Been after this lens for a while and have never seen it anywhere near this price!
I know Olympus has just released a 30mm Macro lens which is currently around the same price, but this one is arguably a more useful focal length, and has a lot more features such as a distance scale, magnification indicator, focus limiter, brighter maximum aperture and comprehensive weather sealing.
It usually sells for around £400, and according to camerapricebuster the cheapest it has ever been is £274.
Taking advantage of several Black Friday offers it can be had for under £217 -
Park Camera price - £365
20% off with code BF-OLY-LENS20 – brings it down to £292
75% Olympus cash back brings it down to £217
Plus a free Sandisk 32GB Extreme Pro SD card worth £31.99 (£19.99 on amazon to be fair) with orders over £300 (this still qualifies)
