Yes
:(I can't manage to find the funds for a 105 macro lens
at the moment any thoughts about these
Kenko Teleplus DG Extension Tube Set 12+20+36 for Nikon AF, found them with a company called microglobe.co.uk
for £99. Will they work with my D60 till funds permit?
I would apprecate any advice
 
Yeah they'll work have you got a kit lens with ure d60? If so have u thought of getting an adapter to reverse mount it? If not get some tubes a buy a raynox dcr250

Hi

Yes, they'll fit and work with the D60 fine.

If you are tying to use something like a 50mm f/1.8 for example, you'd be better off with a reversing ring.
 
You'll get more working distance with the longer zoom and still get plenty of magnification - much easier.

The Raynox DCR-250 close-up lens attachment is also good for most basic macro, and is even easier to use. It also has the advantage of not losing light which you get with tubes, and can make it difficult to get hand-holdable shutter speeds with a high enough f/number for decent depth of field. Under £40. DCR-150 if you don't need quite such high magnification, from here http://www.amazon.co.uk/Raynox-RADCR-0250-Makro-Vorsatz-Linsen-DCR250/dp/B000A1SZ2Y
 
The Raynox seems like a good idea but:amstupid: how does
it attach to the lens? will I need an adapter, sorry I did a
google but most sites where in German
 
One problem with extension tubes which I haven't seen mentioned is that they show up Chromatic Aberration and the more tubes you use the worse it becomes.

This is because all lenses have CA optimised for the focal plane - in digital cameras this is the sensor.

Move the lens away from the focal plane (in order to get closer) then CA will begin to become obvious and this will usually increase with the number of elements making up the lens.

Obviously this also depends on the amount of CA present in the first place.

I find that a single lens prime - like the "nifty fifty" gives best results with extension tubes.
 
^^^ Good comment.

When you start messing about with any kind of lens attachment you get various optical problems, mainly CA but also field curvature and vignetting which are less noticeable. Only a pukka macro lens addresses those things properly.

However, with macro it usually doesn't matter. Depth of field is always very shallow so three quarters of the image is out of focus anyway, also the main subject is usually close to the centre where CA etc is minimal, and you have to use a high f/number to get even modest depth of field and this reduces these aberrations.

If you're doing critical work like stamps or coins, you will have problems but for most popular macro shooting it really doesn't matter. That little Raynox jobbie has no right to be much good at all given the above (and the price) but just take a look at the thousands of great images shot with it on Flickr :) http://www.flickr.com/groups/raynoxdcr250/
