![]() ![]() Losing the excellent a7ii + 55/1.8 combo (if I stick with this switch) is gonna be hard to get used to. It is not as fast to focus as is the Sigma or my other m4/3 lenses, but its not slow, either. I'll give it an honest shot in real-world use before complaining too much more. The sigma 30mm f1.4 you mentioned is a v nice lens. Yeah, I think my expectations were just a bit too high after the rave reviews. Perhaps some of the reviews set our expectations too high with grandiose statements like "perfectly sharp across the image when wide open". It was far from perfect in the sharpness uniformity department when wide open. I got the Sigma 16 and had it for a while, then returned it due to the f2 focusing bug. Loss of contrast is more pronounced than loss of resolution as you open up. Huh, I've had no issues with the EVF so far (it's similar in sharpness to the a7 ii's, and faster too with 120Hz refresh). No one like seeing their face full of crows feets, and acne pot scars./ Maybe you have slightly mis-focused?Īlso sharpness isn't everything when it comes to portraits lens. Sony 35mm 1.8 OSS (which I used to own) is much softer at 1.8 than Sigma at 1.4.Īs much as I am impressed by A6400 AF speed and rapid response, I'm let down by the Tiny Dim Dark EVF that feel like peeping through a keyhole. You should expect a bit less contrast at 1.4. ![]() Take into account limited depth of focus at 1.4 and some field curvature. It looks very sharp to me in the center, where the focus point is, just like my copy. If I have to use this at or below f/2-ish anyway, should I instead consider switching to the stabilized Sony E 35mm f/1.8 instead? Or will that be similarly not-sharp wide open? Here is a sharpness comparison starting from f/5.6 going to f/2.8 to f/1.4: I recently switched from the a7 II to the a6400 (for size/weight, and autofocus reasons), and I knew I would possibly have to make compromises in image quality - especially considering the excellent Sony/Zeiss 55/1.8.Īfter reading the rave reviews of the Sigma 30mm f/1.4 DC DN Contemporary lens I decided to get one, but I'm not fully satisfied with the wide-open performance, or maybe I'm just being too picky and comparing it to a legend. Nothing in the world is really perfectly parallel to the sensor ever, so out in the world you will have to decide which mini-slice you want in focus at f/1.4. Get out and photograph, even dare to use f/1.4 when there is a need. Do you have an optical bench with micro adjustments? If not, all your tripod work will fail you miserably and give you a false prejudice and dislike of this lens needlessly, I am afraid. I can see the misalignment very clearly at all apertures in your pics. You need to have microscopically and accurately aligned and absolute parallel planes that you depict and what the sensor depicts. If you had checked this out, you would realize that your skewed alignment throughout this new trial is responsible to your seemingly lack of focus results. Have you taken the time to find the actual DOF at f/1.4 for your lens and distance? What is the actual DOF here, in millimeters, please, and do let us know. ![]()
