Panasonic 100mm/2.8 Macro


Recommended Posts

Very small! I used to have the 100mm 3.5 Canon RF lens. Now that is a tiny telephoto!! I am sure this one is quite a bit better, however.

Looks awesome, wonder if Leica will do a rebadge of this.  The SL lineup is sorely lacking a macro 1:1 option.

A Leica macro has been rumored for quite some time. It could be based on this lens, hard to say. Previously, I was thinking of a Leica-version of the Sigma 105 macro, but the Pana is possibly more likely. Will be interesting to see; perhaps a launch together with SL3 during the following months?

I asked myself if there really was any need for this lens since Sigma already offers the superb 2.8/105 Macro in L-mount. It looks like what really speaks for the Panasonic lens is its extreme compactness and low weight. Looks like good optics as well. Which one will Leica rebadge? Who knows, but I certainly expect one of them. My guess is the Panasonic.

Just as your own thought, the big advantages as for the new Panasonic lens comes to compactness and low weight.
(More than half of the weight of a Sigma lens).
Another big advantage over the Sigma could be the absolute minimum traces of focus breathing, for stacking images to get more wide DOF.
All these advantages if doing 3D macro photography "in the field".

When doing studio photography, and e.g. "flat field" reproduction photography, weight and compactness is less important.
Within this field you do want a very high quality from corner tot corner.
Comparing MTF curves, the < Sigma > still do have an advantage over the < Panasonic > macro lens.

A specialised 1:1 test of the Sigma 105mm macro lens and e.g. Laowa 100mm macro can be found by a user
who always is looking to the highest standards as for macro / micro photography.
Comparing "industry process" lenses (e.g. Printing Nikkor and Nikon "Rayfact") to all kind found old and new lenses.
(Scan-lenses - enlarger lenses, etc.....).    Photographing a "chip wafer".

It is not to be expected that the new Panasonic lens shall be tested as well by this person. (He don't own an L-camera).
But at least an interesting website IMO.

If the optical performance is similar to the Sigma 105, the Lumix 100 could replace my Sigma Macrolens. The low weight and compactness is a benefit, if one carries various lenses around. If you go shooting especially for Macro, weight and size isn't that important. There will come some comparison reviews between the mentioned lenses for sure.

I appreciate Panasonic is extending their S-line and I am looking forward for more S-lenses and S-cameras from Panasonic.

Looking at the MTF, the performance looks to be very good, but not as good or as even as the Sigma. As always, there seem to be trade-offs. A bit of optical performance for a smaller size. But I think that for the majority of users this is probably completely fine. Especially for those who are looking for a more general purpose lens...especially those with the SL2S or S1/S5 models. With the SL2 and S1R and a newer higher MP body, you will likely see more difference. The MTF tests shown are for 10 and 30lpmm, and the Panasonic looks great at 10lpmm but loses a bit at 30, which suggests that it has a lot of contrast, but starts to lose a bit of fine detail, particularly towards the edges. The Sigma's 10 and 30mm are closer together and more uniform, which suggests to me at least that it will hold up better on higher resolution sensors. I want to emphasize though, this is not a contest...this is about choosing the right lens for your needs. The Panasonic looks great and what it can do in that body shell is pretty amazing.

I bet on the Panasonic. It has the same form factor and size as the other lenses in the lineup. Meaning that Leica has the metal outer shell ready from the rebadged Summicrons.

Oof. I wish they would just make their own, but maybe that is pointless. Still, the 100mm APO Macro Elmarit R and 120mm APO Summarit S are among the very best lenses in their systems, both of which were known for the superiority of their lenses to other systems. Those lenses are still incredible...it would be amazing to see what Leica could do now...

Agreed, but there is also the question of affordability. I owned the Apo-Macro 2.8/100mm many years back. At the time, there was nothing like ut. I have not seen any comparisons, but I expect todays macro lenses such as the Sigma 105mm to match it. A comparison would have been interesting.

I used to have it, but sold it when I went into the S system. I currently have the 120mm APO and 105mm Sigma, and optically the 120mm is just slightly better, but it was originally almost ten times the cost. I think the 105mm Sigma is likely to outperform the older 100mm APO in terms of sharpness, but I imagine it would be very close. As for bokeh and "feel", I think that is more subjective and would basically come down to preference. I loved the 100mm so much at the time, that I would probably give it the edge, but as I have said, I have not had a chance to compare. When I compared the 105mm to 120mm, the Leica maybe looked a bit better in some very small ways (out of focus specular highlights were more natural...the Sigma had more of a ring/donut effect), but these were differences that were only visible in very detailed comparisons. Both were exceptionally sharp and free from color fringing and bokeh fringing. The Sigma has the advantage in being much cheaper, lighter, faster focusing and focuses natively to 1 to 1. The 120mm has the advantage of working on medium format, better manual focus, longer working distance, and more solid build quality. But it does not make sense as a lens to buy just to use on the SL bodies...if you have it, by all means use it and enjoy it, but it is kind of overkill to buy to use on the SL in my mind.

This seems much the same story as Panasonic's other f/1.8 lenses, although I'd question whether the optical performance loss is just 'a bit'.

A bigger puzzle, though, is that Panasonic's 100mm macro lens is more expensive that the 105mm from Sigma, yet the latter has had rave reviews and the MTF curves suggest it should be the better performer. (The f/1.8 lenses are notably cheaper than other manufacturer's lenses).

Yet, the Sigma is still cheaper. I am considering a macro lens, thought it would be the Sigma, but now I really want to see real life results, as I don’t understand the charts…

You can learn about the basics here. https://www.nikonusa.com/en/learn-and-explore/a/products-and-innovation/what-is-a-lens-mtf-chart-how-do-i-read-it.html

The basics are that when you are looking at an MTF chart, the Y axis (up and down) is the percent out of 100 of contrast. 100% contrast = a perfect lens...rendering detail exactly without any optical loss. This is impossible with real lenses. The X axis (left right) is the distance from the center of the frame, usually in mm. The different lines are sagital and meridonial lines...basically lines parallel and perpendicular to each other. These are references for detail. Their size is calculated by "line pairs per mm". So basically how many of those lines you can fit in a mm. Most companies measure 10 and 30lpmm, Leica does 10, 20 and 40lpmm. So the lines going across the chart are to what degree of contrast (i.e. how sharp) the lens can define those lines. So when you are looking at a chart, the closer to the top, or 1 on the chart, the sharper the lens. Additionally, the straighter the line across the x axis, the more even the sharpness. A perfect lens would be straight lines across the top. It is pretty quick and easy to read them once you get the hang of it, and it is a helpful guideline. You just need to make sure you are comparing the same thing...the same distance, same aperture, same lpmm etc. Usually companies just provide wide open at infinity. Leica usually provides several apertures at infinity and close up. 

In the case of the Panasonic and Sigma, you can see that the Sigma has a sharper performance across the frame than the panasonic based on the charts they publish. There are other factors that are important as well, of course, such as chromatic aberration, distortion, vignetting and so on, but MTF gives a good idea of sharpness (and some other things if you go deeper into learning about them).

As a rank amateur I find most of the current L mounts are more than good enough and I choose on size, weight, weather sealing, 'look' and feel and of course cost is in there somewhere too.

I've ended up trying and passing on an awful lot of Sigma and a few Leicas lenses to end up with almost exclusively Panasonic S lenses with just the one S Pro

Having let both the Sigma 70(irritating ext zoom) and 105(too big and heavy) macros go I will undoubtedly pick one up in preference to a heavier Leica version at 4 times the cost, and to me at least, less attractive than the Panasonic.

Already noticed by MTF differences Lumix 100mm macro lens versus Sigma 105mm macro lens.
The Sigma lens do have the advantage as for optics.

In meanwhile other testing / reviews are published.
You can make a comparison by same lens testing methods used for Lumix lens and Sigma lens.

The quality of the Sigma lens undoubtedly is the best choice as it comes to "optical" characteristics.
And in line what an  independent user photographing “micro chip wafers”  experience found out for the Sigma lens as well.

Cards are shuffled again.

Interesting, but other reviews have been a lot more positive. Here it is said that optical performance is disappointing, but there is a qualification as the tested lens is a pre production sample and hopefully lenses from regular production are better.
