Lens testing at Quiapo
After concluding that 50mm is far too narrow for practical freelensing, I eventually headed to Quiapo to hunt for a prime lens with a shorter focal length. It was in one of the unnamed shops where I stumbled across the smc PENTAX-M 1:2.8 28mm.
Hailing from the late 70's/early 80's, this was a lens with a solid build but less than stellar sharpness (according to the reviews). Fortunately, sharpness isn't as significant a factor with regards to freelensing.
While waiting for my other equipment to be serviced, I spent half an hour roaming the vicinity to try out this new(ly-purchased old) lens. Quiapo's crowded and cluttered streets were perfect for testing the potential of this lens for isolating detail.
It's far from being an ideal tool for street photography, but with the right technique, this lens can do wonders for portraits.
