Panasonic 25mm f/1.7 lens review

Hello all! Here’s my review of the Panasonic 25mm f/1.7 lens. I LOVE this camera lens and use it most of the time on my Panasonic GX85 camera when shooting photography and video (now my main camera.)

For those not too familiar with photography

There are two types of camera lenses; zoom lenses and prime lenses. Zoom lenses allow you to zoom in and out on your subject and are more familiar to most people. Prime lenses have one fixed piece of glass so no zooming is possible. The trade off is sharper images with prime lenses.

Zoom lenses come in handy when photographing events such as sports, weddings or wildlife. Since I don’t photograph or film much of those anymore, I started using prime lenses only. Prime lenses have become my favorite lenses for a few years now.


  1. Prime lenses have a fixed lens (no zooming) and only one piece of glass, which makes them less expensive.
  2. Prime lenses take razor sharp photos! Sharper than zoom lenses.
  3. Prime lenses take better photos in darker areas, are lighter and focus quicker.

I used to have the popular Canon 70mm-200mm F2.8 L series lens. I used this zoom lens on my Canon 5D MarkII and loved it very much. I paid $2,000.00 for it new: worth every penny. I sold it when prime lenses were all I needed once I stopped photographing weddings. It was difficult for me to part with this lens. The photos shot with this lens were always perfect. Sharp, nice color and warmth to each image, is what the Canon 70-200 provided.

Now that you know the difference between zoom lenses and prime lenses, let’s talk about the Panasonic 25mm F1.7 prime lens. It’s a lightweight very fast lens that takes great photos and video. I highly recommend it.

Check out this video I made reviewing my Panasonic 25mm F1.7 lens.

One of the main things I take into consideration when buying a lens is the focal length, which is that number followed by mm. The smaller the number, the wider the view of the lens. The larger the number, the more zoomed in the lens will be to your subject. If you were taking portraits, you would want a 25mm or 35mm. If you were photographing a lion at the zoo, you would want a longer focal length, so a 200-400mm would be best.

The issue with prime lenses is you need to carry a few if different focal lengths are needed. I chose 2 focal length lenses that suit me best and I’m fine. For anything else, I use a pro camera with zoom such as the Canon PowerShot G7 X Mark II.

A 50mm lens is said to be the perfect all around lens for photographing or filming video. 50mm has the view of what you see as a person, or, how close you are to a subject. This would be the equivalent of a 25mm lens on a micro four thirds camera, such as my Panasonic gx85. Micro four thirds cameras register at half the mm rating of a DSLR, or, old school 35mm film camera. So, my Panasonic 25mm F1.7 lens is equivalent to a 50mm standard lens.

The next thing I look at is F stop setting. In this case, the F stop is 1.7. The F stop setting is one of the ways you can control light into the camera and also the “blurriness” behind your main subject (depth of field.) The smaller the Fstop number, the better the lens is at taking photos in the dark. Smaller number Fstop – rated lenses are called FAST LENSES because they see well in the dark and are very fast at capturing images without sacrificing quality.

I know it sounds confusing and that’s because it is. Trust me, the more you work with Fstop and focal length and shutter speed, you will find out how it all works together, resulting in great photos.

Panasonic Lumix G H-H020 20mm f/1.7 Aspherical Pancake Lens for Micro Four Thirds Interchangeable Digital SLR CamerasI almost went with the Panasonic 20mm F1.7 lens to get a bit more width in my photos. This lens has been dubbed the pancake lens since it’s flatter. Since I already have the Panasonic kit zoom lens that goes from 12mm, I already have a nice wide angle, so the 20mm wasn’t needed. I wanted the 25mm for the feel of a true 50mm lens.

Does this help you in choosing a lens? I hope so. What lenses do you have? Let me know in the comments and check out my YouTube channel Rotter Studios for more photography and video tech stuff and projects.
