The Best Lens Options for Your Pentax DSLR

So if you are like me, you own a Pentax DSLR. You love your camera but the lens selection is paltry compared to Canon or Nikon and of course you hear photographers tells you that there isn’t the good glass to go with Pentax.  Even many local camera shops don’t have a great section despite them selling a lot of Pentax K-3 and K-5 IIs cameras in the last year.

So what do you do?  First of all you take a look around online and see what is there.  If you are reading this page, there is a good chance that you are doing just that.  To help you with your search, I have listed around 25 lenses that would all make great additions to any photographers bag.

If you have no idea which lens you want to purchase, ask your local camera shop for advice or check out this video from Pentax.

Ricoh has more about the available Pentax lenses here.

So the next time someone tells you there are not great lenses for the Pentax cameras, remind them of what is out there.  There is some amazing and professional quality glass for your camera.

Each link on the post goes to Amazon.com which offers you some purchasing options and price for each lens.  Since lens price is often moving, it’s easier to check them out there.

Normal Lenses: In photography and cinematography, a normal lens is a lens that reproduces a field of view that generally looks “natural” to a human observer under normal viewing conditions, as compared with lenses with longer or shorter focal lengths which produce an expanded or contracted field of view that distorts the perspective when viewed from a normal viewing distance.

The lens also incorporates a brass-made bayonet mount, to further reinforce the lenses durability and resistance to wear and tear over time.

The minimum focusing distance is the same throughout the focal length of the entire zoom range, and provides a maximum magnification ratio of 1:2.9. As an added benefit over fixed focal length macro lenses, the size and framing of subjects can quickly and easily be adjusted by rotating the zoom ring. For even further convenience, at each focusing distance on the side of the lens barrel, the maximum magnification ratio is also displayed.

For high image quality, you know you’ve got to have high quality glass, and Sigma has incorporated their Special Low Dispersion (SLD) glass element into the 18-250mm. In addition to the SLD element, three aspherical lenses, including a double-sided aspherical lens, have been used in the lens’ construction–offering excellent correction of color aberration, for better clarity and quality of images throughout the zoom range.

A Super Multi-Layer Coating has also been employed to reduce flare and ghosting with this lens. This makes it resistant to strong incident light, such as backlight behind a subject, providing sharper, high contrast images even shooting into a light source. To prevent internal reflections from occurring, the included petal-type lens hood can be attached in order to block out extraneous light.

For a lens that offers a wide-angle to telephoto focal length, and the ability to zoom-in with macro photography, Sigma’s 18-250mm F3.5-6.3 DC Macro HSM made for Pentax cameras is more than a match. Whether you’re on a macro product shoot, a walk in the park, or have a wedding to go to, this lens will help you shoot high quality images in any situation.

Pentax smc DA 18-270mm f/3.5-6.3 ED SDM Lens

Pentax smc 18 270mm lens 1 1358880197

The Pentax smc Pentax-DA 18-270mm f/3.5-6.3 ED SDM Lens is an all-encompassing zoom lens, featuring a 15x zoom rangefrom a wide 18mm to a long 270mm (equivalent to 27.5-414mm in 35mm format). Benefitting the long reach of this lens, two extra-low dispersion elements have been incorporated into the lens construction to help reduce chromatic aberration and improve overall image clarity. A minimum focus distance of 1.6′ across the entire zoom range also makes this lens an effective tool for macro and close-up work.

Telephoto Lens: In photography and cinematography, a telephoto lens is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. This is achieved by incorporating a special lens group known as a telephoto group that extends the light path to create a long-focus lens in a much shorter overall design. The angle of view and other effects of long-focus lenses are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as telephoto lenses although this is technically incorrect: a telephoto lens specifically incorporates the telephoto group.

Telephoto lenses are sometimes broken into the further sub-types of medium telephoto: lenses covering between a 30° and 10° field of view (85mm to 135mm in 35mm film format), and super telephoto: lenses covering between 8° through less than 1° field of view (over 300mm in 35mm film format).

Wide Angle Lens: The terms “wide-angle” and “telephoto” are based on the different angles of view they provide when compared with a normal lens. A wide-angle lens captures a wider angle of view than a normal lens does. There is no single wide-angle lens, but rather a variety of lenses that give wider and wider angles of view, some of which are classified as super or ultra wide-angle lenses, and the widest of all – fish-eye lenses. Lenses considered to be wide-angle include the 35 mm, 28 mm and 24 mm varieties, with the 28 mm being the “standard” wide-angle lens. Super wide angle lenses then take over, and run from 20 mm to about 13 mm.
