My brother Alex is my worst enabler. I now want a Rolleiflex after trying out his Rolleicord recently on a hike near Belfountain. For those not familiar, Twin Lens Reflex cameras have been around for about 80 years and use 120 roll film. The Rolleicord is the prosumer TLR derived from it's "big brother" the Rolleiflex and differs a little on features and ergonomics.
So why beat around the bush, get the rolleiflex and be done with it. As much as people merit the versatility of a Hasseldlad 500 series 6x6 SLR system, personally I rather have the TLR. You only get one choice of lens on the camera as it is built in, mechanically it's really simple and it does not weigh a ton. What I love about medium format photography is you have to slow down, plan your exposures a lot more than 35mm and be really fussy with your metering of the scene.
I used Ilford Delta 400 black and white film processed in Xtol 1+1. Not my usual choice of film, it's all Henrys Oakville had in stock. I prefer Ilford HP5 or Kodak Tri-x 400 for their grain structure, I like a retro look to my images.
