Sigma 18-125mm F3.5-5.6 DC

Review Date: May 16, 2005 Recommend? yes | Price paid: Not Indicated | Rating: 7 

Pros: Very sharp considerng the range and price (see cons though), great range, Internal Focusing, Light, feels pretty well built..
QC, backfocusing at wide open and wide focal length

For the money and considering the range this lens is amazing.... if you get a good copy... Sounds familiar doesn't it, a lot of people complain about bad QC with various sigma lenses, even EX lenses.

My first lens was very soft on the left hand side... If it was all soft I may have just thought it was rubbish and not exchanged it. But as it was soft only on one side I returned it and they replaced it on the spot... The second sample I got was very good, much sharper than I would have expected. So do not buy this (or maybe any?) Sigma lens from somewhere you can't exchange it....

Even though this sample is sharp I have discovered one other problem, wide open (3.5) at focal lengths from 18-35 it tends to backfocus... beyond 35mm or when stopped down 1-2 stops this problem goes away... I live with it as I know when to use MF and when I can trust AF. It is a problem but considering how usefull the focal range is, and how surprisingly sharp it is when you keep this in mind, I am happy to accept this fault....

Sigma 50mm f2.8 EX Macro 1:1 Lens

Review Date: Apr 25, 2005 Recommend? yes | Price paid: Not Indicated | Rating: 10 

Pros: Smooth creamy bokeh, great colour and contrast, very sharp even wide open once stopped down it is amazing, fantastic value for money
Does extend a bit too far when 1:1

nice ;-)

Sigma 20mm f/1.8 EX DG Aspherical RF

Review Date: Apr 2, 2005 Recommend? yes | Price paid: Not Indicated | Rating: 10 

Pros: sharp, bright, feels well built, wide focus ring
82mm makes for limited range and expensive filters..

This is a great lens, nice and wide, still 30mm on my Pentax ist DS, and bright.... Focuses well in low light, nice wide focus ring which is nice to use if using manual focus...

It is (or at least my sample is) much sharper than people give it credit for... OK it is not as sharp as a tack at f1.8 but most lenses are not perfect wide open, it is defintely stil usable IMO... and it is better than my pentax 28mm f2.8 prime at 2.8 and even if a little soft at 1.8 isn't that better than not getting the shot at all?

Only problem is being 82mm, filter choice is limited and expensive...

I am more than pleased with this lens and have no buyers remorse, would gladly recommend to others...
