Camera: Sony A6000 Use: Portrait, cosplay, product photography Comparison with: Sony 50mm F1.8 (same price range) Summary: + Sharpness!!! + Price + Small size and lightweight +/- Autofocus +/- Chromatic aberration - No cons The 35mm is not my first K&F Concept lens and it won't be the last either as I am already turning my attention to the 24mm lens the same type. Having been very happy with the 12mm from K&F Concept on my Sony, I couldn't wait for the 35mm and it hasn't disappointed me at all. But on the contrary. For just under 200 euros, it absolutely exceeded my expectations and I am convinced that I will not find anything comparable in this price range. I mainly shoot portraits and cosplay and an aperture of F2.8 works very well in this range. However, I have often taken my camera and lens with me to work to photograph the products. Why? Just like the K&F Concept 12 mm, the small lens is an absolute miracle of sharpness. Of course, many portrait photographers want to compensate for skin imperfections. I, on the other hand, place a lot of value on sheep to emphasize details like freckles and to achieve a kind of "cinema poster effect" in cosplay photography. Viewing the skin details on PC afterwards was a real pleasure. Every little detail is captured here. You could also count the fur hairs in the focused area on my dog. Compared to my Sony 50mm F1.8 lens in the same price range, the K&F Concept produces much sharper images that are a lot of fun to look at and edit afterwards. The small size and light weight also make it much easier to use. Since I usually go out with several lenses, it is a relief not to have to take a large backpack just to accommodate the K&F Concept. For everyday wear or an outdoor session, it's perfect. The housing also seems robust enough for normal use, but of course it cannot compete with 1000 euro lenses here. But it doesn't have to be, because if you treat your equipment with care and store it in the case supplied, you will certainly enjoy it for a long time. The K&F Concept's autofocus works reliably, but does not have a 100% hit rate. Still, it's a lot better than that of my Sony 50mm lens, which often misses the point. Since I mostly use the manual focus and only use the autofocus for self-portraits, it doesn't play a big role for me. Here maybe 2-3 out of 50 selfies are not properly focused, which is a rate I can live with very well. The focus also works much faster here than with the compared Sony lens. I expected chromatic aberration to occur at a price of just under 200 euros, but it is much less than with the Sony 50 mm. This is not noticeable in most portraits, but if you photograph landscapes more often, you can see a slight purple/green edge on trees that are in the out-of-focus area. However, it is so small that it can only be seen when zooming in and can be removed in post-processing. I can only recommend this lens to hobby photographers who want to get as much out of their pictures as possible with little money. It has become my favorite in cosplay photography in just a few months as I value sharpness and lightness here. The first attached image shows how sharp the K&F Concept is and how much detail becomes visible later when zooming. The second image shows the minimal chromatic aberration that can be seen in the background when zoomed. All images are cropped at 80-100%.
