<p>If I used a Canon FD 50mm lens on a full frame mirrorless camera with a suitable adapter, would the field of view be exactly the same as it would be on a Canon FD body such as the AE-1 ?</p>

I need a dry cabinet (dehumidifying cabinet) to store my Nikon 500 F/4 AiS lens. I'm not able to find one that can house it horizontally. Is it okay to store this lens vertically for long periods of time? Thanks in advance.

These bugs are so small and they just sit still. I'm not interested in chasing butterflies and fast moving ants. I make all my photos using a tripod and macro focusing rail.</p> <p>I've been shooting all my photos with a Tamron 90mm lens and 3 extension tubes (13mm, 21mm and 31mm) attached to the back of the lens but I still need more magnification. I need more magnification still.</p> <p>Will a 2x teleconverter help my cause?<br> Will a 2x teleconverter eat into DOF?<br> What about a 2-element close focus filter?<br> Would it be ridiculous to use a 2x teleconverter + 3 extension tubes?</p>
