The Sigma 50-150 a great lens. Very sharp, good AF, f2.8 and an absolute workhorse for me for 2 years. You'll love it.

Oh that's a pity. Surely the numbers are there for a simple mount change if they can make it fit the extremes of Canon and Nikon. I really wonder what Sigma have against Pentax of late.

I don't think it's competing with Canon / Nikon lenses Pentax have to worry about as much as 3rd party lens producers.

Sigma have come out with some stunning lenses over the past couple of years, lenses that have received rave reviews from test sites and users alike (the 35/1.4 is now considered the best 35mm out there bar none) and Tamron too e.g. their new 70-200 is incredibly sharp, AF is very fast and the lens supposedly only just lags a tad in some areas behind those of CaNikon, but at a much lower price point.

Sigma have also just announced an APS-C 18-35/1.8 - wow !

I would think all camera manufacturers are watching those two very closely at the moment.

I've just insured myself, my wife and US$20,000 worth of camera gear for 6 weeks in NZ for NZ$534 with AA NZ, yes the same AA car breakdown group as in the UK, (you can insure for any country and it doesn't matter where you are resident). This was their top level of cover to cover full repayment for all losses, flights, baggage, delays, missed flights (due to connections), medical expenses and repatriation etc. If you require less, or have less equipment, or a shorter trip, then I'd imagine it could be much cheaper. You will need to itemise any equipment over (I think it was) NZ$1,500 per item.

The level of cover is very impressive and even covered all of our car hire accident excesses and also damage up to NZ$6,000, saving us NZ$25 a day in limiting excess to zero in the event of an accident - so paying for all of the insurance !

I compared this to around another 10 different companies (including the famous 'Nomads' - a great travellers insurance service) and although the basic cover was often good by the time you have listed your gear it can get very expensive and with fewer benefits and less cover than this policy.

I've taken a few flights recently and in all of them if they spotted the batteries in my hold luggage (via their scanner when you check-in) then they ask you to open the bags and remove the batteries and then place them in your hand luggage. This was in China of course.

I've used the Vivitar x2 macro TC and it did a splendid job with virtually no noticeable IQ degradation.

Sorry to say but that is identical to the second SDM failure I had with my DA*300, it will fail again - I've just got the 300 back today after it spent nearly one month in Japan !

+1 Bought a grip, used it twice, now it's collecting dust.

OMG - I had totally forgotten I have this lens in the UK (with my daughter). She found it already packaged and ready to go when she moved home last weekend.

So. Any decent offer (over £20 + Shipping & PayPal Fees) will secure this as currently it is a total waste of a decent lens !
