Close up lenses

I have been noticing quite a few people are using close up lenses on macro lenses. ie +2,+4 and +5.

My question what is the advantage of using these on macro lenses and also what is the disadvantages, to taking macro photos.

I have a 60mmm nikon lens and getting the 105mmvr soon.

Forget about +2, +3, +4 ,+n lens for 60mm or 105mm, in your case you should be looking for 5T or 6T diopters, this are discontinued, but look on ebay.

This will add magnification to your lens with minimun quality lost and let you focus closer.

Hi,

I don't think you need to focus closer when using the 60mm - you can almost focus on the end of the flat port if you try...

With the 105mm the opposite is true. You'll find that sometimes when you get close, the camera won't focus anymore. That's because the working distance of the lens is longer and the subject is closer than the minimum focus distance. This is where a diopter or close-up lens comes in handy.

The translation is that a +1 lens brings the infinity focus of your lens to 1 meter. A +2 to 1/2 meter, a +4 to 1/4 meter. You get the picture.

Thanks James,

So if the close up changing the infinity what is happening to the minium. ie the minium focus on the vr105mm is 30cm so if i put a +2 on does the min focus go to 15cm and infinity goes to 1/2m ? Am i understanding this correct.

If the infinity focus is 1/2m or less does this mean the lens cannot be used for taking a shot outside this distance?

Well the Aus$ was to good the the US$ so the Nikon 105mm vr lens is on its way.
