Sigma 150-500mm F5-6,3 DG APO OS HSM the perfect low budget safari and wilde life lens?

During this review of the Sigma 150-500mm OS, I will try to find out if it fulfill my expectations and needs as a enthusiastic

I didn't find any review of this new lens from sigma when I first
heard about it anyhow due to an upcoming expedition style polar-
bear safari to Svalbard I just had to get a long lens to bring.

The Nikon 80-400mm VR , Sigma 80-400mm OS was at the time
the only alternatives available to me since optical stabilization
was a must have criteria.

The Nikon lens had a bad reputation for being slow due to non AF-S
design so I was heading towards the slightly faster focusing Sigma

Then the 150-500mm OS was announced and I just had to sit an
wait to se if it was about to be available before the Svalbard trip.

I got the lens one week before we left for Svalbard, and I must say
I couldn't have lived without it.

Back from Svalbard I decided to try to do a review of this New
Sigma lens that not only gave me some nice polar bear shots.

The 150-500mm OS HSM also suprised me of being quite a bit
cheaper than the old and discontinued 80-400 from the same

That was a short presentation of this
new exciting lens from Sigma I will
make a review of this lens in my own
way of reviewing things you might like
it or might not (I'm not a pro nor am I Ken Rockwell).

The proffesional way to review lenses
is way to complex for me :0) click

Few words will be written, but there
will be many photos in this review to
help you evaluate this lens by your

Review will start A.S.A.P , and will run
until I find it done. To start with I will
compare the Sigma 150-500mm OS to
the good old Sigma 80-400mm OS that
I have on loan from a friend.

The trusty old 80-400 has the EX marking and the corresponding golden stripe the 150-500mm OS does not.
Anyhow I can't spot any difference in built quality between them.

As a matter of fact this lens does not carry the EX designation because Sigma will now only use that for lenses with a fixed aperture. It's still seems built like an
EX lens would be, there's no difference in that respect.

The 150-500mm is new cheaper faster focusing and available.
The 80-400mmis more expensive and according [discontinued]

Both lenses ships with a removable tripod collar of quite god quality
a lens hood and a big high quality synthetic carrying case that are big and bulky
[go here to se how to make a new one for backpacking].

The 150-500 came with a new improved lens cap that looks similar
to a Nikon lens cap it almost looks cloned :0)

Sigma lenscap for Nikon 150-500mm OS

Both lenses are equiped with Zoom lock (I wish my Nikon 18-200 Vr had the same)

On the next page I will start to compare optical quality.

Note: Sigma has also released a replacement for the 80-400, the 120-400mm F4.5-5.6 DG OS HSM
