macro lens or extention tubes



I wondered you preference. I've read some John Shaw, and he (at the time of writing) leanded towards using tubes and between 105 & 200mm. I agree with his logic (lets you stay further away from the subject, thereby not disturbing it... among other things.)

One plus for macro lenses is that I keep hearing how great the optics are. This seems to be a common thread around them... to the point that I wonder if it has something to do with the demands of macro work that it must have it.

I just wondered what you (and others) thought.

This is mainly dependent on whether you are shooting on film or digital, but most lenses have higher resolution capabilities than the medium upon which you record the image.
I personally prefer extension tubes as they can be used on all lenses, I often use them with long lenses as they reduce the minimum focusing distance, for instance the min focus on my 600mm is 5.5 metres, with a 12mm extension tube this comes down to about 4.2 metres and with a 25mm tube its about 3.3 metres, particularly good for small birds or close head shots, you do lose the ability to focus to infinity when tubes are fitted though.
Macro lenses will (generally)give better edge of frame definition, but as most subjects occupy the central areas of frame and the surrounding area is often the out of focus background you will not really notice the difference unless you want to photograph very flat subjects in close-up.


I am getting quite confused with all this macro business (doesn't take much to confuse me).

Having just purchased the C750UZ, I've been going around photographing all manner of things close up in macro.

Can the macro mode be used in other instances, or am I misunderstanding this post entirely....?
