This is a keeper!

I had a Bigma (Sigma 50-500mm), which I used on an Alaskan Cruise. But when I got back I decided to sell it and get this lens (Pentax DA*300/4) because of weight, better aperture, and weatherproof. I found while trekking about Alaska, that my backpack was starting to feel heavier and heavier as the day wore on. The biggest problem was the Bigma, it was the heaviest lens in my backpack.

I had a Bigma (Sigma 50-500mm), which I used on an Alaskan Cruise. But when I got back I decided to sell it and get this lens (Pentax DA*300/4) because of weight, better aperture, and weatherproof. I found while trekking about Alaska, that my backpack was starting to feel heavier and heavier as the day wore on. The biggest problem was the Bigma, it was the heaviest lens in my backpack. Also, while out on a boat shooting photos of whales, I had to be careful not to get the Bigma wet because of the salt spray and drizzle. In a nutshell, I decided to get the DA*300/4 for the weatherproof sealing, larger aperture for better focus in the less than ideal light, and it is much lighter to pack around. I wasn't disappointed in performance either! The first thing that I noticed is - what seemed to be broken focus. Nope, it wasn't broken - it was super quiet! The SDM focusing in this lens is fast and quiet. The lens is sharp, sharp, sharp too! I have a K20D, and pixel peep to see what a new lens resolves. This lens out-resolves what the K20D can show. That's right, the lens is sharper than the camera can resolve. So, when Pentax comes out with the next higher sensor, this lens will work just fine. I can't say what the negatives are, I haven't found any yet. It also works just fine with a standard 1.4X teleconverter. The images show very little degradation (another testament to how sharp the lens is to start with!).

Excellent Lens

By

from Mesa, Az  -  Semi-pro Photographer

It is a prime lens of high quality. Quiet, fast, focus, overall smooth. Everything you would expect for the price. This is a great birding and outdoor lens. The low light usage is limited but logical considering the focal length vs diameter.

My best Lens!

By

from Phoenix, az  -  Photo Enthusiast

This lens is simply the best lens I have ever owned. The clarity and accurate focus is overwhelming. The motor is whisper silent. It is expensive and I really had to think a long time before purchasing a lens that cost more than my first car but worth the money indeed.

I'm glad I have this lens!

By

from Montrose, Colorado  -  Photo Enthusiast

Living in Western Colorado, I try to get out as often as possible to photograph wildlife. In just a couple of weeks time I have captured the wild horses of the Little Book Cliffs and the bald eagles that have returned to the valley to fish the small streams and rivers. This lens has done a beautiful job of capturing the various wildlife on the western slope. By using the 300mm, I didn't have to get too close to the wild horses, thus disturbing them. I am really enjoying the clarity that this lens produces.

Not the cheapest but certainly the best

By

from Mission, TX

This is a great lens. The build quality is superb and the focus and silky smooth. The removable tripod mount is well thought out and the lens handles very well.

VERY Happy!

By

from Friday Harbor, WA  -  Semi-pro Photographer

I don't often write reviews for the photo gear I have purchased, but this lens DESERVED a review, and a very high praise one at that. I am primarily a wildlife photographer so I needed a high quality lens that would get me up close to the action without interfering with the wildlife. I primarily photograph marine mammals so it was very important that I could hand-hold the lens that I purchased since having a tripod on a boat is absolutely useless. While this lens is a bit on the heavy side, it small enough that I can easily carry it around on a boat or on hikes without it being too much of a burden (although I do recommend investing in one of those nifty Cotton Carriers if you will be doing a lot of walking around with this thing). This lens takes absolutely stunning images. The photos are tack-sharp, very nice bokeh, and wonderful clarity. Even when I crop in 100% or even 200% the photos still look fantastic. In short, I am very impressed. The only cons of this lens is the weight (it is a bit heavy, but it will help build muscles ;) ), the auto focus is slower than I would like sometimes however it is still very fast, and the hood can be a real pain to get on and off. Otherwise this lens is all aces and I've attached a photo to prove it.

reach out and touch something

By

from crescent city, ca  -  Photo Enthusiast

This lens is great! Fast auto focus, sharp and accurate. The lens is heavy, but what would you expect in a weather sealed, 300mm lens. You can really reach out and get that impossible shot with this one.

Great telephoto!

By

from Cincinnati, OH  -  Hobbyist/Enthusiast

As I write this review, I'm looking at a image of a Lanner Falcon (native to the middle-east and a favorite of the Arab shieks) in my photo browser that I took on 8/22 at the Cinti. Zoo. The bird show keeper brought out three birds for members of my photo club to shoot. Wish you could see the detail in the feathers of this beautiful bird. I'm still getting used to the lens on my K20D. I used a bushhawk shoulder stock and shot @ 125 to 180th and between F4.5 and 8 (ISO 400). They weren't quiet as sharp as the birds on my backyard feeder, but those were shot on a weighted-down tripod using a cable release. The zoo shots were very good and the bokeh was wonderful! I'm looking forward to using this lens on a tripod at the zoo soon. Well worth the investment. By the way, just sold my older FA* 300MM Pentax [...] for 89% of what I paid for it six years ago! Pentax rocks!
