Product Highlights
  • Guide No.: 178.2' at ISO 100

The Pentax AF-540 FGZ is a professional flash unit that is fully compatible with the entire line of Pentax cameras, from the original 67 to 645N II & MZ-S, MZ-SD or digital *ist, K100D, K110D and K10D series cameras.  It will support advanced flash functions of even the latest digital SLR camera models.

Full manual control of flash output is possible even in slave mode, or use the TTL flash capabilities of the camera it's mounted on to achieve painless exposure with every aperture. The pop-up flash incorporated into many Pentax 35mm SLRs can be used to trigger the AF-540 FGZ wirelessly, and when combined with the MZ-SD or *ist D camera this is done with TTL metering!

NOTE: Off-camera corded TTL or P-TTL flash with the AF-540 FGZ requires two pieces; Hot Shoe Adapter F or Fg (catalog #31022 & 31045 respectively), and Extension Cord F5P or Extension Cord F5PL (37347 & 37349 respectively).

Auto-zoom head covers from 24-85mm (20mm wide-angle adapter included)
Compatible with every Pentax camera, but has special features when used with MZ-S/MZ-SD or *ist series cameras:

    I use this for my 67II medium format and with a K10D digital rig. If you update the firmware for the K10D, the popup flash on the camera will control the AF-540, so this can be used as a key light, with on camera fill. I also have Canon EX multiple flash, and this unit can be added to the mix without problems--pretty easy to proof digital images.

    Slave 2 setting is optical trigger. This makes the flash very versatile. I have been a Canon user for 30 years (for small format) but am really warming-up to Pentax! I plan to buy additional AF-540Z units as background, accent and hair lights--a very portable lighting kit,
    in combination with a Quantum T2. At maximum power, this has got to be a 75 watt-second pop--quite respectable!

    Had it for 8 months without much use ( I have another brand camera and flash) and the circuitry blew out while covering a wedding. Maybe I got a defective one. Because of the problems getting it back to the manufacturer from my country (no local dealer) I just did not bother. I am getting a Metz to replace it.

          I replaced a Sigma 610 with this flash and was surprised at the lack of power. Build quality seems ok, except for the battery door which is flat out lame. The lighting was inconsistent and consequently I'm for a very long editing session from a wedding I shot last weekend. I expected better from Pentax.

                Wireless, easy to mount, learning curve for the newbie, she will use it mostly for portraits and family photos at events. She bought a cheap one a month ago and it has been sent back. This is the real deal.

                Plastic Foot Ruins This Flash

                Comments about Pentax AF-540 FGZ P-TTL Shoe Mount Flash:

                I've used this flash for a couple of years, and today I ordered a Canon 580exII to replace it, for one reason: The plastic hotshoe foot. I've snapped two off of this flash by knocking short light stands over (Its companion 580exII has suffered the same fate multiple times without issue due to the metal foot.) Replacing the hotshoe assembly is $, and after a couple of times it becomes not worth it. Another major con is the fact that Pentax's proprietary sync port on the flash means that you can't connect a pocket wizard to it without using a hotshoe sync port (additional purchase necessary). Other than that, it works reasonably well. The true slave mode is a feature I really wish the 580exII had, and TTL works somewhat well with my K-5, but it's not that great. I'll be keeping mine for weddings and lower-risk shoots where it will stay on or near the camera the whole time.

                Comments about Pentax AF-540 FGZ P-TTL Shoe Mount Flash:

                This is one of the few pro-level flash options for Pentax. It has the capability to work well, but has a few annoying attributes. The flash head has a button to unlock it to pivot, but, in reality, the button only locks the flash from going to a negative angle - questionable value. The flash often doesn't quite nail the exposure with P-TTL. Recycling times could be better, too. On the positive side, once you figure it out, it is easy and fast to manipulate; the battery pack option is affordable and worthwhile, and it integrates well with the Pentax line of DSLRs. However, I must admit I would compare this to the Metz 58 AF II if I were to buy another.

IF I could suggest a few improvements I would say. 1) the design is a bit old fashion 2) There must be ways to make the flash lighter 3) The zoom range is to narrow for the normal user

                    This flash was purchased as an upgrade to the AF-360FGZ and is certainly worth the extra cost.What has really impressed is the nicely enginered flash exposure control, tactile feel buttons,and the tilt/swivel head.Performs wonderfully with my K5 and has taken my photography to another level.Once again great service from B&H.

                      I love all the versatility of this flash. I'm still getting used to it, but so far, I really like it.
                      It is a bit heavy, but I'm kind of a wimp.
                      Other people have complained about the battery cover. It does feel kinda cheap compared to the rest of the piece.
                      When I first got it, it didn't work so well - inconsistent. But then Allen suggested I try different batteries, even tho the ones I used were brand new. I switched them out, and it's been great ever since. So... if something seem quite right, try switching the batteries.
                      I gave it a 4 out of 5, just because I haven't used it long enough to say if it gets a 5 - it may very well.

                      Works great. Great build quality, more user friendly then the Metz options. Powerful and feature rich. Wish you could zoom more then 85mm and a broader power range would be nice. All in all, the best option for pentax users.

                        I have been meeting with other photographers recently and we started with some DVD's about lighting with flash. I couldn't wait to upgrade my equipment as I learned. The AF-540 is working just like they described and as is on the DVD.

                            I am a part time photographer, and this AF-540 is great. I wish that I had purchased it sooner. I was looking for a cable for my Quantum pack. I found one from China for only $20.00. Quantum does not make this simple cable, for my Pentax camera.There is one thing that I do not like. The battery compartment is very flimsy and not very strong. I have the feeling that in a short period of time will break off. This is the reason for this cable.
