Okeh Bokeh

I've just reviewed the new Tamron 70-180mm f/2.8 lens for EPZ and one unusual feature is the extended close up capability at the 70mm setting. This only works in manual focus mode, but it does give an extraordinary range of different effects, depending on distance (to a maximum magnification of 1:2, half life size) and aperture. The closer we go and the wider the aperture, the more dramatic the effect. I thought I'd have a further play.

First off, here's a close shot using f/16.

Then the same shot using f/2.8

Of course the technical shot shows the maximum blurring at 1:2 and f/2.8

This shot is an attempt to exaggerate the wispy effect of the leaves by having a wispy effect on the areas in focus. At f/2.8, one plane of focus intersects the image. I do like the effect, but it does need an appropriate subject to work.

Isolation of the one buttercup and ultra-smooth bokeh, just as I like it.

Isolation and the bokeh is gorgeous. I like the background echoes of the main colour, but they do need smooth bokeh to make them work.

There is a whole world of portraiture to explore. Here Annabel patiently poses. I use this doll sometimes as the eye detail is amazing. Shot close to minimum distance at f/2.8.

I haven't had the lens long enough to explore further, but the potential looks very exciting, and coupled with high performance in the normal focusing range this extra feature is a great bonus to have available.
