Extension Tube Question

[H@rry]

I have a Nikon D40 with the kit lense. I bought a set of Kenko extension tubes: 12mm, 20mm, & 36mm. If the coral is 4 inches back from the glass the only one that will focus is the 12mm. Is that due to the quality of the kit lense? I want to order the 105mm macro lense. Would that do the same thing?

I'm kinda disappointed with them. In order to get a really good closeup I'd have to move the corals right up to the glass (which is not possible with some of them). I could probably get the same thing I'm getting now with crop and zoom in PP.

That's what extension tubes do. The give higher magnification by decreasing the minimum focusing distance. You'd most certainly have better luck with the 105mm but the tubes will still come in handy. They also can take quite a bit of practice to get the hang of.

You can also get a Canon 250D or 500D closeup filter.

Still will need the subject very close, but you will be able to get crazy detail.

Much cheaper than a macro for the time being.

However, nothing will ever replace a 1:1 macro lens.
