Really Needed - very fast widish zoom

How about a 15-30 f1.4 pro ?

Until today I thought no more lenses were needed in the m43 lineup, but today I found I needed one that isn't yet available

I was at a village show photographing vehicles in the arena and alternating shots were at 17mm and 32mm, I hadn't anticipated this and so only had the Panasonic 14-140 with me which meant f3.5 - f4.

The big problem was even the far end of the arena and crowd were also in sharp focus

An f2.8 wouldn't be good enough as regards blurring the background, and using 2 cameras with fast f1.4 primes wouldn't work either as you couldn't swop fast enough.

I realise that a 15-30 (or even better 15-35) constant f1.4 would be pricey and heavy but I would snap one up immediately if under £1200.

And before anyone starts - I don't want to buy a FF as a second system!

Are there any others here who would enjoy a very fast widish zoom that covered a useful focal range?

Keep dreaming...   I don't see that happen below £2K.

Not me, personally. A 12-60 f/2.8 would be nice but I fear the price.

You must have missed the memo lol.

But I am in the minority that would be interested... within certain price and size limits!

But bare in mind that even a 17mm f1.2 Pro barely separates the background in a shot that would be framing a whole car.

A used Sigma 18-35 f1.8 in Canon EF mount and Viltrox speedbooster would be a f1.3 ish 13-25mm and both would likely cost a fraction of what a native 1.4 would likely cost.

Thus i assume your photography obviously doesn't require one

Yawn .

I haven't tried that lens (basically because I don't have access to one) but I have tried a sigma 10-20 which worked great on an aps-c DSLR, but its image quality when used on m43 is appalling. I am sure a speed booster may help, but it's an expensive risk. I would rather Olympus or Panasonic make the real deal.

You think l haven't tried that?

... It may work well with static subjects, but I don't do a lot of that 'sort of thing'!

Nope. I shoot events with three bodies, generally with 12, 20, and 45mm primes mounted. I can switch cameras in a few seconds.

Sigma DC 18-35mm f1.8 in EF mount

This lens works fine on M4/3 bodies with Metabones adapters and can be focal reduced:

13/25mm f1.2? Or plain old 18/35mm f1.8?

DC lenses are aps-c image circle so focal reduction puts their image circle full size on M4/3 bodies.  I have used this lens/adapter combination for some time on M4/3 bodies without any obvious problem.  The DC 50-100 f1.8 also works fine but struggles a little more with auto focus - but not enough to cause me any displeasure.

If you want a zoom lens with 1.4 DOF, get a full frame camera and a 2.8 lens. Problem solved. All other options are going to have some major drawbacks.

The Panasonic 12-35/2.8 is close to the cost that you would be happy with for a 15-30/1.4... So no, there is no chance that this would ever happen. Maybe for $4000. It would probably weight about 2.5-3 pounds too.

You could get an older full frame DSLR body with an inexpensive (Sigma, Tamron?) 28-70/2.8 for much less than this theoretical lens would cost, plus that combo would probably weigh less as well.

As others have mentioned, if you want to stay in the M43 system you could go with a speed booster and something like the Sigma 18-35/1.8. This would give you 13-25/1.3. Something a bit lighter and less expensive would be a ~16-50/2.8 from Canon / Sigma / Tamron, which would give you ~12-35/2. AF and general reliablity will be a concern with any of these though.

There's the Olympus 14-35/2 of course, with an appropriate adapter and on a body with PDAF like the EM1 that should work pretty well. It's giant and expensive and only F2 though, so a FF body with 2.8 will give you narrower DOF, at similar cost and size/weight.

Since you have the right camera for it, get the ZD14-35 f/2 and of course the MMF-3.  It works very well on my older EM-1 so it should be even better on the newer model. They are selling used for much less than their original price now.  It is the best available for m43.

And if the OP wants longer, he can use the same focal reducer with the Sigma 50-100 / 1.8A. Both of the lenses are stellar optics, and, more to the point, can be had right now for far less than what the lens the OP is asking for would end up selling for if and when it's ever made.

Thank you

Thank you all for your input - much of which was really valuable.

Re swapping between two cameras, it always makes me smile when people suggest that. Today I was photographing a motorcycle hill climb, and I am sure that with a little more practice I'll be able to get the swap time below 1/10sec going from camera to camera including re-finding the subject in the viewfinder and reframe and refocusing

Re: Really Needed - very fast widish zoom

I think that this is one of those specific instances where you need to change system for the look you are after. Maybe you could rent something just for the day?

I really can't see either Olympus or Panasonic wanting to create such a fast zoom with the size and cost penalties that will come with it. It would probably be a poor seller and a poor return on the investment of designing and making it.

Have you tried shooting it with say a 300mm Olympus pro but from further away? I have never used one, so I don't know what effect f4 is on that lens. Of course you would need to be quite a lot further away!

Alternatively, you may consider using software to blur the background in PP.
