So, I almost completed my dream lens line-up by now. At least I got the cores covered with my 12mm Touit, 24mm Sonnar and 50mm Touit. So with these lenses, I got a little used to an extremely high image quality standard, and I want the rest of my lenses to be of similar quality. So which lenses do I still want? For one, a fisheye just for some special purpose shots. I will buy the Rokinon 7,5mm at some time to fill that gap. For the long end, the Sony 70-200 f/4 will do fine. But for extreme low light situations, I'm not sure yet. What options are there?

The SRLmagic 50mm f/0.95 is simply not a good lens - it's a re-used design of a CCTV lens. The SLRmagic CINE LM 50mm T/0.95 definitely is the best lens of the bunch - it even rivals the mighty Leica Noctilux 50mm f/0.95. But it gets no longer produced and even back then when it was it retailed upwards from €3000. It's virtually impossible to get now. This leaves four contenders in this race. To summarize, the contenders are the following lenses: Mitakon 35mm f/0.95 ' 680g ' €650 Mitakon 50mm f/0.95 ' 737g ' €750 SLRmagic HyperPrime CINE T/0.95 ' 800g ' €1000 HandeVision IBELUX 40mm f/0.85 ' 1,2kg ' €1500 Now to the obvious downsides of these lenses. The HyperPrime is a CINE lens, meaning it is optimized for video usage. This leaves the lens with a focus gear ring - not the most convenient focus mechanism to use by hand. Also, it has a clickless aperture, which is not too bad but still. The IBELUX seems to be the lens with the best quality control, but at the highest price and almost twice the weight of competitors it's a hard sell. Both Mitakons seem okay-ish, but I'm not yet sure about their image quality. What are your thoughts about this topic? Do you own one of those lenses? And if not, which of the lenses would you consider to buy and why?
