300mm f2.8 which one?

Yeah, but those are manual focus lenses that are all-metal and with no electronic linkages.

The 300mm f/2.8 has SSM which means that it has a critical point of failure with the SSM motor/electronics as there is no fallback to body driven focusing.
That's a good point and I should have taken that into account. I wish I still had that Soligor because it was built like a tank, very low CA and was very sharp. I could have used it with an adapter.

Not long ago in this forum, there was a report of damaged Minolta 300 2.8 with faulty SSM, repair shop could not fix/replace SSM (not the same as Sony). So the owner is left in the dark.
WHAT ???? Is there any official report/message/mail from Sony for that ?

first time I read this ! Do you have the link of the thread ?

(If ultrasonic dead (HSM, SSM, USM whatever) manual focus is not possible either....
 
Minolta 300mm f/2.8 G SSM is great and Sony simply rabadged this lens.

Minolta 300mm f/2.8 G HS is different, older and SSM version is a little better.

IF he can afford SSM - it's best choice (and always can repair in sony service, but for pay).

Know nothnig about Sigma here.

I haven't heard that the Minolta SSM version is better than the HS screw drive - I thought they were the same - but, as someone pointed out earlier in the thread, if the Minolta 300 SSM fails you're in trouble. There's something to be said for lenses being simple passive items, especially as they last a long time and are very expensive.
 
the SSM IS better than the HS :

better AF, better lens hood, better ergonomic (focus limiter) AND especially BALANCE (all the weight on the front for the HS).

Better IQ at f2,8 (the difference is lower after f4).

Better quality with TCs, that you can find new in Sony.
 
the SSM IS better than the HS :

better AF
I guess you mean the speed of AF because the camera does the focusing. There was a thread on dyxum a couple of years ago where they compared a 300mm SSM with a 300mm HS and they found that the screw drive was marginally quicker when using an A700. Can't remember what they said about IQ but I don't remember there being any difference. I certainly can't tell any difference in IQ on my 300mm f2.8 HS between f2.8 and f4 - if there is any difference it's very small.
 
This Sigma was reviewed by photozone and seems to be sharper than the Sigma prime 300mm f2.8, is much cheaper than the OEM 300mm f2.8 primes and also has 4 stop vibration control, great Sigma warranty, etc.

I would go for that one, but I don't depend on photography for a living so you can take my opinion for what it is worth.
 
The only problem is there is no Sony mount for this 120-300/2.8, only Canikon & Sigma versions.

AF can be much more efficient because of the Focus limiter settings on the ssm

there are some IQ differences between f2,8 and f4, even on film camera : I have read some tests (paper magazine as well as web testers, see artphoto as example) which are consistant with my personnal 300/2,8. CA are bigger and sharpness is lower at f2,8...

you'd better keep your copy preciously ! ;)

to see a very good comparison of the following lenses:
Sony 300 f2.8 G SSM
Minolta 300 f2.8 G HS
Sony 70-400 G SSM
Minolta 200 f2.8 G with 1.4x TC
I think they had a bad specimen of the Minolta 300 - it's obviously an old lens and I reckon the one that he tested needed a bit of work. I've also got a Sony 70-200 f2.8 G and the Sony 1.4X TC and there's no way that it's better than my Minolta 300mm f2.8. The Sony 70-200/1.4TC is a very good combo but it doesn't deliver sharp images at full aperture like the 300mm f2.8 does.

I've often wondered how much difference there is between individual samples - I suspect that there may be significant variation.
 
Wow!

A lot of answers! Thank you all!

To answer to your question:

My friend's main interest is flowers and insects (especially butterflies) but he wants to photograph birds. He fallen in love with nature when he started birding and acquired his bird ringing permit about 20 years ago. His situation is a little bit special, in this region the fishing ponds are located in deep valleys so it is about an hour after sunrise when the light reaches the water surface. So every bit of extra light is highly appreciated.
 
Actually that thread inspired me to start this one...

The owner of that faulty lens has not replied for a month now...

If he could force Sony to repair that lens my friend's question is anwered but otherwise its pretty risky you'll end up with an expensive paperweight.

The Sony 70-200 f2.8 G was not one of the lenses tested. It was the prime 200mm f2.8 with the 1.4x TC. Big difference, as the prime 200mm f2.8 is one of the very best primes Minolta ever made.

A fortnight ago I wanted to clarify the issue whether and when Sigma may produce an a-mount version of that lens, so I posted an inquiry to Sigma USA (see below). As they were unaware of any such plans I tried to contact Sigma HQ in Japan directly, alas, they do not give an e-mail address on their homepage, so I am still hoping, Sigma US will pass on my message to Japan - but it seems they cannot be bothered. The fact that it seems to be really hard for customers committed to the Sony-System to obtain some clear information has considerably reduced my interest in Sigma - products now.
Or would any of you know a direct way to access that info ?
(No, I do not feel like writing and posting a letter to Japan overseas........)

cheers
Stefan

my correspondence with Sigma USA:

"Dear Desiree,

thanks for your reply.
Would you be able to please pass on my request to the headquarters that
could give the reasons ?

There is a whole community of dedicated photographers waiting for an answer to this question.

Kind Regards

Thank you for contacting Sigma Corporation of America.
There is currently no production date planned for a Sony mount of the
lens.
We are not sure of the reasoning behind it as we are just a US
distributor.

Question: Dear Sigma team, nature/wildlife photographers with Sony A mount
DSLRS are missing an A-mount version of this lens: 120-300mm F2.8 EX DG OS
APO HSM Does Sigma plan to offer such a lens for Minolta/Sony users ? If
yes, when would this become available ? If not, what arguments would induce
Sigma not to offer that mount ? We Sony users have been hoping for that
lens quite a while, and with the advent of new Sony DSLRs like the alfa77 we
are likely to see the demand increase further. KInd regards

I made my decision; my Minolta 300 2.8 APO G is being delivered today from the B&H warehouse. Thousands cheaper than the Sony, but 9+ quality.
