Ok ok, so where are the FASTER ZOOMS?

[originalhype]

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.

Panasonic have announced an f/1.7 10-25mm zoom, but expect it to be very, VERY expensive. Designing fast zooms is no easy task.

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.

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.

My early guess? $2500.

No one makes a 20-50mm/f3.4 equivalent lens right now. f/4 lenses in that general focal range sell for $900-1300, whereas f2.8 version sell for $1500-2500. None have as versatile a focal range, going from ultrawide all the way to normal.

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.

If you pull focus for video then you can adapt existing fast zooms, especially the four-thirds 14-35/2.0 and 35-100/2.0 SHGs, which adapt directly. I presume there are similarly fast zooms for other formats that can be adapted.

For AF video or stills you'd want an E-M1 to have PDAF focus for the SHGs, which work great. They're slow as heck with CDAF.

There may eventually m4/3 be constant-aperture </= 2.0 zooms but as noted above, surely over $2k. May as well save up for the Pro 1.2s, which are all great.

Cheers,

Rick

Serious question. I simply want to know your reasons for wanting faster zooms.

If you are willing to give up 1/2 a stop you can get a brand new 25mm F 1.7 for $147 (Amazon and likely matched by camera stores).

That is disappointing Mark a 5mm F/1.4 for $300 sounded interesting

shooting in low light so i don't have to set the ISO high. Can be the one zoom lens to rule all zoom lens. . Background blur? Bokeh. Finally, the technology got so much better than f2.8 should not be the norm anymore.

You could also argue as ISO has slowly gotten better over time that there is less need for the F/2.8 zooms

 

[JaKing]

Lens speed (optical) is a function of the physical attributes of the lens (front element size and focal length, in crude terms). Technology has nothing to do with lens speed ...

Faster lenses have much bigger front elements, therefore physically bigger, heavier and exponentially more expensive.

I got you OP...

<sarcasm>

Zeiss 21-100mm T2.9-3.9 LWZ.3 Lightweight Zoom Lens with Micro Four Thirds Fit, your for the measly sum of £8,484!

Details HERE .

Or if you are feeling flush you could opt for the Zeiss 15-30mm T2.9 CZ.2 Cine Zoom Lens in Micro Four Thirds, yours for only £18,686!

"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!

Lens speed (optical) is a function of the physical attributes of the lens (front element size and focal length, in crude terms).

My 20mm lens has a 24mm front element. That makes it an f/0.833 lens. What a bargain, 'cause they sold it to me as an f/1.7.

Technology has nothing to do with lens speed ...

I suppose that's true, if you don't mind about things like aberrations.

Faster lenses have much bigger front elements, therefore physically bigger, heavier and exponentially more expensive.

Could it not also have something to do with all the other elements in there too? Olympus put 17 of them in their 25/1.2. Nobody told them they only had to put in a big front element.

 

[EarthQuake]

If you don't mind big, heavy, and expensive (which an F2 or faster zoom will necessarily be) you have options.

The Olympus 43 14-35/2 and 35-100/2 work well when adapted to PDAF bodies like the EM1. These are expensive at retail but sell for about 1/2 the price used on eBay.

The Sigma 1.8 zooms in Canon EF mount can be adapted with Metabones or Viltrox adapters and give you AF (though not on the same level as native lenses). If you use a speedbooster this will give F1.3.

Shameless plug - the 14-35 f2 is one of the best zooms ever made... And I have one on eBay

The Canon EF route has me intrigued, but I worry that the price of quality Canon glass outweighs the worth with the newer mft 1.2 lenses being released.
