Perhaps a couple of portable hard drives and a rented safe-deposit box at the local bank branch would be the ticket. Keep one in the bank box and one at home, swapping them as needed. Although I should add that while bank fires are uncommon, my bank had a fire at one of it's branches (not mine), but apparently there was no damage to contents of boxes, although the contents were not described.

AF-540FGZ off-camera flash

Yes, in answer to your question. You need a cable like this one -- Vello Off-Camera TTL Flash Cord for Pentax Cameras (3') OCS-P3 -- which has the same contacts as those in the hot shoe. The flash tethered to the camera acts as the Master/Controller and will trigger the second (or more) P-TTL flashes as long as the latter can see the flash coming from the tethered one. It's quite reliable indoors; outdoors should work as well, provided the distance is not that great (up to 4 meters according to the manual). You can always orient the body of the off-camera flash so that it's sensor is pointing toward the master/controller and the head aimed at the subject.

I've got the AF540FGZ II and YN-585EX and they work well together. You can aim the Master/Controller flash head at the off-camera slave if don't want it to contribute light to the subject. Gels shouldn't be a problem and the set-up will work with umbrellas because the slave is out in the open, but softboxes may be another matter.

Your Ricoh / Pentax product developed a fault, and you've lost faith in the brand...

I don't wish to get into a back-and-forth on this issue, but the part number of the junk solenoid in my K-50 may be the same as in my K-x, but it is not the same part. The plastic in the junk solenoid is green. The plastic in the K-x solenoid is white. The green one is made in China. The white one was made in Japan. The white ones seem to last as the should. The green one seems to fail way, way to often. Pentax engineers have had years to figure this out.

The bottom line here is that Pentax has to know that the green solenoid fails too often to be sheer coincidence. They did nothing about it. They continued to produce cameras using this junk part. It's one thing to be unaware of a part that fails to meet expectations. It's quite another to turn a blind eye to the problem.

I too use the K-50 (on rare occasions) with lenses with an aperture ring and use the green button for proper exposure, but that isn't exactly what the the camera was designed for. If you find joy in a broken camera, I'm happy for you. I'm with the crowd who think Pentax blew it when it comes to customer support.

I have a defective K-50. It went bad with about 3,500 clicks from an aperture block failure. I procrastinated and didn't get it fixed while it was still under extended warranty. My mistake there, but the camera is nevertheless defective with a bad solenoid. Now if my camera was the only one, or one of relatively few K-50s that came down with aperture block failure, I'd be sanguine about the matter. Stuff happens. I get it. After all, I've got a K-3II, a couple of K-01s, and my wife's K-50 is still working fine. And, I've had a K-20D and a K-x that worked without a hitch. But, and it's a big but, Pentax seems indifferent about the issue. After all, it started with the K-30, then the K-50 and K-500, and then the K-S1, and then the K-S2. All of which suffer with the same problem -- a junk solenoid. Maybe, it's even in the K-70. Why does Pentax keep using the same part? They know it's poor quality. They know this isn't a random parts failure. Pentax's response to date has been dead silence. Kinda like their response on the SDM problem.

How does this bad solenoid issue together with Pentax's lack of response regarding it comport with the comments from a Pentax executive at CP+ that "I think it would be good if in the future PENTAX would be the brand through which we could communicate the sheer joy of taking pictures by enhancing services as well as the impression given to more discerning customers with the idea that photography is a great pleasure?" There's no joy in a broken camera, whether it be an entry-level model or a top-of-the-line.

You might want to take a look at the YN-585EX flash. It is a Pentax-compatible P-TTL flash, but doesn't do High Speed Sync if this is important to you. While the flash can't act as a Master/Controller to your AF-540FGZ II, you can use the AF540FGZ II as the on-camera Master/Controller for YN-585EX flashes in P-TTL mode. This is all done optically, so the Slave flashes must be able to see the flash coming from the Master/Controller. At $79 (here in the US), the YN-585EX is hard to beat (unless you plan on eventually switching to radio triggers).

The shutter count on my K-50 today is 4023. The camera suffers from aperture block failure. I've been using it lately with lenses with an aperture ring and the green button, so its not a total loss, but it is kind of a pain. I'm not sure what the shutter count was when the failure occurred.

My opinion on this subject is that Pentax's response to this problem, a poor quality solenoid, that affects five camera models at least has been a big zero. This is clearly a manufacturing defect that the company should have done something about. I've got a K-3II, so the K-50 isn't my only camera, but I sure am hesitant about putting more money into Pentax.

If you're using two identical lights and If the second light matches the set-up of the first light exactly, you gain one stop of exposure. That is, if one light gave you the desired exposure at f/4, then when adding a second identical light you would use f/5.6.

If on the other hand, your lights have different guide number or you have them at different power settings or different distances from the subject, the math you're dealing with is something like Pythagoras' theorem (A Squared plus B Squared equals C Squared). For example, if you needed to use f/8 when using one of the lights for your desired exposure, and the other light if used by itself required f/4, then when firing both together you would use f/9 (8 Squared (64) plus 4 Squared (16) equals 80, and the square root of 80 is 8.94 or about 9, so f/9 would be the aperture to use). You can figure the combined Guide Numbers of two flashes similarly. For instance, with two flashes, one GN 56 and the other GN36, when used together have a Guide Number of 66.57 (56 squared plus 36 squared equals 4432, and the square route of 4432 is 66.57).

Regarding refocusing between shots, if the camera is on a tripod and at a fixed position and you always return to the exactly the same spot, then once the camera is in focus, it will always be in focus. Simply focus the camera before putting it into self-timer mode. If you move about between shots however, then you need to be concerned about refocusing. I don't have a K-70, but I doubt that it refocuses when using the self timer. I know my K-3II doesn't.

Regarding P-TTL vs. manual flash, again if everything is in the same position between shots, you won't need P-TTL, which is most useful when the distance between the flash and subject is constantly changing. You can calculate how to set up a flash in manual mode by using the flash's Guide Number (GN) and using a simple formula -- GN divided by f stop of lens equals distance of light to subject. Or, GN divided by distance equals f stop. The GN changed based on ISO, zoom and power settings of the flash so these things need to be taken into account, but the flash should come with a chart that factors in these things.

You can use an on-camera flash, either a built-in flash or one in the hot shoe, to cause an off-camera flash to fire at the same time in manual mode. That is, if the off-camera flash has an optical Slave mode. The off-camera flash fires whenever it sees the on-camera flash fire. If you have the off-camera flash buried inside a softbox however, it might not see the flash from the on-camera flash. Also, you could use inexpensive radio triggers to fire an off-camera flash by using a transmitter in the camera's hot shoe and a receiver on the flash.

Off-camera P-TTL flash would require a couple of flashes that have P-TTL capability, with one mounted in the hot shoe being able to act as Master or Controller.

F/1.6 is 1/3 of a stop smaller than f/1.4, so you're right, you probable wouldn't notice the difference. Or, give it one less click or one more click on the speedlight dial depending on whether you're closing or opening the aperture.

You need to memorize the full aperture f stop sequence. It's not hard == 1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32. Each of these values is one stop difference. If your camera is set to 1/3 stop increments, you can simply set one f stop there and then count the clicks until you reach the one you want.

Bruce, first off, your counting is wrong with regard to adjusting the main flash. You only lowered the flash's power output by two stops, not three. Also, you're using whole numbers for the flash output, when these numbers are actually fractions. When you say "8>32," you should be saying 1/8 power to 1/32 power. So when you adjusted the lens aperture 3 stops from f5.6 to f2, you should have reduced the flash power by three stops as well, and that is from 1/8 to 1/64 power (1/8 to 1/16 is one stop, 1/16 to 1/32 is another stop and 1/32 to 1/64 is the third stops).

Since your flash is set for adjustments in 1/3 stop increments, you merely would have had to count 9 clicks to lower the flash's output to compensate for opening the aperture by 3 stops.



Here again you're not adjusting the speedlight correctly. The correct value is 1/32 power.
Starting with the lens at f8 and the flash at 1/2 + 7 and then reducing flash output by 4.7 stops we get:
1/4 + 7/10 (1 stop down)
1/8 + 7/10 (2 stops down)
1/16 + 7/10 (3 stops down)
1/32 + 7/10 (4 stops down)
1/32 (4 and 7/10 stops down)
The easiest way to do this is simply to count the clicks. Three clicks for each full stop (3 x 4 = 12), plus 2 more clicks for the 7/10 stop for a total of 14 clicks on the speedlight dial/button.

Hope this helps.

Yes, as I mentioned above, simply count off the corresponding number of clicks on the flash's dial. F8 to f4 is two stops, so lower the flash power by two stops, or six clicks since your flash's output is set to adjust in 1/3 stop increments.

Along these lines when using the viewfinder one could set up a user mode that included the appropriate exposure compensation and other preferred camera settings. That way you wouldn't have to constantly fiddle with -/+ adjustment when going between the liveview and viewfinder.

Has anyone used these folks...

https://www.pentaxcamerarepair.com

$100 seems fair and it is a pretty easy repair from what I'm reading. Unfortunately I fly to China in 2 days so I'm going to have to wait and hope the camera is still usable on the trip. I'll take my Km as backup and I also have a a Canon Elph 350 (20mp) .



There's lots of info regarding the fix for this problem in the K-30/K-50 forum. Regarding the repair by this person, it's said that he files/sands the problematic solenoid horseshoe and that this isn't a permanent fix. That is, the problem can return and possibly cause additional problems. He does however give a one-year guarantee.

If you have a lens with an aperture ring, you can set the aperture on the ring and then use the green button to set the appropriate shutter speed to get proper exposure. You need to make some menu adjustment to make this work.

Kobie, thanks for the videos. You mention in the first video something about using HSS in both P-TTL and manual modes. Can you expand a bit about HSS in manual mode as there was nothing in the video about this?

Also the specifications for V6II say it supports power sync (hyper sync). Is this something that works with the Shanny or only with a Cactus flash like the RF60x?

Check the hot shoe on the camera, ensuring that no foreign material is lodged in it. Also make sure that the flash is seating properly in the hot shoe. It may be that the pins on the flash and camera are not lining up properly/completely, so give the flash an extra firm push into the hot shoe.

3rd Party Flash for Pentax that HSS in Manual Mode (from the hot shoe)?
Posted By West Penn
Replies: 63

Just a couple of final points on this. If you want to shoot HSS at 1/1000 and f/2.8, you simply have to look in the manual for what distances are possible. You do that by dividing the guide number by the aperture to get the maximum distance the AF360FGZ II can be from the subject in HSS mode. And, the answer is -- 9.5 divided by 2.8 equals about 3.4 meters. That's the max distance with a bare flash. It's that simple. Use a calculator! Now if you put a diffuser on top of the flash you are further limiting the distance you can be from the subject. You simply need to figure out how much light you're loosing by using the roundflash diffuser and then factor that into the equation. If you're losing one stop of light with the diffuser, simply divide 9.5 by 4 (it's like now shooting at f/4).

Regarding that Godox tt350p flash, it has the same guide number as the Pentax 360FGZ, so it's unlikely that it will do better in HSS mode even if it's possible to do HSS in Manual mode. It's simply the nature of HSS. At and below sync speed there can be up to a full power blast of light. In HSS, there are multiple flashes, each of which is a fraction of full power.

Posted By West Penn

The truth be told, this whole issue could be understood fully (hopefully) with pencil and paper. By way of example, take the Sunny 16 Rule, or shooting at f/16, ISO 100, and 1/100 sec on a bright, sunny day. Then if you wanted to underexpose ambient by one stop and use an aperture of 2.8 on that bright sunny day, you'd need to use HSS mode and your shutter speed would need to be increased by six stops (one stop for underexposing the ambient by one stop and an additional five stops to compensate for opening the aperture those five stops from f/16 to f/2.8). Increasing the shutter speed by six stops take us from 1/100 sec to 1/6400. If we use 1/6000 sec which is close enough for this example, we find that the GN for that speed is 4.3. Using the GN formula, we'd need to place that bare speedlight about 1.5 meters or less in order to use HSS. If add a diffuser, you'd need to place the light even closer.

If you step up to the AF540FGZ II, you'd need to place the flash about 2.25 meters or closer to the subject.
