appreciate the info! if it's sells for $1000 and it will sell.

That would be a great lens for video and wide open and vacation.

In your dreams . I would expect $2500-3000, but we'll have to wait and see.

Maybe keep going, lol

"exacting standards" of Leica. "Built for video", so par focal. "first zoom with an aperture ring for the Lumix G system" and "first to offer clickless control of the ring"

Take whatever you think the high number is, and go up!

PANASONIC did not even need leica to develop that lens. Just by adding leica on the name suddenly the price goes 2x. It should have just been a pan lens.

Hell pan and oly don't even make pancake lense anymore. sad.

I will not accept that any camera brands use ISO or software aided to make things brighter. I prefer lens that are bright for night shots.

Are you opposed to using a speedbooster with the Sigma 18-35 F1.8 or 50-100 f1.8 canon mount? That gives the equivalent of F1.2 and 13-26mm compared to other micro 4/3 lenses. Autofocus works decent for pictures with the metabones or viltrox speedbooster but you cant count on it for video at all.

Not oppose at all. I welcome it but Just do not effin understand why oly or pan did not even try to produce them. it took pan 8 years to even announce one.

Well, I have retired my panasonic GX1 and will be selling it as i recently bought the olympus em5 ii. I got it for a good deal at $475 during the recent sales.

So back to the subject, since I will also be using the em5 ii for photo and video due to its 1080p video and mic capabilities. I am looking at the zoom lenses only to find out we are still at f2.8.

I had my panasonic gx1 since 2012 and fast forward still no faster zoom such as f2 or f1.8 CONSTANT.

If sigma can do it for crop sensors then surely the size of an f.18 zoom lens for this system should be smaller.

The prime lens for f1.2 from olympus are expensive and no plans from what I am seeing from roadmaps.

sad.

BTW my next lenses will be a pana leica 5mm f1.4 since i am now seeing it for $300.

Just been browsing and in UK I could pick up a used 35-100 f2 for £500 with warranty.

You would need an adapter and it is a big heavy lens.

No free lunch though!

Great question. My only guess is that they focus more on sports and wildlife which just dont care too much about fast lenses. Getting sharp and long lenses are more important I guess? Im a big fan of shallow DOF and low light so all my lenses are fast canon primes and the sigma with the speedbooster adapter on my Panasonic G9. There are a few Voigtlander all manual lenses that get down below F/1 for M4/3 but its all manual. I dont mind manual lenses and most of mine are. Just depends on whats most important for you.

That is a superb price for what { size not withstanding

Any portraitist should run, not walk to grab one at that price. No system zoom can replicate it, either the shallow DoF or the dreamy bokeh. And yes, it's big as a big thing.

A Canon 16-35/2.8 II with a 0.64x Speed Booster XL is very close to these specs at 10.2-22.5mm f/1.8, and costs ~$2k. The newer III version of the 16-35 is about $600 more. These are probably useful benchmarks to judge the price and performance of the new Panasonic lens.

There are very few zooms faster than f/2.8 for any mount - Canon has just announced a 28-70mm f/2 for its new EOS R mount , Sigma has the 18-35mm f/1.8, Olympus had a couple of f/2 zooms for its 4/3 DSLRs, but I don't think that Nikon, Pentax Sony or Fujifilm have any. There have probably been a few older very fast zooms.

As Chris has said, fast zooms are very difficult to design and very expensive. It is much easier to design fast primes instead.

High performance F/2 zooms are pretty common for M43. Just attach a 0.71x Speed Booster to any mount-compatible fullframe SLR f/2.8 zoom. These become f/1.8 zooms with a 0.64x Speed Booster XL. The f/1.8 Sigma zooms become f/1.2 with a 0.71x.

What's interesting there is, if you choose APS-C lenses, how much smaller they end up than the old Olympus f/2.0 lenses.

Sigma is the only company that makes 1.8 zooms and they are on 2x zoom every other company makes 2.8. At least all the major companies there may be some obscure company that makes a faster.

There are plenty of companies making f/1.8 zooms. For instance, this camera has a 20x f/1.8 lens

Most of the size and expense of a zoom is building the variable magnification section at the front of the lens, to cover the design ranges of angle of view and aperture. What is the actual focal length and f-number really just depends on the optical power at the back of the lens. The lens above has a focal length of 3.67-73.4mm, which means an aperture range of 2.03-40.7mm, which means it's a feasible lens. You can't really compare the challenge of a f/1.8 zoom on mFT with that of an f/1.8 on APS-C. An f/1.8 mFT zoom would be much the same in optical terms as an f/2.3 on APS-C or an f/3.6 on FF, as is evidenced by Brian's point about using a focal reducer to produce one.

stick with primes for anything faster than f2.8. I doubt O or P will develop any zooms faster than f2.8 and all of the Sigma lenses for m43 have been APSC lenses that they slapped a m43 mount on so they aren't going to do it.

I don't really see this as a problem though. If wanting to do something with a zoom lens that f2.8 on m43 will not accomplish you're better off just going with a larger format. There are plenty of f4 FF zooms that do the same thing a f2 zoom on m43 will do. I have the Canon 16-34 4L IS, 24-70 4L IS and 70-200 4L IS and all do a superb job and cost less than the f2.8 m43 zooms. No real reason to worry about m43 not having this when it is easily attainable elsewhere and at very affordable prices. I shutter to think what O or P would charge for a f2 zoom if it existed.

What of the 10-25/1.7 ?
