The Pentax FA 45mm f/2.8 Lens - Compact & Sharpfrom Pentax FA 45mm f/2.8 Lens - Compact & Sharpis a moderately wide angle lens with a 35mm format equivalent focal length of 35.5mm and a 63 degree angle of view. Used by many as a substitute for the 75mm "normal" lens it's a favorite of street shooters and wedding photographers alike and also ideal for landscapes, groups, or interiors. Its fast 2.8 maximum aperture is brighter in the viewfinder and allows low light shooting without hiking up the ISO, renders artfully blurred backgrounds and permits higher shutter speeds in standard lighting conditions.

A lens hood is included to reduce flare and ghosting as is a lens case.

Related Questions and Answers

Q: 1. What is the length of the tripod collar?

A: Almost 4 inches (almost 10 cm) long and hangs down 1.75 (4.5 cm) inches from the lens.

Q: 2. I really love my K3 and do pet photography with it. I need a good zoom that's quick on AF. The Pentax smc PENTAX-DA* 50-135mm f/2.8 ED (IF) SDM Lens just doesn't autofocus quickly enough.The web page for this new Pentax 70-200 says The Quick-Shift Focus System allows you to first use autofocus to acquire general focus on a subject, then instantly refine your focus position manually without the need for an AF/MF selector. Is this Pentax again not being able to pinpoint focus the way Canon, Nikon, Tamron and Sigma seem capable of, or do we have a genuine capability here for instant lock on moving objects equivalent to say the Tamron 70-200?

A: The new 70-200 is a fast lens but so is the 50-135mm lens. Both are f/2.8 which helps the focus speed. But the cameras focus system does have a very large part to how fast and accurate it can focus.Just to compare the K-3 has 27 Phase Detection autofocus points and the Nikon D7200 has 51 Phase Detection points and 15 cross-type focus points. So in most cases the Nikon Model will focus faster and more accurate.

Q: 3. Under listed specs, only ASP-C is the compatible format. I thought FA lenses were native 35mm format. Is the information posted re compatibility accurate?

A: Yes, the Pentax HD PENTAX D FA* 70-200mm f/2.8 ED DC AW Lens would be compatible for use with full-frame cameras. As the lens was released in 2015 and Pentax's full-frame camera was not announced until 2016 (all previous DSLR cameras being APS-C cameras), our website did not indicate which Pentax lenses were full-frame compatible. It is listed under the Product Highlights on the lens' webpage, and our website will be updated soon listing which Pentax K-mount lenses would also offer full-frame coverage.

Q: 4. Who makes this lens?

A: The Pentax HD PENTAX-D FA 15-30mm f/2.8 ED SDM WR Lens is manufactured by Pentax.

Q: 5. Is a case included?

A: It does come with a soft case, but I don't bother with it. I have a backpack built for camera gear that I keep it in.

Q: 6. Is this lens ideal for astrophotography?

A: It is a nice one for it. It depends on what you are trying to capture. I used it this summer to catch a small portion of the tree line along with the sky. I also used the D FA*70-200 to capture a different perspective. I use this lens primarily for architecture and real estate. It will do nicely if your main need is for astrophotography.. The real key to star and sky shots is the astro tracer function in the k3 and k1, though (I shoot with the k1). You will absolutely love this lens.

Q: 7. Is the removable part of the tripod collar compatible with the Pentax DA 300 f4? I lost that part of that 300mm lens.

A: The tripod collars are not compatible. They are two different lenses.

Q: 8. Is this a variable aperture lens? Meaning will the aperture change when I zoom in or out?

A: The Pentax HD PENTAX D FA* 70-200mm f/2.8 ED DC AW Lens is a constant aperture lens, not a variable aperture lens.

Q: 9. Is the silver part of the lens on the silver version made out of metal or it is plastic coated with silver layer?

A: The Pentax HD PENTAX-D FA* 70-200mm f/2.8 ED DC AW Silver Edition Lens is manufactured from a machined aluminum barrel and has a finely textured finish. The silver finish is simply painted aluminum metal.

Q: 10. Does internal focusing shorten the focal length slightly like with the 60-250?

A: that's a little above my technical 'expertise.' i'm just beginning to get familiar with the lens myself

[f/2.8] This is what a medium tele zoom should be!! 5

[63°] Quite honestly the best lens I have ever shot with! It creates stellar images, is built like a tank, and feels awesome. Pentax hit a grand slam with this one! 5

[45mm] I bought this for use on the K-1 and love it. Image quality is excellent from corner to corner up and down the zoom range (even at 200 and wide open), focus is silent and quick, it's a pleasure to use, and built like a tank--this thing will survive the zombie apocalypse. And that's really the only downside: this is not a lens you just casually throw in your bag or carry around. No question, it's the best Pentax zoom I've owned, and my second favorite portrait lens behind the 77 Limited. Though this lens doesn't have the vignetting or purple fringing of the 77 and is certainly technically better, I still think I slightly prefer the tones, bokeh, and 'character' of the 77 (though that could be just because I'm used to it). While that lens will still have a place in my bag, no doubt, the flexibility of this beast really goes a long way and the image quality is absolutely first rate. Highly recommend to anyone thinking about it--it's a good addition. 5

[0.15x] The product is great. Although weight is larger but is a great lens. I got it a few days yet but very happy. 5

[Pentax 645] So far I've used this lens for sports action photography, and I plan to use it for a few portraits down the road. Although I paid a hefty sum for a hefty lens, I'm glad it has features the 70-200mm f/2.8 Tamron does not: weather sealing, internal zooming (no telescoping action), and DC motor for faster focusing -- a must for fast-action burst shooting. I also read about sharpness issues with the Tamron. It's significantly less expensive, and a bit lighter/smaller, but you get what you pay for, I guess. This Pentax lens produces extremely sharp photos, even at f/2.8. Like others have said, it's built like a tank, but it can be hand-held. Built to last and get the job done in any conditions. 5

[45mm] This is a great lens. The focusing is fast and spot-on. I also used it with the Pentax 1.4 TC and I noticed no difference in focusing speed on birds in flight or on stationary objects. It is a real pleasure on the K-1. It's competitor is the Tamron 70-200 but I wanted the Pentax because the screw-drive Tamron is slower to focus. The only negative is that the Pentax is heavy, but built like a tank. I used it hand-held but it has a solid tripod mount. 5

[Autofocus] The first thing you will say when you open the box is "Wow". This is large, heavy and solid. The next thing you will see, is how incredible the image quality is. Another "Wow". I was a little put off by the price until I seen what this is capable of.� It is Laser Sharp, Rating a 9.9 for sharpness in the Pentax Forums. Fast focus, Quiet, Sharp and Very Well built. No regrets, I love this lens. 5

[1.58 lb] I had a chance to shoot few hundred pictures with D-FA* 70-200 on my K5-II this weekend. I am truly impressed. The lens is very sharp wide open, and autofocus is very accurate. Color reproduction, out of focus areas - everything is beyond my expectations. Honestly, I've not seen such image quality from any Pentax zoom (and even many of the primes) ever. The build quality is very high, nothing to complain about. I really like that the tripod support is double-purposed as a carrying handle, it's very convenient. The only thing I'm not quite happy with is the weight. The lens is really heavy, I'd recommend using a monopod with it. 5
