About f11 equivalent in large format terms.


True, but the point of this lens is being small, and it is much smaller than the equivalent 200-600 f/11 for 4x5" would be.

The Panasonic 35-100/2.8 is equivalent to 200-600mm f/16 in large format (4x5") terms.


thats VERY interesting.
How much is it in 6x45, 6x6 and 6x7? I'm sure everyone here is DYING to know.

This really defeats the purpose having a "lightweight, pocketable, and small full-frame" camera doesn't it?

Or just don't use this lens when you want lightweight, pocketable and small full-frame.

I know you're just making a joke, but "slow" and "fast" is absolutely dependent on sensor size. The equivalent 4/3 lens to this would be the Olympus 35-100 f2, which is larger, twice the weight, and $2500.

For those that like to calculate their depth of field and use it artistically, knowing the speed equivalences between different formats is important.

I pre-ordered it. If it arrives before my trip to Namibia in April and does suck optically or have shutter vibration issues, I'll keep it. Otherwise it goes back or the pre-order gets cancelled.


Is there a not missing in this statement Aravind?!? Lol

I know you were being funny

Seriously, though, the equivalents for APS-C (50-150 f/2.8) and u43 (35-100 f/2.0) are increasingly large and heavy.

This makes no sense to me at all....sorry....large lens on mirrorless....stupid, IMHO


So what are the advantages of a large and heavy DSLR with a large lens? Even more weight to haul and mirror slap?
As long as the AF works, I don't see any disadvantage with mirrorless on a long lens. "balance" is not a factor because large lens systems are supported / held by the lens anyway.

I really hope that a 70-400 OSS is in the roadmap for FE.

I'm sorry but it weights only 840 grams. I don't see the reason to panic.

MFT is where it's at for size/weight/IQ balance for longer focal lengths. I can't see any other format competing with the 35-100mm.

Yup, that old law of physics just keeps getting in the way. m43 owners keep thinking owning a small sensor equals much smaller lenses. It's simply not true. You must still sacrifice something to get smaller optics. I was recently checking out the images from the 35-100 on flickr (I keep thinking m43 might be fine for zooms) shot wide open. I've owned both the 70-200/2.8 and f/4 versions for Canon and Nikon and am familiar with the looks of those lenses. The Panasonic just doesn't have the same look. I'm sure it's a fine tele zoom if all you want is to bring subjects in closer, but if you're used to a certain look on FF and want that look in a smaller package, it's nearly impossible to do. It is one reason I mostly shoot primes now. I sacrifice zoom for a smaller package and zoom with my feet now.

That's a joke right?

m43 has the terrific Panasonic 35-100mm f2.8 IS.

That is valid only for a certain degree of IQ and speed equivalent.

Every format has its compromises but a lens that is simply too heavy to take and use throws equivalence out the window.

Just a curious observation: It seems that FF shooters have a higher tolerance for smaller system users jumping in and mentioning equivalence in their lens discussion, than those smaller system users have for FF shooters to mentioning equivalence in their lens discussions.

The Olympus 40-150mm (80-300mm equivalent) f/2.8 lens will be released later this year.

I agree. I'm praying Sony will release such a lens in the near future.

I agree.

There are so many stupid comments in this thread. It's just ridiculous to expect the 70-200mm f/4 lens to be small if you want it to perform well. Not to mention that this lens is for a FF camera.
