![]() But you still have to consider point 2 below.Ģ. that final diameter will make circle of confusion (bokeh balls) getting bigger chance to look like a bokeh ball. simply divide focal length with f number and you get lens diameter (30/1.4 < 50/1.8). the focal length must be taken into equation for the bokeh quality. smaller F number doesn't always make better bokeh. Some facts (unscientifically though) need to be considered when talking bokeh:ġ. Also, I have no interest in needing a lens specifically for portrait shots. Do folks think that might be a better lens for bokeh given wider aperture? I would only want the 50mm f1.8 or 30mm f1.4 so would love input on which is best for bokeh shots. I am also interested in taking night time shots that have cool effect of blurry city lights in background, but have not done yet. It produces great bokeh effect when I've done close-up shots of flowers. I'm a beginner with Sony a6000 and 50mm f1.8 lens. The Sony FE 85 f/1.8 is very high on my personal wish list, and my Sony 50 (which I like, but rarely use since I got the Sigma 30) is probably going to get sold to get me closer to getting that 85. There is a limit to low light focus, but I haven't noticed a huge difference in abilities between it and other lenses I have. Great sharpness, fast AF for stills, creamy backgrounds when subject is close. On the Sigma 30 f/1.4, I've got one and I'm stupid happy with it. Longer is better, although longer + wider usually mean more money. +1 what he said about focal length effecting bokeh. Conspiracy theories say that it is almost identical to the Batis 85 and image quality seems to be equal from what I have seen. If you are looking for strictly a portrait lens then maybe consider something a little longer and fast like the FE85/1.8 when is getting a great reputation for an inexpensive lens with great image quality. I'd suggest something in 50mm or preferably longer (for apsc, 75 or longer on ff). You will probably find that the compression of a slightly longer than normal focal length will give a very flattering/pleasing effect. Try a 30, 50 and 80 at f4 and watch what happens to both bokeh and perspective. The longer you go the shallower the depth of field and the more extreme the bokeh is for any given aperture. Keep in mind that bokeh is not just affected by aperture but also focal length. At 135 or longer on apsc even f4 will give good bokeh. When shooting longer you don't need crazy fast. I also will use my 80-210 zoom for portraits. Personally my portrait lens is the 55/1.8 Zeiss (ff lens on apsc body). The focal length of 30 is also a little short for flattering portrature. Really sucks for the model under that kind of heat. I had to turn my modeling lights to full in the studio just to get it to stop hunting. I had one and optically it was great but AF was a total joke. Overall, I think it's a good combinaison to have both lenses, the 30 is also quite cheap for a 1.4 lens and it's a better "walk around" lense. The Sigma 30 F1.4 is more polyvalent than the 50, which is more specialized for portrait.īut the bokeh of the 50 is hard to beat, and I don't think you will have better result with the 30 for bokeh.
