Sigma 300mm f/2.8 EX DG Lens for Pentax USA

You Pay: $3,399.00

The Sigma APO 300mm f/2.8 EX DG lens is an ultra compact Apochromatic telephoto lens with a fast f/2.8 maximum aperture which incorporates two Extraordinary Low Dispersion glass elements to reduce chromatic aberration to a minimum. It incorporates internal focusing which enables responsive and fast autofocus speed. A detachable tripod socket and rotatable drop in filter holder are also included.

The improved DG lens design corrects for various aberrations. This lens is specially coated to get the best color balance whilst cutting down on ghosting caused by reflections from the digital image sensor. The lens provides the utmost correction against lateral chromatic aberration which is a serious problem for digital SLR cameras.

With the use of the optional Sigma APO teleconverters, this lens can be used as a 420mm f/4 AF ultra-telephoto lens with a 1.4X EX teleconverter, or a 600mm f/5.6 AF ultra-telephoto lens with a 2X teleconverter.

Two ELD glass elements reduce chromatic aberration to a minimum and also ensure sharp, quality images of high contrast

A drop-in 46mm filter holder in the rear part of the lens barrel can be rotated to facilitate the use of filters, including a polarizing filter

    Comments about Sigma 300mm f/2.8 EX DG Lens for Pentax:

    I spent the weekend working with the new lens. It is fast in auto focus and I didn't miss a shot when trying to photograph snow geese! Wish I had bought the doubler for it.

    Comments about Sigma 300mm f/2.8 EX DG Lens for Pentax:

    This lens was purchased because I needed a long, low light lens and pentax offers nothing at this focal length with a constant f/2.8 aperature. So far I have used this lens mostly for photographing wildlife. I have to say I like everything about this lens. It's built like a tank. The lens hood is easily removable and is stored inverted on the lens. This lens uses drop in filters and a CPL is included. The whole thing comes packed in a padded nylon carrying case with a vibration spacer. Ok, it's packed nice and it looks great but how does it perform? The photos I shot with my K20D were razor sharp even at 100% crop. I was very pleasantly suprised on just how sharp this lens is. I am totally happy with this purchase.

    Not what I expected...

    By HawaiianOnline

    Pros

    • High Quality

    Cons

    • Expensive

    Best Uses

    • Birds, sports, low light

    Comments about Sigma 300mm f/2.8 EX DG Lens for Pentax:

    This wasn't what I expected.

    It's even better!!! The AF is very fast on my K10D compared to my Sigma 50-500. It's much much sharper, even with a 1.4 TC. I highly recommend this lens.

    The only bad things about it is the weight and the cost. Then again, this kind of lens needs a monpod, or better yet, a Berlebach wooden tripod with appropriate head.
