Switching from PENTAX to LUMIX – Pros | 有閑寫眞倶楽部黎明編

It wasn’t a sudden switch, but looking back on the past year since transitioning from the PENTAX K mount to the LUMIX MFT/L mount, I’d like to share my thoughts, personal pros and cons, and other observations.

Previously, my main camera was the PENTAX K-3III (K-mount APS-C), with the LUMIX G99 (MFT-mount) as a secondary camera, and I would occasionally use the LUMIX S5 (L-mount full-frame) when conditions allowed. However, around June last year, I streamlined my K-mount lenses and expanded my L-mount lens collection, and in September, I upgraded the G99 to the G9 Pro II.

Currently, the most frequently used camera is the lightweight and versatile G9proII. If I don’t need a telephoto lens and want to experiment with a prime lens, I use the S5. The K-3III is occasionally used for dynamic preservation. For a list of lenses I own, please refer to the link.

* I also use a LUMIX GF10 (MFT) as a small sub-camera, but since it is for a different purpose (as a compact camera replacement), I will exclude it from this discussion.

[Pros]

1. I can take more photos with perfect focus

There are probably three reasons for this. First, the AF performance and image stabilization performance of the camera (especially the G9proII) have improved, reducing the likelihood of blurring and camera shake. Second, I have had more opportunities to shoot with MFT, which has a relatively deep depth of field. Third, my handheld lenses have been replaced with newer models, which have improved average resolution and increased the “sharpness” of the images. I think those are the main factors.

If there is a fourth factor, it would be that my skills have improved a little over the past year… but no, that’s probably not it.

Recent examples of photos where I’m satisfied with the sharp focus.

※I don’t shoot fast-moving subjects, so I’m not really affected by the common opinion that “LUMIX has weak dynamic AF.” Compared to PENTAX, anyway (self-censored).

2. Less stress when operating the camera

Since switching from a DSLR to a mirrorless camera, the number of AF focus points has increased and the range has expanded, which is undoubtedly convenient. However, I don’t use full-area AF or tracking AF very often, so I haven’t really felt the direct benefits.

What I appreciate more is the convenience of the G9proII and S5 being almost identical in body design. Since I can set the buttons and dials almost identically, switching between the two cameras is completely stress-free. This has been more helpful than I imagined.

So, the criticism that an MFT camera with a 1/4-inch sensor should not have the same large body as a full-frame camera is valid (I actually thought the same), but lately I’ve come to accept it after weighing the pros and cons.

Since the movements of my fingers from holding the camera to pressing the shutter are always the same routine, even a perpetual beginner can improve their skill level to some extent. This allows me to focus on more important actions, such as finding the subject, adjusting the lighting, composing the shot, and deciding whether to move closer or farther away.

Another point, not related to camera operation, is the significant economic advantage of being able to share batteries between twin bodies.

3. Lighter equipment to carry

Although the S5 camera body itself is slightly lighter than the K-3III, I thought that my bag would become heavy when taking pictures with a full-frame lens, but that wasn’t the case.

For economic and physical reasons, I have decided not to shoot with a full-frame camera at high focal lengths, so when I take the S5 with me, I only bring one lens, the LUMIX S 24-105 F4, or a wide-angle zoom lens such as the LUMIX S 14-28mm or LUMIX S 20-60mm, along with a few small prime lenses. For locations where I know in advance that 105mm will likely be insufficient, I don’t even consider bringing the S5.

When I need a telephoto lens, I don’t hesitate to use the G9proII. Even the slightly heavier Leica DG 50-200 telephoto zoom lens for MFT weighs only 655g. This covers up to 400mm in full-frame equivalent, which is as light as an angel’s feather compared to carrying a telephoto lens with the same focal length in full-frame.

Local trips are also easy and enjoyable thanks to its lightweight design.
For shooting opportunities where I want to extend the telephoto range further, I have a teleconverter instead of a heavy telephoto lens. Lightness is justice.

4. The joy of updating equipment has increased

K-mount and MFT-mount cameras do not have many new products being released by manufacturers. This is not necessarily a bad thing in terms of peace of mind, but it cannot be denied that there is a lack of excitement. However, I am able to fully enjoy this pleasure with the L mount.

Leica products are out of reach for most of us, but Panasonic and SIGMA are actively supplying new L mount bodies and lenses. There is constant enjoyment in browsing magazine and web media for information on topics like “What to target and when to update the S5” or “What is the best choice for a 35mm prime lens,” and in attending events or visiting stores to handle and test products.

Additionally, L-mount (excluding Leica) products are more affordable than those from major RF, E, and Z mount manufacturers in terms of body and lens prices. Of course, this varies by product, and even if something is relatively affordable, it doesn’t mean I can afford it, but at least there’s a hope.

The reliable LUMIX S 24-105mm is an indispensable main lens.

Is it ”hope”? Or is it “swamp risk”? For those who thought of that retort, I don’t like adults who are so perceptive like you.

If I were to add one more thing to the above 1 to 4, I would say that the enjoyment of using “looks” such as Leica Monochrome and LUT has increased, but since this is something that PhotoLab users can achieve even if they don’t use a LUMIX camera, I will leave it as an extra.

Since the article has become quite long, I’ll continue with the next part, “Things I Find Disappointing,” in the next post.
