flare control: 4
|ownership:||I own this lens|
|compared to:||Min 24/f2.8 (RS), Sony 100/f2.8 Macro|
|price paid:||149 GBP|
|positive:||Compact, sharp, cheap + you will bump into things before you are too close to focus on them.|
|negative:||Horribly light off the camera. Front element quite exposed (not recessed).|
|comment:||Amazing little lens - could be as sharp as the 100 Macro and will never refuse to focus on anything - you will give up before the lens does.|
Tested on a full-frame film camera, where the image circle filled the entire viewfinder - looked like there was some darkening in the corners, but still very usable.
Double extension is very robust, without wobble and the front of the lens does not rotate (so OK for polarising filters).
Front element is not recessed and there is no lens hood, so I've ended up screwing an empty 49mm filter ring on the front to give a little protection and to allow the fitting of the lens hood from an old 28mm Takumar (although the hood has to be removed for close-ups as the lens focuses so close).
DMF does not work with this lens - similarly the AF/MF button on the a700 body will still work, but the lens is not released. The on-lens AF button is a positive asset on the 5D, where it falls to hand better than the body switch.
Although the lens is very light off the body it seems quite well put together and you don't notice the absence of substance when it is attached to a camera body.
Lovely little lens - a treat to use - a new 'plastic fantastic'.
