I've had an adapted SAL 70-300G SSW (version I) with the LAEA4 on my A7 for about two years now. I've been extremely happy with its IQ. It has a couple of drawbacks for the A7 use that I was interested in addressing; 1) no OSS, and 2) its minimum focus distance is a little longer than I like.

Adapter issues are also a factor; there's the chunkiness of the LAEA4, and its focusing system seems a bit unresponsive (although I suspect my LAEA4 is not functioning as well as it should be, which might be contributing to that problem). Since the A7 does not have the on-sensor update to PDAF which would enable it to use the LAEA3 properly with this lens, I don't have that option to go with, either, unfortunately, (and I'm not going to update the body until I see what the A7III has to offer next year when they announce it.)

So, when Sony announced the FE version of this lens, I thought it would solve all of the problems I have with the A-mount version. The FE version has gotten very good reviews, and people who've bought the lens seem to like it very much. I decided to order one last week.

After using the FE for a few days, I have a couple of thoughts about it. I have not given it as thorough a workout yet as I need to for a definitive conclusion overall, but I do have a few impressions about it so far vs the SAL version.

The good:

1) Color rendition is a bit nicer (IMO) than the SAL. It's a little cooler overall; with the A-mount version being a bit warmer (I prefer the cooler, personally). Greens are better on the FE.

2) AF is night and day better on the FE. Not sure how the AF of the SAL would be on the LAEA3 on newer bodies, but the FE AF is excellent. Fast, on target, easy.

3) Minimum focus distance is just close enough that you can use this for flower shots if you don't want to dig out the macro lens (it's not a macro, but you can get pretty close with it).

3) Sharpness is very good.

4) Very contrasty lens (this may or may not be a plus, see below).

5) Balances well on the body, even though it's not a small lens

6) It's nice having OSS in the lens on a long lens like this, and it does work well.

The bad:

1) Bokeh can be pretty busy in the right circumstances. Definitely prefer the SAL in this regard.

2) Even though its sharpness is admirable, the FE lens gives me the impression of a kind of digital crunchiness in its output. There is no lyrical quality to its shots. The SAL, while also sharp, just has something more pleasing about the output that I seem to prefer.

So, so far, there are thus only a couple of negatives about it. Unfortunately, they are negatives that mean something to me, even if they are apparently a little trivial.

This reminds me a lot of one of the highly recommended and well reviewed M43 lenses that I bought after it came out; the Oly 45mm f1.8. It was a modestly priced, but very sharp and very well reviewed lens, and everyone was raving about it. After I used mine for a while, I found that it left me very cold. The images were tack sharp, it focused fast, and it was a nice addition to the kit, but they all had sort of a clinical, soulless look to them, to me. After working with it off and on for a year, I ended up selling it, and going back to a legacy 50mm Yashica ML f1.7 for when I wanted something in that focal length (a lens that has just beautiful rendering). Unfortunately, I am getting that same feeling from the FE after working with its images for a few days....so I need to go out and try it on a variety of subjects to see how it does before I decide whether to keep it or sell it.

I think if I had a body with IBIS and could use the LAEA3, there would be no question at all that I would keep the SAL version. Unfortunately, I don't, and won't be updating the A7 body for at least a year, so that's kind of a conundrum.....

Oh, one other thing. Since this is entirely subjective, feel free to tell me I must be a total nut (this IS the Internet, after all); especially since I have not posted photos demonstrating what I am seeing.

On the other hand, a few months ago there was a lengthy post about lenses over on M43, and the 45mm f1.8 came up, and amazingly enough, out of the woodwork came a whole bunch of people who had had the same impression/experience that I did with that lens.....and I hadn't even posted my thoughts about it first. So, my experiences tend to be shared by at least a subset of folks, as a rule.....

Remember YMMV........

Thanks for posting your thoughts. Any samples on how sharp it is at say around 200mm? I'm currently using a Leica 180mm APO which is an amazing lens but I think at this focal length and onward, I'd like to get AF and IBIS. I'd be willing to trade down on IQ if it wasn't too atrociously bad. Other two options I'm considering is the Sony 70-200mm f4 and the Canon 70-200mm f4 although the Canon is effectively out of the running after I read through the philipreeve review on it.

I don't have any complaints about sharpness with this lens so far. I have not specifically tried it at 200mm, as I find myself usually using it either all the way out at 300 or backed way down to minimum, as a rule. I'll be trying it out more later this week, I think, and will post images after I have more of a chance to get some representative ones.

Its IQ is not atrociously bad!!! It's a very good lens, it's just a bit clinical for my taste, so far.

I'm overall happy with my FE 70-300, but I have no experience with the A mount version for comparison.

It seems to be equally sharp throughout the zoom range, but that is just from my not recalling anything noticeable.

I like the rendering from the lens, especially the OOF rendering. I guess we all have personal preferences.

My biggest disappointment with the lens is manual focus in low light. I have used it for night cityscapes and it's a bother to get critical sharpness using focus by wire. It also extends considerably when zoomed out to 300mm and the minimum focus distance is a bit long for me.

Here's an album of shots using the FE 70-300mm.

Thank you so much for sharing your candid thoughts re the FE70-300mm and found them to be very interesting/informative. Since the FE 70-300mm came out it has crossed my mind (a few times) as to whether or not to move to the new and improved version. In saying that, I have been very happy with the SAL 70-300GV1 (purchased last year on eBay) used with the LAE A3 adapter on the A7Rll. One of my primary reasons for switching would be to eliminate the need for an adapter, so the justification has eluded me for I still need to use the adapter for couple of other lenses on the A7Rll. Since already having a M4/3 setup, which seems to be the 'go to' for wildlife because it light and long; hence the need to upgrade to the FE version is questionable at this time. Of course, that is always subject to change!! :-D

Cheers
 
Same experience here. Found it extremely sharp but disappointed by both the lack of contrast and the distracting busy/crunchy bokeh.

Bought the A7RII for its small size but the Sony lenses outside of the "pro" 2.8 zooms and 1.4 primes have way too many compromises (55mm 1.8 being the exception). And the "pro" lenses are awkward on the smaller body.
 
I’m late to the party but have been waiting to get my replacement FE 70-300G to adequately compare it to the SAL 70-300G. All my tests so far are artificial, of course, but they are telling. The FE is impressive and significantly better.

This test shot shows the entire test chart and details of the the central area. The 30”x48” chart has been slightly cropped top and bottom for clarity. The entire test surface is approximately 34 feet away.

There is a red outlined insert of the central USAF-1951 target at 100% from my replacement Sony FE 70-300G wide open @5.6 at 300mm . Added to the right of the actual chart area and outlined in green is the same '51 target section but taken with the Sony SAL 70-300G/LA-EA3 using the same a7RII, lighting and settings

Out of the 42MP image those horizontal and vertical ‘1-3’ triplets exist in a roughly '9 pixels on a side' square box . On the actual chart the individual lines are approximately 0.25mm thick. False color is appearing on these triplets and smaller, presumably due to Moiré. At this point the 43MP FF sensor is the limiting factor.

My test images were processed from RAW using default settings in ACR except for color balance set to 2750K and lens profiles checked. There was no exposure value compensation but in Photoshop levels were tweaked to re-set the black point a bit.

It is also noteworthy that the auto-focus SAL 70-300G test shots were marginally focus variable whereas the FE70-300G shots were all dead on...all 200+ of them

Like the OP , I'm very impressed by focusing speed, close focus ability and especially center sharpness and stabilization.
