It might be if the quality is there at 400mm & the price is attractive.

Yea, but at 300mm, the 100-400 will be f5.6 or thereabouts.

To slow and already diffraction limited at the long end.

Paul was comparing max aperture at 300mm.
At 300mm the Oly F4/300 will be F4! (no TC required)

Re: Oly 300 f4 spoiler?

The voting suggests that 19% will buy it. On the whole I would prefer a zoom to a prime but I will take some persuading to part with my 50-200+EC14 in favour of either newer lens.

Re: Oly 300 f4 spoiler?

They're going to be very different lenses, I think.

For a start you've got the flexibility of the zoom, especially for mobile wildlife, and it's greater innate reach, but to set against that the prime is faster and in principle lighter and smaller and hopefully cheaper (!). It's also usable with the t/c, but again at a fixed focal length.

Surely the question to ask first before spending what will be a large amount of cash for any of us is "what can't I do now that one of these will allow me to do, or significantly improve my ability"? When you've answered that (with some genuine and significant benefit to you yourself) you should be well on the way to answering which one to get.

For me to get either will require the E-M1 replacement to have significantly better CA capabilities plus, ideally, a bit better high ISO performance. In that case I would like to develop my skills more in to a variety of sports, wildlife and bird photography. I'm content to dabble in these now and the E-M1/40-150/1.4 combo is easily good enough for that.

If this comes to pass I'll then probably just have one difficult decision: whether to go for the speed of the Oly (best for game drives, indoor sports and early morning birding) or the flexibility of the Panny.

Re: Oly 300 f4 spoiler?

Doesn't sound as interesting as the 300 f/4 to me but each one to their own

It might mean the 300 f4 is very close.

Re: Oly 300 f4 spoiler?

Mmm! A poser. Hopefully real world tests, when they eventually reach us, will suggest which is best.

Re: Oly 300 f4 spoiler?

This is the link to more info and image of the actual lens:http://donsphoto.com/blog/2015/07/an...uiv-zoom-lens/
I have used the Leica DG lenses and have found them to be both sharp and with a very pleasing OOF transition. I am interested!

Re: Oly 300 f4 spoiler?

I am sure the Panasonic Leica lens will be excellent but a) it's a zoom (so the optical design is more of a compromise) and b) as previously mentioned, it will be slower (less bright) at 300mm. It will probably be larger and heavier, too. There is plenty of room for both of these lenses in the Micro Four Thirds armoury

Re: Oly 300 f4 spoiler?

Thank you Ian. Yes a zoom is very often a compromise, although I have used very high quality (and expensive!) Leica R zooms with a small zoom range that have been described as the equal of each of the equivalent focal length Leica prime lenses that were also available at the time.

The big advantage that a zoom lens provides over a prime lens when photographing wildlife, is the speed which one can re-zoom and focus when the darned critter suddenly decides to position itself much closer!

As always, it's horses for courses!
