Hi Roger,

I found that my copy is very sharp at 200mm. Even wide open, it performs better at 200MM than it does at 70mm. Clearly my testing and judgement are not nearly as thorough and professional as yours, but I am curious to see if you notice the same thing when you get additional copies of the lens.

Cheers,
Dimitri Kavalieros

I got to shoot with one for a week. I found it awesome up to 150mm, but rather soft longer than that. I suspect my copy was a bit decentered at the long end so I'm reserving judgement until I get to see more copies.

Well, you can always get a 55-210 NEX lens then shoot a 10mpx size image in RAW based on coverage and shoot at ISO 6400 to gain back that loss of apeture ...

It's all what you are willing to sacrifice. I don't think that even Leica with the M-series FF cameras has a focal range lens that has AF and image stabilzation like this.

The comments that follow, state sensor size is really the biggest reason. Its a zoom-lens too, so the argument back about large format cameras (4x5, 8x10, etc) have smaller lenses that are also fast relative non-zoom capabilities of such a range - but they are also fixed w/ digital lens features.

Isn't it pretty obvious that once we're in the Tele range, we can forget about pocketability for good? Yet some people still think they can have their cake and eat it too. Stay below, like, 90mm (Voigtländer 90/3.5) and the setup might stay compact...

actually going with collapsible designs could allow for considerable space savings on telephotos with mirrorless FF cameras. you could make a nice 300mm that collapses down to the length that 90/3.5 + adapter (obviously it would be much fatter). build tolerances would have to be higher i imagine to maintain good centering though on something with a telescoping barrel.

I'm wary of collapsing designs until we have fully electronic shutters.

why? what problems have those caused with the panasonic, olympus, and sony designs?

also, most telephoto zooms are collapsing designs of a sort.

On the Olympus and Panasonic designs at least, collapsing zooms lead to great shutter shock effects. For example, the Panasonic 12-32mm, I tried two copies, are particularly prone to shutter shock at focal lengths where my primes on the same bodies and shutter speeds, rarely if not ever show shock.

The Olympus 14-42mm even in R II form also is more prone to SS than say the Panasonic 14mm.

That, and we're speaking of a semi-fast, stabilized premium design after all. F/4.5-5.6 ones can be smaller, of course, even for FF, but the likes of old Canon 55-200 or 80-200 plastic fantastics don't seem too good optically.

I just purchased a refurb FE 70-200..... one shot about 30 minutes after delivery



and a few more from the local "Native Rhythms Festival"







so far, so good except at one point it wouldn't focus properly until I turned off the camera & re-mounted the lens.

Realistically, its only going to get better. Take what exists for the a6000 as a baseline. Figure it will be a bit better or a bit worse. If you can live with either option, its a good choice for you.

Is it reasonable to assume that if the A9 (etc.) has focusing capabilities similar to modern DSLRs, that both the compact f/4 lens as well as the FF f/2.8 lens would focus with similar speed?

Of course. The f/2.8 was made for high speed focusing. Its design was actually by Minolta and replaced their 80-200 hs g, which may be faster, but with exponentially more noise. The f/4,for all intents and purposes, is a shrunk down version of the f/2.8. But if you can, find reviews or even rent one with the a6000. Its an excellent combo. Moreover,while af-c is a bit behind with Sony, the face detect af-c is ahead. For sports, as long as a face can be tracked, it does a great job. Could be an issue with things like soccer. However, Sony is making big strides. The a-mount a77ii does a great job. It will only get better as the techs converge.

Which is exactly why I'm not on the FF bandwagon for mirrorless. I went mirrorless because the lenses for my DSLR were huge. I have no desire to go back to that. The lens looks good, though and the price is fine....more competitive than I'd have expected given the prices for the primes.


I'm actually enthusiastic about trying this on the a6000, the fact that it covers FF is just icing on the cake.

A user on dpreview has received the lens and started a thread claiming the lens exhibits OSS shutter shock on the A7r. He says he doesn't see the issue with the A6000.


I suspect I'm getting shutter shock or just really poor OIS performance with this lens on both the A7 and the A6000 unfortunately. I get inconsistent sharpness below 1/160 with both. It is also softer than I find acceptable at F4 for a lens in this price bracket.
