Dear Ashok, above all I would like to congratulate you on buying a F2 AS model for little money! $300 is a very fair price for a F2 AS in good condition. To answer your questions: 1. I own a F2 S which has the prism DP-2. The AS model has the prism DP-12 which is more up-to-date against the DP-2. My camera hasnīt that small slide switch but I assume itīs a battery check indeed. 2. Sorry, I simply donīt know it. I never wanted to take any multi exposures. 3.+ 4. The lever you have described is needed to remove the prism. You just have to press the little button on the back of the camera you have mentioned in question 3. Then push the lever on the right side of the prism against the finder housing and then move it downwards whilst pressing the other button et voilā! - You hold the finder in your hands. 5. You can meter the light up to shutter speeds of 8 seconds. To do this, you first have to set the shutter speed dial to "B". Then press the little button in the center of the dial. You can now move the dial further to the left and you are able to choose those settings which are marked with little red numbers something above and left of the normal white speed markings.By turning the dial within the sector of the red marked long shutter speeds you can meter the light exactly the same way as if using "normal" shutter speeds. To set the determined longer exposure times than 1 sec. to the camera, you have to lift up the collar of the shutter release button and set it to the "T" position ("T" means "Time", I assume). You now are able to choose shutter speeds up to 10 seconds by using the self-timer! Yes, thats true! I hardly couldnīt believe that when I read about it the first time. A brilliant idea of the Nikon engineers of those days, isnīt it?!? Unfortunately that doesnīt work with a motor drive MD-2 attached because it blocks the self-timerīs lever. Ashok, I will work out how to make multiple exposures. I am interested in this stuff myself because I am a F2 user who wants to control his camera in every respect. I will contact you again when I find out how to manage it. Please visit "Michael C Liu's Nikon & Nikkors Resources" on the internet to get more F2 related info soon. The author will publish the complete manual soon. He has done that with the F manual a few months ago. These sites are great Nikon stuff! Navigate to: http://www.mir.com.my/rb/photography/hardwares/classics/michaeliu/index.htm Best regards and have much fun with your F2, itīs a great tool. I use it besides my F90x and my two FM2n and I donīt want to miss it. Itīs a feeling of itīs own to work with this professional camera. -------------------------------------- Kay-Christian Heine Schleswig-Holstein, Germany -------------------------------------- mailto:[EMAIL PROTECTED] --------------------------------------
