Tamron 18-250 Great as a macro too

Having given the Tamron 18-250 3.4-6.3 DiII a good workout on general shooting, tried a few more macro type shots. In comparison with my Sigma EX 50mm EX DG 2.8 Macro, I can honestly say the Tamron does an excellent job as well, good compromise and so far my favourit walk around lens.

This is the Tamron at 170mm full (Exif on image)



And one from the Sigma 50mm (Exif on image)

Hi Phil

As I believe I mentioned previously, I have acquired a Tamron 18-250 3.4-6.3 DiII like yourself, but have not used it so far for 'macro' photography. If it's not a stupid question (which it probably is, but I'm prepared for the 'brick-bats' !) precisely HOW do I use this for taking macro-photographs ? I have an ancient but optically superb Vivitar Series 1 (OM mount) 70-210mm zoom which had a special macro-mode switch (or something), but it weighs an absolute TON and it's so long ago since I last handled the beast that I've forgotten how it used to work ! Your assistance and advice about the Tamron would be greatly appreciated.......

Best regards
Richard

No such thing as a dumb question... only dumb mistakes!!

The Tamron 18-250 will focus down to about 8.5" from the subject, and using it at 18mm the object is still pretty small.

Luckily, the minimum focus distance of 8.5" is the same throughout the zoom range, so by zooming in you can in effect, shoot a Macro or an image that takes up most of the field of view.

This is what a Macro is, an in focus shot that fills the screen or field fo view, so you have a high res image that you do not have to enlarge to see, losing the resolution in the process.

Hi Phil

That's kinda neat.....so simply get closer to the object, but perhaps use a tripod to obtain a really sharp image !! I'll have to take my tape-measure with me in future....LOL !

Best regards
Richard
