Recently I bought 35 Summilux-M 1:1.4/35 asph fle lens. I used to own 35 summicron lens before this I liked it a lot. The only reason I had to buy summilux version of 35mm is I needed a bit more bight lens as I shoot under low light conditions often.

To my satisfaction, I was over the moon when I used it under low light condition. Not only it is bright enough to meet my expectations but also it is extremely sharp yet overall photo feels very soft, more like warm feeling as opposed to cool.

Now I am ready to shoot cherry blossom flowers with this new buddy.

Just the way I imagined, it produced transparent, clear, and sharp cherry blossom flowers. Thanks to the clear blue sky, cherry blossom flowers shine by far. Now I wondered how portrait photos will turn out.

If I use wide aperture, due to shallow depth of field, it makes photo a 3D look, which is perfect for a portrait shoot. I liked summicron 35mm, but summilux version of 35mm is like a monster. No comparison with cron.

Also I noticed that it has less distortion on the end edges. Both portrait and landscape purposed, I am certain that 35mm summilux will be my best companion for long.
