Google has scanned old issues of Popular Photography, so it is pretty easy to find historical street prices of lenses. The 100-300 APO price fell quite a bit.

I am sure there are probably better performing copies than the ones I have had. It seems increasingly likely that they are somewhat rare. It sounds like there are quite a few poorer 55-300's too. I don't think there is really an answer to the original question. There are probably some sharp copies of the later 75-300 D's or the similar Sigma and Tamron zooms. Our database ranking is probably a pretty decent general guide for lenses that have statistically significant user reviews.

Ahoy!

Question. Why buy into an E-Mount system and then use full size A-Mount lenses? Personally, it makes no sense to me, but each to their own.

As for the SAL 70-300 G SSM, if you're referring to the first generation of the model, then don't waste your money on it as the Tamron A005S is half the price and AT LEAST (if not better) the Series 1 SAL 70-300 G SSM. I can't comment on the Series 2 of the SAL 70-300 G SSM as I've never used it, but there are still superior make/models of tele-zoom and tele-prime lenses. I cannot stress highly enough the importance of quality over budget. Personally, I wouldn't bother with maybe 90% of tele-zoom and tele-prime lenses available, thus buying cheap with low IQ capability is pointless as you'll then need to sell it to recover the money in order to put it towards a superior quality optic.

I don't use E-Mount, but to me it's a compact lightweight system, but whether it's being supported by 3rd party manufacturers to cover UWA, WA, zoom, prime, tele-prime/tele-zoom from 100mm - 400mm that are both affordable, but also produce top quality images, I don't know, but therein lies my reasoning, but as the E-Mount is a relatively new system and shooters don't have the range of lenses and budgets that A-Mount shooters have, and in order to use A-Mount lenses, you also have to buy an adapter which may also be the case for the new hot-shoe mount, so another adapter required

The E-Mount reminds me of why motor manufacturers produce engines with a timing belt opposed to a timing chain. A chain requires no time/mileage replacement unlike a belt which has to be changed by time or mileage intervals (whichever comes first) and this translates into repeat business via the main dealer service bay, so a belt is nothing more than a cash-cow (a means to generate additional income). It doesn't cost any more to produce an engine with a timing chain hence why I've used the belt/chain analogy to the E-Mount, but no doubt I'm way off target, though I'm sure the OP has already done their due diligence checking all zoom and prime telephoto lenses via the Dyxum lens database. It's a wonderful place to check all types of lenses and other features and functions with image samples in order to make a shortlist.

Answer: The FE 70-300G is an E-mount lens. All Sony 'FE' lenses are full frame E-mount.

Ahoy!

I'm almost sure there's something else the Minolta (D) 8-pin lenses produce, but I agree about the distance encoder for flashgun use which measures both distance and light in order to meter both so the correct flash output will be calculated, so ADI metering rather than TTL metering, but the OP should double check the user manual about settings, but I would set the ISO to 100 and the WB to flash and also turn off any in-camera auto settings, modes, noise-reduction + *more (*which I can't remember right now), and change the image size to maximum and format to cRAW.

Whilst other Dyxumer's will no doubt have their say, I would be inclined to stop, listen and follow the advice given.

Just my tuppence worth.

I have tried that Tamron. It is in that comparison I linked to earlier. And I found it mostly worse than the 55-300. I am sure there a better and worse A-mount 70-300G's too. The one DXOMark tested scored better than any other xx-300mm zoom for sharpness. The Tamron 70-300USD's they tested faired less well. I am sure you had a different experience. I expect the A-mount 70-300G2 is a very good lens, but the FE 70-300G seems like a better investment to me.

FWIW: from my brief testing yesterday, the A6300 seems to have better AF with motorized A-mount lenses than the current A-mount bodies do with the same lenses. The A6500 has better stabilization.

And from the other thread: D lenses get x- and y-axis stabilization.

Also the focus ring doesn't turn by AF, and you get DMF with the last Minolta SLRs.

I can't agree with that. It is clearly a variant of the 100-300 with some apochromatic compensation added, and that is very effective. The CA/PF is much reduced comapred with the 100-300 and any of the older xx-300mm lenses I've tried. The Min 75-300mm was quite bad wide open IME. I did a lot of comparative tests of CA on my local cell-phone tower until I moved jobs, and of course the latest dt lenses like the 55-300mm benefit from in-camera corrections. I know there's a lot of nostalgia about the older lenses, but IME they just wont stand pixel-peeping the way you can with Sony dt lenses unless
(a) they are APO enough to kill the CA in the corners
(b) they are sharper than average
(c) you stay away from full aperture.

Some of them suffer from veiling in sky shots too which the later lenses are usually immune from. The 55-300mm is a very good lens IME, it's just so damn big.
A900, A58, 5d, Dynax 4, 5, 60, 500si/600si/700si/800si, various Sony & Minolta lenses, several Tamrons, lots of MF primes and *far* too many old film cameras . . .
