Questions & Answers

Shopper : what would be best on the 645 Z ,this lens or the 55mm?LAWRENCE C : That would depend on what you're photographing. For instance, longer lenses compress scenes. They are also perfect for portraits. So, if you're shooting portraits or landscapes you'll want the 55mm. If you're looking for an all-around great lens to shoot just about anything except portraits, then the 45mm will be better suited. The 45mm will also allow you to be a bit more creative since shorter focal lengths tend to distort images a bit - buildings lean inward or bow out toward the edges of the lens.
Shopper : Why Did You Choose This?BRITTANY M : I own the Pentax 645Z specializing in portraits and fashion.

I love this bag

I love this lens, especially mounted on the K1 mark2 camera. Portrait photos on P mode are excellent. Just the right amount of bokeh in just the right places. Presently it is mounted on my K3 and again just great results. Excellently produced. I love "old school lenses with these results.

Best Pentax lens for full frame and for any other camera.

Nothing else but to day, this is one of the top three lenses made by Pentax.

Simply wonderful

This is a lense that I often have mounted on one body because the focal length allows capture of landscape details. I favor it because it is quite sharp . Note that this works FF with the Pentax K1. One of my favorite of my ten Pentax lenses.

The Finest AF Lenses

These are film-era lenses with screw-drive autofocus. Pretty quick but make a slight noise. The older SMC coating is also prone to fringing wide-open in high contrast situations. Luckily there's a PP adjustment in your Pentax body to help minimize. Quirks aside, they quite possibly capture the most stunning and vibrant photos on film or your DSLR sensor. Which help explain their continued production and high demand. The FA-77 is the ideal portrait lens. Has that extra degree of subject separation and 3d pop. If you are good at composition, your photos WILL stand out!

Quite simply the best!

The Pentax FA 77mm Limited is quite simply one of the best prime lenses for portraiture that I have ever used. I've used the best lenses from Nikon, Canon, Olmypus, Fujifilm, Leica and Zeiss over the course of my career and if you're looking for a short telephoto prime that is razor sharp even when wide open and renders beautifully smooth bokeh then the FA 77mm Limited from Pentax is a GREAT choice. I also love using this lens in manual focus on Pentax cameras and other cameras (via lens adapter) when shooting video. I always use lenses in manual focus when I shoot video and the focus ring on the FA 77mm is butter smooth and easy to snap into focus. The only "con" with this lens relates to the aging Pentax screw drive AF system when shooting stills. By modern day standards this lens has slow AF like all Pentax screw drive lenses. It's not horribly slow - you can still photograph moving subjects using AF - the AF just isn't as fast as the latest generation lenses with silent AF motor drives built into the lenses.

Perfect

Initially got a bad copy, but the replacement is flawless. AF is spot-on, fit and finish are exceptional. Images pop with amazing 3D clarity and colors, though occasional PF appears in high-contrast situations. A hidden gem in a sea of overpriced, flat-rendering "premium" competitor primes...

Highly recommended

I've only had the lens for a few weeks, but it's terrific. My most successful experiments have been stopped street photographs, delivering awe-inspiring sharpness and a beautiful tonal gradation, and wide open close ups with in focus sharpness contrasting with really lovely bokeh. Others have complained about the lens cap, which is not click on but snug and lined with green felt, falling off. My problem--which is minor--is the opposite. It takes a bit of an effort to get it on and off. Highly recommended

A Pentax Classic

I've felt for years that Pentax lenses are unrated given the line up of superior quality lenses and sharp imaging. The 77mm limited is no exception and is only rivaled by the 31mm and possibly the 40mm Pancake for image quality. This is a must for any Pentax user needing to round out his or her lens choices. In fact, if your being held back by the price, consider sacrificing other lens options for this one which can be used for landscape, portrait and close ups. Pentax only needs to roll out a pro model camera now to really showcase these superb lenses. Don't hesitate. Get one NOW.

One of the best autofous lenes ever

This is one of the only modern autofocus lenses that's built like the classic lenses of old. The contrast and sharpness are unsurpassed. The out-of focus areas ("bokeh") are creamy and smooth, due to the nine aperture blades. Smooth manual focus ring, usable on older cameras as well as the new ultra-electronic ones. Great portrait lens. Perfect for headshots on the digitals, and portraits on the film cameras.
