Pretty much. Though I suppose it would be nice if someone posted a picture of a real set ofreal extension tubes (not like my converted TC) as an example of what they look like and how they can be used. As I understand it, they come in a set and you can mix and match (is that right?).

I really love the pictures that people are posting!

i'll post a pic tomorrow of my set. they are mechanically coupled to the lens aperture and are a set that i think is the barest minimum of what you need.
at least your remodeled 2X is also.

There you go, another person posting perfect butterfly pictures - makes me jealous!

I've never been quite clear about the Tamron's macro capabilities, or has there been more than one type over the years? Can you do close focusing with the Tamron throughout it's zoom range, or only at 300mm?

Thanks Harriet

Yes I understand there are 2 Tamron 70-300s.

I think most people have the same as my one the LD. DI.

Macro is only available in the 180 to 300mm range by slipping a little slider on the lens. Other focal lengths focus down to around 5 Ft or 1.5 Metres.

In macro, focussing is available down to around 3 Ft or .95Metre.

Interesting thread - I love the starting red admiral

I have not yet ventured into using extension tubes or whatever gizmos - just the camera and the lens is enough for me at the moment. Since I got a Pentax-A 50/1.7 lens today I tried a macro shot of an orchid, this time with a more shallow DOF than with my Tamron 70-300.

I got a lot of out-of-focus pictures, I am not used to a shallow f/1.7 DOF *lol* but then - cranking it up to f/2.5 - that one:



Hope you like it - and happy snapping!

Th.

I found a set of Rokunar close up filters in a drawer. Igot them about 20 years ago for my Minolta XG1. Now they fit on my Sigma 100-300 DL. This is a picture Itook using the#1 and #2 filters. It is a bit soft, especially compared to some of the great shots on this thread! I don't know if its the filters or the lens itself. But it is an interesting flower because of the extra petal growing on the stamen. This is the third flower on this plantto have that.
