Let’s see if the new Yongnuo 25mm f/1.7 lens (Amazon US, Amazon DE, Amazon UK, Amazon FR) is a match for the Panasonic!

Dpreview added the GH5 II to studio test scene:

At base ISO there’s no appreciable difference between the GH5 II and the original version. There’s a slight improvement in apparent sharpness, but this is likely to be due to the use of a more expensive lens on the newer model. As with the original GH5 there are hints of moiré, which makes sense, given the absence of an anti-aliasing low-pass filter.

At very high ISOs there appears to be a slight ISO advantage to the newer camera, but it’s not sufficient to make a visible difference at lower ISOs. The JPEG engine appears to be tweaked a little to hold onto a little more detail in low light, though.

There’s not enough of a difference in color response for us to conclude whether this has been adjusted, though there’s a hint of the more muted caucasian skin tones shown by the GH5S. Overall, then, not much difference you’re likely to notice in day-to-day shooting.

Delving a little further in dynamic range, in our exposure latitude test, the deep shadows of the GH5 II’s files look a touch noisier than those of the existing camera, which contradicts the numerical assessments made by DxOMark and PhotonstoPhotos. This could be the result of mis-calibration of the black point in Adobe Camera Raw, which doesn’t expect you to use the extreme deep shadows of images (ie the last few stops of dynamic range), but we’re not seeing the improvements reported when we look at the images.

This is a review of my Panasonic GH5 MK II. The GH5 mark 2 is a micro four-thirds mirrorless camera designed for video use and for photography. This video will cover the 5 things I learned about the Panasonic Lumix GH5 MK II before I destroyed it accidentally. Additionally, I will show you the low light performance of the Gh5II versus the GH5 and GH5S at the same ISO values. Timestamps and links are listed below. This video is not sponsored so if it’s helpful please leave a thumbs up.

I’ve been shooting with the Panasonic GH5 MK II for the last few weeks and there’s a lot to like about it when compared with other MFT camera systems. This video will showcase Vlog-L, 10bit 50p/60p, color profiles, slow motion, and much more.

Panasonic has drastically improved their Autofocus in the Panasonic GH5 MKII over the original GH5. The new GH5 2 is far better than the original GH5 and is now on par with the Panasonic S5 when it pertains to face-detection AF.

ePhotozine published the full Olympus M.Zuiko 8-25mm review and concluded:

This is a versatile lens indeed, performing well, nice and compact and at a reasonable price, making it a strong contender as a go-to travel companion. The close focusing is a bonus.

The only limitations are really relating to the small MFT format, which is by its nature diffraction limited. This shows clearly in the results, but as long as the lens is kept to f/8, possibly f/11, or faster than the images are very crisp.

Depth of field is another issue, and the lens will not be for those who seek defocused backgrounds at wide apertures. There is too much DOF in the MFT format for that. Conversely, those who desire as much DOF as possible will be highly satisfied.

Highly Recommended.
