Sigma 20-200 review & comparison with Lumix 14-28 & 24-105

[GeorgeHudetz]

It’s unclear to me how important dual stabilization is at very long focal lengths - the conventional wisdom is that IBIS become less effective at long focal lengths, so perhaps out at 500mm it’s mostly OIS that does the heavy lifting. I’ve been experimenting with the Sigma 500/5.6 and have captured a couple of decent shots at 1/15s, but I need to do more shooting with it.

Of course, the 100-500 and 70-300 have “intermediate” focal lengths where perhaps dual stabilization is more important. No sure.

Overall image quality

Thank you so much, Paul, for such a thorough comparison. These are the photos I've been waiting for... I think your comparison confirms my belief that the 24-105mm f/4 is the best Lumix zoom lens for landscape photography, as everyone says it's an excellent lens... and if I was almost 80% convinced it would be my next purchase, now I'm 100%

Just one question regarding overall image quality: is the new Sigma 20-200mm significantly better than the Lumix 20-60mm?

Yes, the 24-105 is an excellent lens. It's been my main landscape lens since I got into Panasonic FF. I have no hesitations in recommending it. But it is quite big & bulky for the focal length on offer.

Just one question regarding overall image quality: is the new Sigma 20-200mm significantly better than the Lumix 20-60mm?

Not in my opinion. I think the 20-60 is every bit as good as the 24-105 (at least with my copy). If I had to put them on a scale, where 0 = my crappy old OM 135mm f3.5 (it's awful) and 10 = my Sigma 105 f2.8 macro, then I'd rate the IQ of L-mount lenses I've used or owned as follows:

10 - Sigma 105mm f2.8 macro, Sigma 35mm f2
9.5 - Panasonic 50mm f1.8, Sigma 70-200 f2.8
9 - Panasonic 70-200 f4, Panasonic 24-105, Panasonic 20-60
8.5 - Panasonic 14-28, TTArtisan 11mm f2.8 FE, Sigma 16-28, Panasonic 16-35
8 - Sigma 20-200, Panasonic 70-300 (when it focuses!)
7 - Sigma 100-400
5- Panasonic 28-200

I guess 8/10 is my cut off for IQ!

Thanks for another great review! I use tripod 99% of the time, so it would certainly be an interesting lens for me

Yes, for tripod use, its two biggest limitations (no OIS, small max aperture) are not a factor. I think the IQ is good enough for most people's needs, even if it's not going to win any awards for being the sharpest lens in the system.

And I'm finding that the IBIS does a decent job anyhow if you need to handhold. I shot some images yesterday evening in fading light with the S1Rii and got plenty of sharp images at 200mm and 1/20s (see image below). In fact, even at 1/3s, I can get about 50% of the images sharp at the long end. I'm happy with that.

Overall this looks like a pretty good show. I'd even say it's impressive for a super-zoom, especially one that goes this wide.

As for comparisons with the 20-60mm, I think there must be some poor copies out there because my 20-60mm, and my original one which was swapped after I discovered it had blue fogging, performs superbly at all focal lengths. It has absolutely no problems with sharpness and the only reason I don't use it more is that it lacks speed, so I use the Sigma 24-70mm f/2.8.

Lenstip have done their usual comprehensive test and it more or less confirms what I said above. Overall they like it and think the compromises have been well managed.

After you have used this for some time now, do you expect to keep your 24-105? And what is your real world experience using IBIS only up to 200mm?

The 24-105 has sat on the shelf since I got the 20-200. Stabilisation at 200mm is acceptable, but I have a steady hand and I take several to make sure one is sharp. I think I can get sharp images down to about 1/15s at 200mm, or and 1/8 with a worse keeper rate.

I think I’ll be selling the 24-105. No point It gathering dust on a shelf.

No point It gathering dust on a shelf.

Thanks. I am starting to get GAS about the 20-200 as a travel lens. Along the line of carrying less lenses for travel I'd also try for less lenses on the shelf. So I'd sell the 24-105 and the 28-200. And maybe the the 70-200 f/4.

A hesitation, I do not have very stable hands so I could be running up the shutter speed and ISO at the long end. But I guess Lightroom Denoise is always there.

I have another question. My Sigma Contemporary lenses fit very tight on the S1RII; to the point I worry about damaging the lens mount. I had the same issue with the S9, which is one of the reasons I sold that camera. How does the Sigma 20-200 mount on your S1RII? Is it overly stiff (or more like a Panasonic lens)?

There’s no Issue with mounting the 20-200 on either of my bodies (S5 and S1Rii).

Here are five consecutive shots at 1/13s at 200mm on the S1Rii. I was standing upright with no bracing to my body or arms or hands. All are pin-sharp - the images are 100% crops. I've shown the full scene too.

Yeah I saw that too. The 20-200 did very well. Some nasty vignetting at 20mm, and their copy fell off in resolution a bit at 200mm, but, as they said, the compromises are not surprising and well managed. I’ve not seen them test a travel zoom before; I’m happy to see it. The advances in lens design in this category are perhaps the most amazing we have seen industry-wide, even if they are not the sexy fast and ultra sharp lenses that often get the spotlight.

Having spent more time with the lens now, I can definitely say that the vignetting at the wide end is its worst fault. Even for someone who usually adds a vignette to most of my images I find it's a bit much! But it's OK, I can live with it. It's totally correctable in PP of course.

I'm not finding the optical performance at 200mm to be much worse than the rest of the range though. It seems pretty good (see the above images of the teapot!).

Yes, no doubt. 50 lp/mm (what Lensrtip reports at the center, at F8 & 200mm) is still above what they consider the “decency level” for a 43 MP sensor. So, no shame there. And it’s good to know your lens isn’t indecent!
