Panasonic vs Olympus : 15mm vs 17mm, 42.5mm vs 45mm

Jumped back into M43 recently and realized how compact the whole system can be, so I want to round out a kit of primes.

I already have the 25mm 1.7 Panny.

I need a prime that's wider, and one that's portrait length, so it's one of the above lenses. I have an OMD EM10ii.

The 45/1.8 has a field that curves towards the camera at the edges, increasing the background blur. This is a plus if your composition has background at edges, e.g. a portrait, but  may be undesireable in other compositions.

The 42.5/1.7 has a flatter field.

The 42.5 has OIS and the 45/1.8 does not. This may or may not matter dependng on the camera you are using.

Oh, didn't know that about the Oly lens. That's actually a plus for me as probably 95% of usage of such a lens would be portraits.

The 45/1.8 gives nice background separation for portraits, and good color and contrast. Also focuses quickly and silently. My main quibble is it does not focus particularly close.

Since you have a 25, the 15 would make a more distinct change from that than a 17. It also happens to be very sharp, although more expensive than the 17/1.8.

Good luck,

Rick

If you aim to shot portraits, then I suggest the Oly 45 f1.8 all above. It has a very nice image quality, and smoother bokeh than the Panny 42.5 f1.7. The Panny is more like a general tool with OIS and shorter minimal focus distance, however, it has harsher, and swirly bokeh. So as a specialized portrait tool, the Oly is better, no question.

I think the 15mm makes more sense if you already have the 25mm. However, I would also consider the 14mm f2.5. I like that lens a lot, it has a very nice rendering, and I like the FOV, too. It has a very flat profile, so your camera became really small with it, and it is also much cheaper than the 15mm.

I had the Oly 45 f/1.8 for quite a while but sold it after I acquired the 42.5 f/1.7 as part of a package deal. I took some shots with both lenses and thought the IQ was nearly identical, including the quality of the bokeh.

To me with Panasonic bodies, it came down to the 42.5 offering DFD autofocus and working with Dual IS on my cameras, neither of which work with an Oly body. The 42.5 also focuses closer and it comes with a hood and pouch, unlike the 45, so those items benefit any user.

Unless the closer focus distance matters to you or you think you might someday get a Panasonic body, I'd say buy the one that costs less.

For someone with a Panasonic body, I would recommend the 42.5 over the 45.

I use the 15 and the 45 on my EM10ii. All silver! Classic looking, very compact kit, and very good results. I don't use the 45 that often, but it is tiny, inexpensive, fast, and sharp (in the center, where it matters!). Agree with Rick on the minimal focusing distance, that's a bummer, but can be fixed with a macro tube if needed.

15 vs 17 is a bit of a toss-up. Each has a number of strong points, and I'd use (and have used) either one just as happily.

17/1.8 has similar problem, not that sharp on the sides with visible field curvature.
one more option for 42.5/1.8 - YI lens: cheap, sharp, good for close ups.

IMO the 15 and the 42.5 are the better lenses of the ones you listed - and I'm mostly an Olympus person.  Sharper, better rendering, etc.

Peace.

If you really want a portrait lens, I would recommend the Sigma 56 f1.4. Since acquiring it, I rarely use my 42.5f1.7, 60 f2.8 or 75 f1.8. Delivers similar quality to 75 f1.8 at a fraction of the price and a more usable length (close to classic full frame 105mm).  In terms of broken, because of

That Sigma 56mm f1.4 is really good/  About as sharp as my Oly 75mm - and that's SHARP!  I don't have any pictures to show right now, but I think you'd be hard pressed to tell which lens took what picture in a comparison.

Peace.

All four lenses are good, but the two Pana options are sharper to the edges wide open, if that matters to you. The 17 is also a little soft overall but unless you look for it, not really a problem.

Agree in general but the difference is really small (I suspect very close to sample to sample variation).

I found a surprising difference between Oly 17/1.8 and PL 15/1.7 which nobody seems to mention - I like Oly's color rendition much better. It's a subtle but noticeable difference - Oly has normal tonality with a bit more vibrant colors while PL has more cold palette. Maybe it's Olympus in camera processing tuned specifically for this lens but I was not able to replicate Oly's colors in post processing of PL's photos.

Sharpness vise there was no difference between the lenses in the center - my copies were both sharp. PL was slightly sharper in the corners but I had to pixel peep to confirm that. I needed the lens for citiscapes  mostly, so I sold Oly but I'm still missing it's colors - might buy it again, especially that it could be had below $200 used now.

I don't think so. I did not have these lenses, but in review comparisons between the 15mm and the 14mm f2.5 it seemed to me that the 15mm's pictures always have a colder look. That strengthen the suspect that it has a colder color palette. Whether you like this or that is more like a matter of taste.

This also means that you could try the 14mm f2.5, since it has good colors and IMHO a wide enough focal length for cityscapes.

but I was not able to replicate Oly's colors in post processing of PL's photos.

Re: Panasonic vs Olympus : 15mm vs 17mm, 42.5mm vs 45mm

I've had copies of the 17 f/1.8 and PL15. The Olympus was capable of making very nice images but as a prime it was not a standout in terms of resolution. My copy of the pL15 is distinctly better than the copy of the Olympus 17 I owned. Especially wide open. Both excellent mechanically. Aperture ring on the PL is a plus if you're using Panasonic bodies. It doesn't work on Olympus bodies. I have the Olympus 45 f/1.8 which I've been very happy with in terms if IQ. Very small, light, and inexpensive. Feels a bit cheap but I think it's very good optically. The Panasonic 42.5 has a very good reputation. If using a Panasonic body the ability to use dual stabilization would be a plus.
