Do you really need more than 1 lens? Maybe not--this Sigma 50-500mm F/4.5-6.3 APO DG OS HSM Lens for Pentax covers a lot of ground. The 10x zoom can be used on everything from landscape and portrait photos to sports action and wildlife photography. It uses 4 Special Low Dispersion (SLD) glass elements for optimum color correction and sharpness through the entire zoom range, and a Hyper-Sonic Motor (HSM) provides quiet and high-speed auto focusing. The Optical Stabilization (OS) system allows you to use the lens even off a tripod to capture sharp, clear photos. 

This 50-500mm lens is designed for use with Pentax DSLR cameras--with an APS-C-sized sensor, the effective zoom range is approximately 75-750mm in 35mm equivalent. Note: The Pentax mount tele converter cannot be used with this lens.

Note: Pentax mounts do not have an aperture ring--some functions may not work depending on the camera model.

Note: It is not possible to use the AF and the built-in OS function of this lens when attaching it to film SLR cameras as well as Pentax *ist series and K100D.

Note: When using the OS function of a lens with a camera which incorporates a stabilizer unit, please turn the camera's stabilizer unit off.

    This lens has filled my need for a longer reach, it is so versatile. Going from 50mm to 500mm without having to change lenses is awesome. I have been using it to capture eagles in flight with excellent results. Focus is fast and quiet and you can easily zoom in or out to frame your shot. The only drawback is the weight, but then exercise is good for you. I love it.

    This is not a lens that can be easily handheld or carried. It is a lens to be taken on excursions devoted to photographing subjects that are appropriate for the long reach of the lens. It is too heavy and bulky to carry in the field on extended hikes just in case you might find a use for it. It needs a sturdy tripod designed to handle the full weight of the lens/camera combination.

    The lens has a lock to address the lens creep problem. But the lock is poorly designed. To engage the lock I have to retract the lens all the way. But in that position, the lock will not engage. It is necessary to back the lens off ever so slightly before the lock will operate. Thus what should be a simple one handed action becomes a complex two-handed proposition. I contacted Sigma customer support; they told me that all the lenses work this way. In my mind this is a serious design defect.

    That said, the lens has given me some truly wonderful and amazing photos. Just don't expect great results on little far away birds when using it handheld.

    Comments about Sigma 50-500mm F/4.5-6.3 APO DG OS HSM Lens for Pentax:

    This is my third Sigma zoom lens. And this 50-500mm is a keeper!
    The prior lenses were 135-400mm and 120-400mm. The 50-500mm blows the others out of the water. The focus is much faster and a lot less searching. And the focus is correct with no in camera compensation (Pentax K-3).
    The images you take with this lens are impressive. Everyone else's examples of focus and image sharpness are true and factual. I do not do any post processing with the only exception of bringing out highlights in darker scenes (not a lens issue). This works fine for macro photos, although you are standing several feet from the subject. I shoot photos at 500mm hand held using rapid multi shots, cause they are not all going to be steady.
    I highly recommend this. Skip the others and save your money for this one. The build quality is great.
    The only negative is the weight of this lens, but I hand hold it for hours on end. I do use the lens strap for support when walking.

    Comments about Sigma 50-500mm F/4.5-6.3 APO DG OS HSM Lens for Pentax:

    I was shopping for a versatile long range zoom lens when I stumbled onto Sigma's 50-500 lens. No one else offered a similar product and the price seemed alright. The lens took a little bit getting used to. it is on the heavy side so shooting free hand can be difficult. I use a monopod to overcome this problem. When stationary the monopod offers a solid platform to take amazing shots. I have since discovered that the collapsed monopod acts as a stabilizer when shooting moving targets such as birds in flight or aircraft. The lens focuses very quickly. The lens' "sweet spot" is between 200 and 300mm but the results outside this range are still very good and deliver very detailed photos. Given that when used with a C-sized frame camera the actual range is 75-750mm it is an extreme telephoto lens for a very reasonable price.

    The only thing I don't like about this lens is the lock. One has to retract the lens all the way for it to work.

    This is my "workhorse" lens which is always attached to my camera when I go shooting. As for my pro friends who didn't like the lens at first because it wasn't a "name brand" lens have since changed their tune.

      I bought this lens for my wife. She has started using it for wildlife and bird photography. The only negative is its weight. But using a monopod or tripod has made it well worth the expense.
      I wish there was a case/holster/chest pack that would hold this lens with the camera body attached.

      I absolutely love this lens!!! It has opened up a whole new world for me to photograph. I now can get realitively good shots across the soccer pitch and get up close and personal with wild life that was never possible until now. I know this isn't a prime, and in heavily wooded areas you really need a tripod, but the BANG for the BUCK was tremendously worth it. Oh, this was my Christmas gift from my Fiance`, so that even makes it better. We call it the Casie lens. I am still learning how to use it but hopefully by the end of March I'll be ready for the High Island Migration season here in Texas.

      Comments about Sigma 50-500mm F/4.5-6.3 APO DG OS HSM Lens for Pentax:

      I have been looking for a Sigma 50-500mm for a while as I experienced good results with an older Sigma 170-500 but wanted something that could go wider. The Bigma performs better than the older 170-500, it seems sharper at the long end and the resolution holds up to cropping well. Best results seem to be at f8-f11 when at 500mm. From my initial testing it is just as good at 500 as it is at lesser focal ranges. A slight bit of purple fringe can show up in high contrast areas but is easy to correct in post processing. The Sigma OS gives better results than my Pentax K-5 in body SR.

      Comments about Sigma 50-500mm F/4.5-6.3 APO DG OS HSM Lens for Pentax:

      I have wanted a long lens for wildlife for several years. I finally broke down and purchased the Sigma 50-500 for my Pentax K-7.

      It is big and heavy, but it is very clear at all lengths. Easy to use. I especially like the manual focus override. I am worried about dust and rain, so I will be getting it a "rain/dust coat"

      I have never owned a Sigma lens before. All of mine have been Pentax or Tamron. I am very impressed with the quality. This will not be my last Sigma lens.

      If you want a verstile, long range lens, this is the one.

        I bought this lens to shoot pic's of grizzle bears. I wanted to be as far away as possible, but make it look like I was standing right next to them. This lens will produce those results. I have taken close ups of spring flowers with tac sharp results. As well as shots of my granddaughter riding her bike. The lens focus's fast and quietly. There is no vibration that I could feel. I am thoroughly impressed.
