Originally posted by Praestigium I found some threads on the matter but they were a little outdated.
I'm currently the owner of a Pentax K-X with an 18 - 55mm Pentax lens and a 28 - 90mm Sigma lens. However I find that neither of the two are cut out for Macro photography.
Any suggestions on how I should go about this? Should I purchase a new macro dedicated lens or perhaps purchase a macro zoom lens?
I have a budget of about $150
Cheers!
There simply is no "macro zoom lens" on the market. There are some zoom lenses, that claim macro capability. Firstly it is not true per definiton, as true macro lenses start with half lifesize magnification and most true macro lenses will go right to 1:1 lifesize. Secondly those "macro enabled" zooms do not deleiver the sharpness of a true macro lens. Somebody posted some nice example shots, comparing a macro zoom lens and a true macro lens and the advantage of the true macro was very pronounced. (Sorry, can't remember the thread.)
A true macro lens will be a prime lens of between 35mm and around 200mm focal length, with most of them in the 50mm and 100mm area. Thus they can be used for any type of shooting at far distances too and will demonstrate their usually very high sharpness.
Quite contrary to zoom lenses basically any true macro lens will yield very high image quality, even if you buy a twenty or thirty year old manual focus lens. So, at the end of the day, the final image will not show, whether you used a current AF macro lens with all bells and whistles for 600 bucks or whether you used an old Vivitar lens from the 1980s, you found in the thrift shop for 20 bucks.
