There's an excellent review of the 35-100mm lens on Bill Castleman's site. Looks like it's not all that good for landscape/architecture due to the poor edge/corner resolution. Even the 14-45mm Panasonic trumps it at 45mm for edge/corner performance for overlapping apertures and it gets worse as you zoom to longer focal lengths. . . . The review confirms to me, at least, that I'm better off just using the 75mm f1.8 and cropping, if necessary, even for travel. It seems like it's designed as primarily a portrait/even lens.

I returned mine, def was not worth the 1,500

I wouldn't even use it for a portrait lens

Wow, those corner MTFs look horrible. I wonder if it's really indicative of the design or just a bad copy.

That's not been my experience at all. I've been extremely pleased with my 35-100. Quite sharp at f/2.8 and very very sharp at f/4. The corners aren't as sharp as the 75/1.8, but frankly there are VERY few lenses that are.

The 'wouldn't even use it as a portrait lens' comment seems extremely off to me. Is the 75/1.8 better? Yeah...but I think the 75/1.8 is one of the best lenses of all time, frankly...for any system. If I could only keep one, though, I'd keep the 35-100.

I also think you're looking at MTF vs one of the sharpest primes in existence and making big jumps in logic. At the end, he concludes by saying "Overall, this light weight, compact, high performance zoom is well worth the cost of purchase if you shoot candid event photos. I'm not sure I will be needing my Canon EOS system 70-200mm f/2.8L lens since this Panasonic 35-100mm lens will provide most of the photographic performance of the 70-200 at a fraction of the weight and size."

These are all with the 35-100:

Another thing to consider is that Castleman's MTF charts sometimes are very much wrong. I recall when he compared micro 4/3 25mm lenses and did the same huge error as Lenstip and concluded the Voigtländer is the sharpest ever, especially so at borders and corners. Lol, yes it is but only when shooting at very short distances (for example indoors framing a resolution chart).

I haven't tried the long zoom and have no idea about how it performs - but if I had been interested in such a lens I certainly would have tried it myself rather than decide anything based on Castleman's or Lenstip's or xxx's charts.

Reviving this thread a bit.

I've tried one copy of the 35-100/2.8 on my GH-2 and was not impressed - especially at the 100mm end. OK sharpness in the center, but poor borders/corners that really don't sharpen up when stopped down. I shoot a lot of things, one of them being landscapes while out in the mountains.

Is this still the general consensus or is this sample variation at play?

Alternatives are getting the 75/1.8 Oly (which I've tested and was hugely impressed) or waiting for the rumored 40-150/2.8 Oly that is supposed to come out next year (at unknown price, but I'm sure will be just as expensive as the 35-100 Pany).

Thanks for any further opinions over what's already been stated above.
