Was I sold a 'pup'? Tamron lens box says AF55-200mmF4-5.6LD MACRO. Can't find macro setting on lens or instructions. Looking at your site, Product Details says 'No Macro'. So what's going on???????

This is a macro lens, and I can't find it has an auto focus nor can I find if it has a chip, or even any electrical connection. The sharpness though should be good.
When you are using a non chip lens on a Nikon, you only can use it in manual. So you have to put the main dial to M. Then you have to focus manual and just take a shot. the result will be to dark or to light, unless you already knew hoe much light you have and dialled the aperture and shutter time in correct.
For macro you want a large aperture number, to have as much sharpness (large depth of field) so the best thing is to choose f 8 or 11 and turn down the speed till you have a good light picture.
I found a forum about this lens, but they did not say a thing about the specs.

I get the same issue with that lens but on my new Canon 60D

The lens can be used on Sony's alpha-series digital SLRs.

Actually you are doing really well cause the Tamron specifications for that lens is 1.5m translated into real numbers that's 4.92 feet. If you want some serious macro let me suggest the Canon 100mm F2.5 Macro lens it's not all that bad for price unless you get the IS version then it's out of the park well sort of. Most of my macro work is done on a tripod anyway so the IS is a waist for me.

Here is a review on that lens.

Also is you are using the APS size sensor there is a focal factor of 1.6 so the 100mm lens just grew to 180mm and twice as fast as your Tamron. Cheers

Having gone over threee months without a response, I assume this is no longer a problem.

It's probable that although it's designated Macro, the lens actually only gets in fairly close. I recommend you buy a closeup filter which is a simple lens you screw on the front of your lens. You can different strengths for getting in closer. Otherwise treat yourself to a set of extension tubes which do the same thing but more effectively.
I hope that helps

With an SLR you only get true macro focussing on a lens that has proper macro focussing abilities. Unfortunately in the photogaraphy world, there are a huge number of lenses which claim to have macro ability but are stretching the term far too much.

Strictly speaking, macro means that the lens is capable of producing images on the sensor which are the same size as the actual subject or even bigger, at life size this is described as 1:1 macro. Your Tamron lens is only capable of a maximum 1:3.7 "macro", and that's only at the 200mm zoom setting with the subject no closer than 45cm from the lens. By SLR zoom lens standards, that's actually pretty good, but if you want to go closer and get greater magnification you need to either use a supplementary close-up filter lens or for better optical quality use a set of extension rings. The trade off with close up filter lenses is poor image quality and usually plenty of colour fringing and with extension rings is that if you're using a 2x magnification at 200mm, your f5-ish maximum aperture at 200mm becomes a very dark f10.

The only way to get good macro results is to either use a proper (=expensive) macro lens and excellent lighting, or use extension rings plus a good ring flash unit. However you can improve your macro by investing in a more capable zoom lens with a closer minimum focus distance and a better aperture at the telephoto end of the range. This can be expensive, or you can pick up some very cheap 35mm film SLR lenses. Using an adapter will never allow you to achieve infinity focus on a Canon digital SLR but you can get a close focussing 200mm f3.8 very cheaply. The crop factor of your smaller sensor means it will have the same angle of view as a 310mm lens but the aperture will remain at f3.8. As Canon digital SLR's have the deepest body register (lens to sensor distance) of the current systems then you'll also have the effect of using it on an extension ring. The downside is that you'll have to use the lens in a totally manual mode as no information will be communicated to your camera body. By mounting the lens back to front using a reversing ring you can achieve some really stunning macro magnifications but then you need a tripod, powerful flash and absolutely no wind... There was also a Makinon 80-200mm zoom which sells for next to nothing on auction websites, but it had a macro collar which allowed it to achieve around half size macro (1:2).

Alternatively, if the Fuji still works and does the job just keep it in your camera bag ready for those types of shots. overall, that seems the easiest and best solution unless you really want to get heavily into macro shooting.

I hope that I've helped you, please ask more if there's anything unclear. I've tried to keep a very complicated subject as simple as possible. Please also take a moment to rate my answer.

I'm not sure of the exact model number of your lens, but the hood should have a bayonet flange and rotating it in one direction or the other should allow it to then simply pull off.
