I would like to start taking close up pictures of flowers. I mean super-close up. I have a Nikon D5500 and would like suggestions on what lens to purchase. I think I need VR and do not want to use a tripod. Manual focusing is fine. I'm thinking of purchasing the Nikon 100mm or the 90 mm Tamron with VC. Anyone have any good recommendations? Thank you!
For high magnification work shot by available light you are going to want to reconsider using a tripod or at least a monopod. Image stabilization (VR, VC, OS or whatever) is of little use at high magnification and some sort of support is often necessary, even with the stabilization. The VC or VR can be nice to have for shots being done at less extreme magnifications.
Something that can help to use macro flash. That can make hand-held shots more practical, since the flash will act to freeze camera shake or subject movement... plus it can allow you to use a faster shutter speed. There are two primary types of macro flash: ring lights and twin lights. Personally, for up to around 1:1 or a little higher magnification, I prefer and use a twin light flash. I usually only use a ring light for higher than 2:1 (twice life size). This is because the lighting from ring lights tend to be rather flat at lower magnifications (even though my ring light has two separate flash tubes that can be set to as much as an 8:1 lighting ratio). It is also possible to use a standard flash for macro work, though most will need to be diffused to prevent too strong flash overpowering a close-up image.
The Tamron 90mm VC is a fine lens and would be a good choice. The Nikkor 105mm VR is also quite good. I would
not recommend longer focal lengths (150, 180, 200mm) as they make for shallower depth of field - which is always a struggle at higher magnifications - as well as making it harder to get a steady shot. Shorter focal lengths (70mm, 60mm, 50mm) can make for a bit more depth of field, a more compact lens, and easier handheld shooting... but also isn't something I'd recommend for higher magnification work as it puts you awfully close to the subject.
The Tamron will autofocus fine on your camera (as would the Nikkor 105mm in it's latest AF-S version).
Some macro lenses that
won't autofocus on a D5000-series camera include the Nikkor 200mm "AF" and the Tokina AT-X Pro 100mm "D". Those lenses (as well as some others) rely upon a focusing motor built into the camera body itself, which the D5000-series don't have (only D7000-series and higher Nikons have that).
You mention "manual focus is fine" and that's often the easiest way to do high magnification work anyway. With modern lenses that maintain an open aperture until the instant of exposure, it's pretty easy. Older lenses or any with manual apertures are another matter, because when they are stopped down your viewfinder dims down along with them (for example, this happens with a vintage 1980s era Tamron 90mm I've got... but that lens is an ancient ancestor to the Tamron 90mm VC USD you're considering).
As mentioned above, shallow depth of field is often an issue at high magnifications. With digital photography one way to deal with shallow DoF is a "focus stacking" technique, which involves taking a series of shots at slightly different focus settings. This almost certainly will need to be done using tripod (and, quite possibly, add'l devices such as a precision "focusing rail").
Some nice features of the Tamron 90mm VC USD ($649) include that it's an "IF" or "internal focusing" lens. This means it stays the same length when focused closer. Some macro lenses are not IF and virtually double in length when focused to their highest magnification... which reduces working distance between the subject and the front of the lens a great deal. For example, the somewhat cheaper Tamron 90mm "non VC/USD" ($499) and the Tokina AT-X 100mm ($349) are both non-IF lenses.
The approx. 12" minimum focus distance (MFD) of the Tamron 90mm is fairly typical of lenses around the 90 to 105mm focal length range. Keep in mind that MFD is measured from the sensor/film plane of the camera... so part of the camera itself (approx. 1.75"), the lens itself 4.84" with the Tamron 90 VC/USD and any attachments to the front of the lens (hood, filter, flash) will occupy part of MFD... what remains is the "working distance" between the front of the lens and the subject... in this case just over 5" when the lens is set to full 1:1 magnification.
The Tamron 90mm VC USD also has a smartly designed, 3-stage focus limiter. This can be used to speed up autofocus. It can be set to allow AF across the full range (0.3m to infinity), limit it to macro range only (0.3m to 0.5m) or limit it to non-macro range only (0.5m to infinity).
