Just got a brand new 40mm f/2.8 micro nikkor lens and it is exhibiting a very odd behavior.
It seems that the aperture is stuck based on the available lighting. I can change the aperture but if the lighting is poorish it seems I can only select 3.5 as the widest open aperture. If I aim the camera at bright light I get the f/2.8 back. I am using manual mode. I just can't figure this one out. I have tried resetting the setting to default by holding the qual and the exp comp buttons wit the green dots for more then a few seconds and it seems to reset everything except for the custom functions. So I thought maybe the lens was defective. Unfortunately the closest best buy where I purchased the item from did not have another copy and I wound up driving to another BB about 1 hour away in order to exchange it for the only 40mm macro in all of southeast Michigan. So I get to this Best buy and there is apparently a roped off line but no one is in it. So I walked up the counter behind a gentlemen being taken care of by a young clerk. She looks at me like I am the biggest dufus in the world and says very rudely to go stand in this line. I oblige. When I get to her I explain my problem and would like to do an exchange. I went to the camera dept and met a nice fellow who asked me if it might be a setting on my camera. To which I replied it very well could be! Could I be allowed to to bring in my camera and test it. Meanwhile he brings up the potential replacement to the rude clerk and explains what I am doing. I left both lenses on the counter and ran out to the car. I came back in tested the camera with the replacement lens and bam it seems fine f/2.8 no problem. Then when I get home the issue persists. This time though I am better able to diagnose what is actually going on which seems to be the aperture is being controlled by the available light despite being in manual mode. Now I have a sneaking suspicion that this clerk just gave me back the defective lens just because she was having a bad day and did not like the looks of me or the way I talk, whatever it happens I understand as nice as I try to be not everyone is gonna like me and I may remind them of an abusive ex, father, etc. I dunno but the two receipts that they gave me for the original and the new do not indicate that there is any difference in the information for the lens.

This is something I just read in the manual: If the camera is in exposure mode A or M, aperture will automatically adjusted by up to 1.2 stops to maintain the same effective f-number at different focus distances. :/
What the? So weird. I guess its behaving normally. Back it goes. The whole point of this lens was to be able to use this at f/2.8 for low light macro work. Poo. |
