You really want to download 4x 42mp files? And the result in this case is pretty clear.... The Leica brand lenses in 35mm 1.4 format, are superior. The TTA lens is superior to the 7A lens, even though it is about the same cost and has less glass inside. In the case of the Nocti, The Leica lens is optically pretty much the same as the 7A lens. I did not expect any of these results. But there is more to this than just better or worse optically..... The reason you are considering these lenses..... There are 2 really good reasons and a lot of others.... 1) you can not afford the lens for the amount you will use it. This is my reason for testing the 50 1.1 7A lens. I used it once or twice in 10 years. I sold the Nocti and put roughly $4K back into my bank accounts. AND I did this without compromising my lens choices. A pretty good trick! 2) you are or will be in a situation that there is a fair to good chance The lens will be stolen or destroyed by what you are going to do or where you are going. Think bad neighborhoods, leaving your equipment in a hotel for a few days, or canoeing down a river. Replacing a few hundred dollar lens is maybe possible, a few thousand is not. Now maybe you are more observant / picky or otherwise have better eyes or different needs that myself, in which case my words can act as a guide that you are not being ripped off by these lenses. To give you the confidence to purchase one, test it out for yourself. See what you think...... THAT is the purpose of my writeup. To instill confidence that the lens is worthwhile to try out. FYI, the 7A 35mm f2 lens is NOT a good lens IMO. It is not worth the testing time. Note that I was loaned the 7A 35 f1.4 lens by Mark. All the others I own or owned ( in the case of the Nocti and 74 Lux) myself and paid for them at full rate. In a few months I will start to test the 75 f1.25 7A lens against the 75 Summicron ASPH. I think this will be a non- toss up. The Summicron is so good that it is hard that the comparison will not show this up pretty clearly... just as the 50 Summilux asph is clearly a superior lens to any other 50 I own. Mark gave me nothing except the loan of the lens. If the 7A lens had been better, I would have purchased one from him. I am awaiting a loaner of the 50mm F0.95 lens to test against the 7A 50 1.1. That test will be interesting......
