Just so you know, the DCR-150 works best with lenses longer than 100mm, while the DCR-250 works best with lens that are shorter then 100mm.

Use this page to see what kinds of results to expect:
Macro Extension Tubes & Close-up Lenses

Scroll past the extension tube calculator to the close up filter one. Also bring a tripod if you plan to use this on things that are not flat. Depth of field drops precipitously when using Macro. You need a steady hand a lot of light and likely a tripod to take pictures most of the time due to the high f/stop you will want to use.

Some numbers to help you:

Max magnification for the 18-135 is 0.24x (presumably at 135mm and minimum focus distance. Plugging that in to the calculator gives just over 1:1 (1.04x) which should be nice. Assuming the 70-300 is a modern sigma they claim 1:4.1 and 1:2 in macro mode. This should translate into as much as 2.6x and at least 2x lifesize.

I think the DCR-150 is perfect. Even on the shorter lens it fills the gap between your 0.24x and up to 1x It fits the filter threads with a quick snap on and off adapter etc.

BUT long term if you find you love macro you may want a dedicated lens for that. I have the DFA 100 WR and I have owned many macro lenses. I also own the DCR-150 and 250 and a bellows and extension tubes etc. All of these methods have tradeoffs. A macro lens is quite flexible but carrying the Raynox in your pocket is a simple solution for when you might shoot something up close but it isn't your main plan.
