A prime lens has a fixed focal length so the only option to bring object closer or to move them further away is to either move the object or move the camera.

A zoom lens has a range of focal lengths that you can adjust without needing to move yourself.

I am not sure if there are any true macro lenses that are zoom so at the very least most macro lenses are prime lenses but not all prime lenses are macro lenses.

(When I say true I mean giving you a 1:1 image reproduction on the image sensor - there are plenty of zoom lenses that claim macro capabilities but I think those are generally 1:2 or maybe even 1:3)

As an example I have a Nikon 50mm f1.4 prime - that lens is not a macro lens, I also have a Sigma 150mm f2.8, that lens is a macro lens but is also a 150mm prime lens.

What existing lens or lenses do you have with your D3000?

Also what type of images do you want to capture (macro and non macro), also do you have a budget at the moment?

The reason I ask is there is no one size fits all solution each have their pros and cons but with a bit more info some options can be included / excluded.

I don't know what the secondhand budget is like where you are but at the moment I think your budget is going to be ruling out a new dedicated macro lens.

For flowers one big advantage you have is that you have more options to control the movement and also getting the camera close is not going to scare them off Wink BTW do you have a tripod? One issue with macro photography is having a very shallow depth of field so movement can easily change what you are focusing on although that is sometimes to your advantage so you can fine tune the focus by moving slightly.

If I was on your budget I think I would also be looking at the options like extension tubes, filters and even a (hope I get the name right) a reversing ring to allow you to turn the lens completely around.

Alternative both Sigma and Tamron (and possibly a few others) make a fairly low cost zoom lens in the range 70-300 mm, these have a "macro" option for closer focusing although as I said above not true macro as it is not 1:1 - these lenses are sometimes criticised for being a little soft at the long end but if you look at my portfolio I have been able to capture images like the butterfly with the Tamron lens - that did need a tripod as there is no image stablisation.

Is seems you like close up macro shots. You may find a set of extension tubes would be a cheaper alternative to a macro lens.

Could you share any url for diopters and extension tubes, that would be very helpful for me.

I've tried both reverse rings [on my old 50mm] and extension tubes [which broke and almost ruined the mount on my camera]

Don't buy cheap extension tubes! The little screw used to mount is very likely to break when you're removing the lens from them. It happened to me, a little panic, but I managed to get the ring off with a screwdriver. You don't want to be doing this.

Reverse ring is the cheapest way to go. Again they can be fiddly on the mount, but no screw to worry about. You really need to be using a lens with an aperture ring though.

Your best bet, on your budget, is to look towards the new Nikon 40mm micro. I've seen excellent results from people using these for close up macro shots. I used the 60mm for a while and managed bug shots, spiders etc ... and some say you need to use 105mm for that purpose.

I will be buying one of those myself at some point, for abstract/close ups. It will also double as a very good portrait lens.
