TRYING TO DECIDE BETWEEN TWO LENSES...

[TOPSHELFJR.]

So I want to add a 70-200 2.8 to my kit... And I'm not sure if I should reach for the pricier Lumix S PRO 2.8 or the Sigma 70-200 2.8 ?! Anybody have any thoughts on these two ? Image quality difference ? Worth it in price ? Weight ? Let me know..

A couple of months ago I was in the same situation. I decided for the Sigma 70-200/2.8 sports DG DN and never regretted it.

The deciding factor for me was size, weight, price and the fact that a lens with sports in the name might be better in the AF for sports photography, which is the main (or only) use case for me for this lens.

The Sigma has a very good image quality even on the S1R2 and the AF dies not disappoint with erratic spirts (field hockey). When I am back from travelling, I will post some expamples.

I forgot that posted already some images with this combination:

Fun with Lumix S1Rii / S1II /S1IIe & sports photography

I start this thread for all members who do sports photography with the S1Rii / S1II /S1IIe. Feel free to add your images in this thread. Here are some images made with the Lumix S1Rii and the Sigma 70-200/2.8 DG DN OS Sports of yesterday in field hockey. I am really happy with this...

There are also more "practical" reasons to consider that can have a bigger impact in real life than only comparison of optical qualities.

A choice also can depend on other zoom lenses you are using already. (E.g. owning a Sigma or Panasonic 24-70 mm zoomlens ?)
As e.g. the rotation of the zoom ring from wide-angle to telephoto is the opposite direction for the Sigma and Panasonic brand.
So changing from one zoom-lens brand to the other - and using Sigma as well Panasonic.
You definitely will make mistakes zooming in and out, which direction to turn the zoomring.

Panasonic having a bayonet type of hood.
Sigma you have to slide the lens hood to the lens, and clamp it with a screw on the side.

Taking off the tripod feet:


But the Panasonic lens is much more heavy, than the Sigma lens.

I bought a Panasonic 70-200 f4 last year and I’m very happy with it. But I don’t need f2.8 so I preferred the smaller and lighter f4. However I had a good look at the Panasonic f2.8 and also the Sigma. I really liked the Sigma and was very tempted to buy it, even though it is quite a bit heavier than the Panasonic f4. The Panasonic f2.8 performs very well, but it’s notably bigger and heavier than the Sigma for no apparent benefit.
