Sigma Lente Autofoco 70-300mm f/4-5.6 APO DG Macro para Pentax AF

Comments about Sigma 70-300mm f/4-5.6 APO DG Macro Autofocus Lens for Pentax AF:

Don't get me wrong the lens does what it's meant to do but it's just pretty lack lustre... It performs pretty bad in low light and just looks plain ugly.
I made the mistake of purchasing this over the Pentax and I regret my decision. Included case is nice however.

Picked this lens up to get sharper telephoto shots for sports and wildlife. Lens has exceeded my expectations! Pictures appear very warm, clear and most importantly sharp. May struggle a little in low light but otherwise great zoom range and picture quality for the price. Macro shots are particularly impressive!

Used it outdoors at a Kite festival, and worked wonderfully with my K-5. No CA detectable at 300mm, and well fast enough during Washington State's cloudy skies.

Comments about Sigma 70-300mm f/4-5.6 APO DG Macro Autofocus Lens for Pentax AF:

It is amazing how well this lens captures images. The equipment freaks may lament that it dose not have the hardiest of components that well may not hold up under extreme professional use, but the images are excellent! The price of this lens is so reasonable, you can't ask for more! And isn't that what photography should be all about...great images!

Rundown: I am an amateur photographer/ film maker and frankly this lens is amazing. I had previously been using only a 18-55mm lens and the capabilities of the zoom lens is just outstanding. Being able to rapidly switch between 70mm and 300mm is just great! You can get super clear semi-wide-angle shots and even better close ups.

Build: The lens feels very solidly built, it has enough heft to make it feel like your holding something well built, but it's not so heavy that it feels like you are carrying around a brick. Plus the matte finish on it is great, as with the large focus ring and zoom ring.

Picture Quality: This takes amazing photos, they are very sharp and generally breathtaking. Now this is just from me looking at the photos (not testing them rigorously). It gives you the amazing DOF control that most tele-photos offer. The only down side being that you can't have very large aperture's due to the nature of the lens (unlike a prime lens). But what you lack in technical ability you gain in this lens being a perfect travel lens, and is an all around versatile beast.

I purchased this Sigma lens several years ago after my Pentax DA 50-200 ED disappointed. I've used it on both my K100d and Kx with excellent results, although it feels better, and seems to take better pictures, with the larger, heavier and 6 mp K100d. It stays mounted on the K100d, and this is the camera I use around the farm, and for pictures of other peoples horses and mock macros. I keep a good point and shoot in the bag for instances when the 70mm is just too much lens. The combination is not that great for a walk-around, too heavy and too large, and for that I pick up the Kx and the 50-200. Forget landscapes, of course. Overall, an excellent lens.

Comments about Sigma 70-300mm f/4-5.6 APO DG Macro Autofocus Lens for Pentax AF:

I asked for this lens for Christmas from my wife. My hobby is taking a lot of wildlife pictures. I had an older Pentax 300 zoom. My pictures were out of focus and dark. This lens is great. I can get really close with my k200. The pictures are in focus and they are plenty bright. It is not too heavy. Holding it for a long time to get that perfect shot is not that straining. However, it does not seem so light weight that it feels cheap. It really feels durable and I love the finish on it. The finish is textured so that it doesn't feel like it will slip out of my hands and it is matte so that it isn't too shiny when out taking shots of wildlife. I have just started to play with the macro setting on the lens but so far it seems to work pretty well. I gave it four stars because it is a great lens for the price. I know that if we could afford a more expensive lens I would get even better pictures. Even so, I think this is a great lens that I can afford. I recommend it for any of you that want better pictures but don't want to break the bank.

I'm using this lens as a casual alternative to my pro lenses and I'm pretty impressed. All the way out to 300 it's a little soft but generally edge sharpness and intermediate sharpness is really good. For [$] you don't have to worry about ruining a $1000 lens if there is a mishap while shooting. I recommend this lens to photographers with all levels of expertise.

I love using this lens on my Pentax Digital camera. It has a good overall range, and the results are sharp and crisp. The Marco is easy to use once you read the directions. I have gotten some beautiful flower and bird pictures with it. I would recommend this product.

Used for wildlife and candid photos of people and distance scenes like glaciers and distant valleys.

Comments about Sigma 70-300mm f/4-5.6 APO DG Macro Autofocus Lens for Pentax AF:

I like to take shots from far away so people will act normal when they see a camera. It gets the photos I want and its light weight.

I wish it was a little easier to put on the camera. It could just be me though & I wish it fit in my bag with my other things.

Over all luv it!

Comments about Sigma 70-300mm f/4-5.6 APO DG Macro Autofocus Lens for Pentax AF:

Great value. Amazing lens. What can I say? it fits all my needs at the moment. I have recently gotten into photography and it enables me to take crisp photos even at the 300mm range. Highly recommend to anyone even considering it! Also, have not yet come across this 'purple fringe' stuff that some people talk about.

I'm using it with a pentax k2000 and it performs flawlessly.Cost is much less than similar pentax lense

Comments about Sigma 70-300mm f/4-5.6 APO DG Macro Autofocus Lens for Pentax AF:

The sharpness of this lens is always a pleasure to see when I'm processing sports pictures. Enlargements are crisp and contrasty.

Although the macro button is a bit difficult, the macro results are also better than expected.

A very, very good lens for surprisingly little money.

Comments about Sigma 70-300mm f/4-5.6 APO DG Macro Autofocus Lens for Pentax AF:

I use this lens for Kids Sports, General photography, Close up photography. It is nice and sharp and throughout the range, and focuses fairly fast in daylight. Because this is an average speed lens, don't expect good low light fast focusing. This is a great outdoor lens, and was made for good daylight performance, which it does deliver. The color quality is very good too. If you need a good long tele-zoom for inside..GET THE F/2.8 70-200!

Comments about Sigma 70-300mm f/4-5.6 APO DG Macro Autofocus Lens for Pentax AF:

I love this new lens and I am getting some amazing pictures with it. I am not a professional but I know what looks good and others have comments on the quality of the photos with this lens. I just recommended your company a friend who wants to buy new camera equipment. [...]

Comments about Sigma 70-300mm f/4-5.6 APO DG Macro Autofocus Lens for Pentax AF:

Have had the lens for a month now and have used it at car races and for wildlife shots. Lens works great, good clarity on the shots, zoom works great. I have it on my Pentax K2000D camera body. I have two Sigma lens, and am very happy with both of them.

Comments about Sigma 70-300mm f/4-5.6 APO DG Macro Autofocus Lens for Pentax AF:

I use this to shoot basketball and swimming and find myself switching to manual about half the time. When it is in focus it's sharp, but it doesn't move as fast as my lost Pentax 55-200 and it doesn't let you fine-tune the focus manually as a Pentax would. However, when the subject falls within the depth of field I get crisp results. The aperture is a little slow for indoor basketball - I'm forced to shoot at ISO 3200. If you're willing to manually focus when shooting sports and can live without evening shots, you'll be very pleased with this lens.

Comments about Sigma 70-300mm f/4-5.6 APO DG Macro Autofocus Lens for Pentax AF:

I use this lens primarily for nature photography and for sports (dragon boat racing). I have been very pleased with this lens - it is lightweight,covers a useful telephoto rage, and delivers consistently sharp images in both tele and macro modes. On my K10D,it focuses efficiently and reasonably quickly, with no appreciable delay or hunting - its a bit slower on my ist DL but the K10 does have a much better focusing system. The marco switch took a little getting used to - my Sigma 28-200 doesn't have the macro switch but is also a much heavier lens and a bit less sharp than this lens at the extremes. With the 70-300 lens, there is no lens creep either (it doesn't grow in my camera bag). I have a number of both Sigma and Pentax lenses for my cameras and am pretty picky about image quality. All-in-all this is a great lens for the money.
