closeup filters - opinions and optins

[ranarama]

I've had a closeup filter (+3) for about a week and I really like it. It's turned my Tamron 24-135 somewhere near a macro lens for around £30. I didn't know what to expect from it quality wise but I have to say I'm fairly impressed (although I am easily impressed so don't let that mislead you). What do you think about this option in comparison to extention tubes and real macro lenses. Both of which come in at quite a bit more money.

To compare I did another shot tonight without the filter on. This is as clsoe as I could get...

Just added a retake from tonight for comparison without the filter. I've left them together as I thought it would make the scrolling easier. That was taken at f36 on a 10s exposure. I meant to do a f5.6 but put the camera away before I realised I'd not taken one (buffoon).

If nothing else I've surprised myself as I thought the difference in ability to focus closer in would be better. Maybe I should get a +4. Having said that I'm loving the really shallow DOF it's giving me.

Any people with proper macro lenses care to comment?
