RED recently announced that they were redesigning the front housing on their 17-50mm T 2.9 zoom lens. The previous housing had an abnormally large front diameter. The optics measured roughly 80mm at the front whereas the housing was a whopping 144mm. This made it very difficult to use the lens for 3D work since the lenses couldn’t be positioned close together. The lens is relatively light weight, but when paired with a matte box that was able to accommodate such large front, the rig suddenly becomes quite heavy.
Well, this is proof that REd listens to their customers. There is absolutely no reason, other than pleasing their customers, to change the housing of their lens. BAM! Well done RED! The new housing is a rather common 114mm diameter and will look relatively similar to the RED Pro Prime lineup. As far as I can gather, this is how the lens will ship from here on out. RED is offering an upgrade for existing lenses for a mere $250. If you ask me, this is a great deal. The material alone probably cost close to $200 for RED. So stop complaining about the salad bowl that is your 17-50mm RED and send it in for this upgrade.
