Rollei QBM mount 135mm f/2.8 telephoto with multi-coating for Rolleiflex SLR cameras.
The Rollei Rolleinar-MC 135mm f/2.8 is a telephoto prime lens for the Rollei QBM (Quick Bayonet Mount) system used on Rolleiflex SL35 and SL2000 cameras. The Rolleinar designation indicates Rollei's mid-range lens line, while the MC multi-coating provides enhanced contrast and flare resistance over uncoated alternatives.
Optical quality is good with sharp performance at moderate apertures and pleasant rendering at 135mm. The f/2.8 aperture provides effective subject isolation for portrait photography, which is the natural application for this focal length. The multi-coating delivers clean, punchy images with accurate colour reproduction.
Build quality follows Rollei's standards with solid metal construction and smooth mechanical operation. The QBM mount provides a secure, quick-change bayonet connection. The lens balances well on Rollei SLR bodies and the focus ring provides smooth, precise operation for manual focusing at telephoto distances.
On the used market, the Rolleinar 135mm f/2.8 QBM appeals to Rollei SLR system users and collectors of Rollei equipment beyond their famous TLR cameras. QBM mount lenses can be adapted to modern mirrorless cameras, giving this lens a practical second life beyond its original Rollei system for portrait and telephoto work.
