On this video photographers, Jay P. Morgan and Kenneth Morgan (from the Slanted Lens) take a look at two zoom lenses for Sony cameras – the Sony 24-70 f/2.8 GM and the new Tamron 28-75 f/2.8.
Tamron’s 28-75 f/2.8 is a very interesting lens and a great competition to the Sony 24-70 f/2.8 GM. On this head to head series of tests, Jay and Kenneth take a look at several key performance aspects of the two lenses.
When it comes to sharpness it seems from the tests that the Tamron 28-75 f/2.8 is either as sharp or sharper than the Sony on all focal lengths. The bokeh of both lenses seems very similar (and good), both lenses don’t seem to suffer from too much breathing (which is really nice).
The test didn’t seem to show if there is a difference in vinette and barrel distortion which are important given the nature of these zoom lenses.
It is worth mentioning that besides the actual performance and pricing of the Tamron’s 28-75 f/2.8 this lens is also considerably smaller and lighter than the Sony (not surprising being a 28mm and not 24mm).
