My D5100 only works in manual mode with older lenses which is OK. The problem is that there seems to be no way to get a light reading other than with an external meter, or trial and error guesswork. Even the D1 would work on aperture priority and select an appropriate speed. Thanks Mike

It only will take pictures in full Manual mode, using any other settings gives a "Lense not attached" message.

For anything critical I take a series of exposures of grass and check the histo for good exposure, then check the histo every exposure during the session. I have used a Nikkor Micro 55 manual lens on a D3100 with good results using that method. If I am bracketing the exposure with other cameras, almost without exception I find that the 'correct' exposure and minus 1/3 stop seems to give the closest to the desired results. I still check the histo for confirmation.

A, You are right. The camera's like the D5100 have no coupling with non-CPU lenses, so the camera has no way of knowing that f-stop is set on the lens. On the other hand, in full manual mode some old lenses can be mounted on a D3nnn/D5nnn that cannot be mounted on some other DSLR Nikon camera's. A work-around would be: mount a CPU lens (like some AF-S kit lenses) and do an exposure reading in manual mode, then mount your non-CPU lens (and check the exposure on the histogram). Regards, Gilbert

I'm going to try this AF Confirm T-2 T2 Telephoto Lens to Nikon F Mount Adapter, from eBay. Apparently it tells the camera that there is a lense mounted and set at f2.8 so that the aperture priority settings should work on anything mounted on the adaptor. There are various mount adaptors available from the same vendor as the link below to the one I ordered. I'll update when it arives. http://www.ebay.com/itm/180992505258?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_3419wt_1162

My ROXSEN T-2 Telephoto Lens to Nikon F mount adapter ring with AF Confirm Chip for Nikon arrived today and it works just fine. Basically there is a 5 pin chip glued to a T2-Nikon adaptor ring that tells the automation that a 50mm f2.8 lense is mounted on the camera and it allows arpeture priority to function for lens mounted in it. It would be nice to be able to buy the chips and mount them on older manual Nikon lenses, tel converters, bellows, etc.

You can, either get hold of old or broken lenses and transplant the chip, or contact Bj¸rn R¸rslett who may supply the chips. Visit Bj¸rn's website... http://www.naturfotograf.com/index2.html

There is a feature on my D3 D300, etc that allows me to setup the max f stop and focal length for non-CPU lenses. This works very well. I dont know if the D 5100 has this feature.
