a 80mm f2.8 MC Zenzanon by Carl Zeiss Jena DDR was produced.

This situation led Bronica to have a very low supply of the standard 75mm lens when they were to announce the newer Bronica EC series of cameras. Nikon decided not to manufacture lenses for Bronica, so the company decided to produce their own optics under the brand name Zenzanon. This is also great for making, adapting and hacking your own lens. This also made it easy for many companies to manufacture automatic or preset diaphragm modules with built-in focusing to attach to an existing lens head design not originally made for the Bronica. This made it easier for manufacturers to easily produce many different types of lens heads that share the same focusing module. The lens mount can also attach in three different ways with a large bayonet, small bayonet and a 57mm screw mount with a 1mm pitch. Unlike more complicated leaf shutter lens designs, these Bronica lenses do not require built-in shutters or focusing. The early cameras of Bronica were focal plane SLR cameras such as the Bronica S2, C2, EC, etc. Taped lens onto extensions and focusing helicalД«ronica was originally unable to manufacture it's own optics and hired Nikon.
