Diopter/Close-Up Filter Test

[olrac]

I received my hoya close up filter set yesterday it includes the following filters

+1
+2
+4

I also purchased a +3 as well.

I decided to test these little buggers out last night so i took photos on an apple on my coffee table.

the results are here....

For the first half of the test was just focusing on any part of the apple and it is a little distracting when you look at them in sequence.

the second half is better where i am trying to focus on the base of the stem.

Just a note with each increase in magnification the working distance became closer so by the end I had move the camera about an inch closer to the apple than when i had started.

Well let me know what you think.

they get you up close and personal, I find that it is hard to tell how good your lenses are photographing an apple though. the shine can hide detail.

When I got mine (nikon 5T) I was trying to figure out maximum sizes, depth of field etc using common things I had at hand when a friend walked past and asked me what I was doing. When I explained, he said why dont you just photograph a ruler??

This really hadn't occured to me at all and made so much sense that I dug out an engineers rule I had and photographed it.
I had it perpendicular to the lens axis to determine closest reproduction ratios and I put it at 45 degrees to lens axis and focused on a point midway along the ruler so I was able to get a good idea of depth of fields that I could expect using different apertures.

finally, because the ruler is square and even, I could determine any distortions I might introduce.

The ruler I used had good texture, scratches etc and was matt finished so no shine to hide details. Of course I used the tripod for repeatability between test shots.

my face was like homer simpsons when my friend said just use a ruler d'oh!! I had planned to use coins or anything at hand and maybe measure them afterwards!! but now I just look at my pictures and everything I need is right there.

sometimes you just dont see the wood for the trees.
