I'm back - still going to be sparse visits - but after I retire in another 73 days? I get a life! I'll try to get a photo or two in here from a recent weekend trip to a Louisiana sugar cane plantation - pretty much restored/preserved to how it was in the 19th century.

Focus for birds

From someone who doesn't do a lot of bird shooting.... Set the shutter speed using at least twice your focal length, set the aperture to f8 or f11 if you can, adjust ISO to match lighting conditions. Turn on manual focus, and activate the depth of field preview (on the camera on-off switch on the K-3 series) and aim at your predetermined target point. Find the range of acceptable focus, then set the lens in the middle.

I'm now able to ignore all the variables except composition at possibly the sacrifice of a bit more noise in my image.

Been really busy with work all summer & fall. I finally pulled the chips out of my K-3 and worked a bit with this one. 55-300 and heavy crop from about 100-125 feet away. My opportunity didn't last long before this beauty went back on patrol.

I have a TC stashed away with my Super Program because I mostly shoot transparency film. What you shoot is what you get. With my K-3, I've never bothered with a TC. With few exceptions I do exactly what I did when I had a wet darkroom - I work with a RAW image crop. Unless I am doing extreme cropping or print enlargement, the K-3 has plenty enough resolution to toss away some pixels. At any rate, the result is never any worse than the loss of IQ from TC use.

The company went bankrupt, but if you can find somebody selling their hardware, the software is still downloadable - TriggerTrap.

TriggerTrap runs on both Android and iOS and offers a LOT of different timelapse options in addition to shutter activation based on the phone's sensors. Basically the software sends a tone to the headphone jack. TriggerTrap is plugged into the headphone jack and converts the tone into a switch recognized by the camera's remote release port. By the way the Pentax cable is the same one used by a number of Canon cameras.

Your camera is set to Bulb and the software controls the frequency and duration of exposure. You can use two devices with TriggerTrap software where one wirelessly controls the other one connected to the camera. The one thing you don't get is a live view on your phone/tablet.

Speed Graphic- with 4 hands you can simultaneously swap film, change flash bulbs, set shutter/aperture, and focus. Use a bulb release so you can stomp on it to release the shutter.

In my opinion, the only individual who might not be able to adapt easily to current dSLR cameras is an individual missing a right hand. I say easily rather than impossible because it wouldn't be difficult to add a left side grip with a shutter release. Tripod socket mounted left-hand grips with a flash shoe on top used to be pretty common accessories. Once upon a time I had a reason to put a cable release on one and use my right hand to focus.

With today's electrical remote release (versus the older cable releases), it would be rather simple to mount a push button and wire it to the K-3 socket. Auto-focus, and multiple auto-exposure options take care of the rest.

I use the popup flash fairly often for either fill or controller for my external flash when I am travelling light (please ignore pun) and have room for only one or all too often, no external flash. As much as I would like to automatically store location for my images, the popup is of much greater value to me.

The example below was taken pre-K-3 with a K-30, but it still illustrates the point-
My wife and I flew down to Austin, Texas to visit our daughter and son-in-law. Had I KNOWN my daughter was going to hit me up within 30 minutes of arrival for a headshot to go with her bio (she is a self-employed technical document certified translator), I would have somehow brought a couple extra pieces of equipment. There was no suitable backdrop in her home, and the sun was way too contrasty even with fill flash. I finally put her in deep shade behind her garage with enough depth to blur the background. I used my spouse as a light stand with my external flash to simulate (more controlled) sunshine. I used the popup as a controller and for fill. The result is shown below. Great? No. But more than adequate to the need.

Shooting in studio with K-3II

SDHC cards maxed out at class 10, but speeds kept rising. The manufacturers adapted the "U" suffix (UHS). The higher the U number, that faster the faster the write speed. U1 is 10mb/s, U3 is 30mb/s. Most of those other speed numbers are referring only to read speed. U3 is regarded as the minimum speed necessary to record 4K video and while that is not the goal in this thread, it certainly isn't going to hurt writing stills to the dual cards either.

How fast are those cards? I use 64gb class 10 - U3 cards in my K-3, saving RAW (DNG) to one card and highest quality JPEG to the other. I've never had to wait for a write. This includes the times I bracket shoot.

(sorry I've been too busy for this forum for a few months)

Hmmm, something not pointed out in this thread is cropping. I have a TC I use with my film kit because I shoot transparencies. Unless you digitize them (these days, printing also includes digitization), what comes out of the camera is what you get. However, the K-3 (ii) has plenty of resolution to toss some away in a digital crop unless you are making exceptionally large prints or the subject isn't sharp to begin with.

If you cannot afford a longer lens or high quality TCs, do not rule out cropping as an alternative to adding glass. As a side benefit, your bag will be lighter. I'll bet even Mr. Norm has done a fair amount of cropping in his time and still had saleable images.

We were recently at the lakeside seasonal cottage.I have so many images collected from that area and the purpose was a work bee to get it open for the summer. All I took was my K-3 mounted with the 181-35.

A pine cone fell to the deck. I picked it up, set back down and thought 'what the heck'. I zoomed to 135mm stepped back and forced the aperture wide. I took one shot with auto focus.

Once more stop would have been better in my opinion, but none the less, this is my new PC desktop background.

Pentax K3 Stock Lens Problem

Personally, I'd look at the K-3ii versus the KP rather than the K-70. And my decision would be based on what functions I regularly used with my K-3.

Quick depth of field preview is important to me, but when ALL I can take is a body and one lens, I find I use that built-in flash for fill an awful lot. Battery size would also have some impact on my final decision.

I'm not clear what you mean by "not the same". Are you talking exposure or composition? If composition, is this using the playback button (triangle button) - by any chance have you activated the magnify feature?

Self Timer Lamp Blinks with Remote... Why?
Posted By JimJohnson
Replies: 11
Views: 1,229
The camera confirms the shutter release because success via IR remote is variable. Why?
  • The user has no good idea if the remote's battery has adequate power.

  • Other IR sources clutter the signal, sort of like trying to hear a conversation across a room during a cocktail party. The sun in particular is a HUGE source of IR white noise. The greater the IR white noise between the remote and the camera's receiver, the closer you have to be to the camera to punch a signal through it. Electronic flashes also put out a fairly strong IR pulse - really? Most current camera makers use it to wirelessly control auxiliary flash units.


The K-3 (ii) shutter is quiet in comparison to other focal plane shutter cameras and especially in noisy scenarios you may not otherwise know whether or not the shutter was released. Personally, I'd like to know whether or not the shutter tripped without having to check via the camera's playback function.

Good to hear some kind of update. My film kit is patiently waiting, and I am getting impatient.

I stopped by Precision Camera in Austin Texas a few weeks ago when I was in town and asked the lab section clerk for information. She didn't know, I should contact Kodak, and more so, didn't care. She was a Kodachrome fan. (I never cared for the exaggerated red bias and shot very few rolls of Kodachrome).

True if you are doing a 1:1 reproduction (that is, a film camera or the K-1). Not true if you are using a APS-C camera. Then you are better off with something around 70mm and likely a short extension tube at the slide duplicator end. There are some threads about this in the Forum.

Pentax Auto Bellows A with Slide Copier A - Question
Posted By JimJohnson
Replies: 25

You are going to potentially run into a couple problems.
  • First, have you made sure the bellows will mount to the K-1? While both obviously use the K-mount, on some digital Pentax cameras the pentaprism housing is too close to the lens mount to allow this bellows unit to attach. I have the bellows, I don't have a K-1.

  • Second, although the bellows says Auto Bellows A, you cannot use the 'A' setting on the lens as the contact points are not transmitted back to the camera body. And unless your lens has an aperture ring (don't think it does) you will always be shooting wide-open. Unless the film is exactly flat and parallel to the lens (near impossible), you will likely have soft focus spots. In case you didn't get the manual it says "Note: When you use a Pentax A lens, set the aperture ring at each f-number and do not set it at the "A" (Auto) position.".

  • Third, there is no auto focus.


And of course you will either want to use manual flash or green-mode stopdown metering with natural light.

My advice? Get one of the well-recognized K or KA 50mm lens, stop down to f/8 or f/11 and bounce a manual flash off a photographic white card beyond the slide duplicator. While a macro lens might be better, I have had good results with my trusty Pentax KA 50 f/1.8 (stopped down as mentioned, of course).

Good to be back, and see the topics are still mostly on filling our bellies with 'comfort food'. :)

My wife and I have moved south for the rest of the winter - probably not too far from Ruppert's (R.I.P.) stomping grounds in south-central Texas. The transition has been an adventure, but sadly no time for either photography or pleasurable time on the Internet.

K-3 irregular shots in timelapse mode

One other possibility for irregular interval shooting - are you using a fixed manual exposure or auto-exposure? If auto-exposure and the scene is getting darker, it could be the exposure length is exceeding your interval period. And yes, as previously suggested, I always use external power for anything other than very short interval shooting.

Personally, my default exposure setting is to 'overexpose' by 1/2 stop. But that doesn't mean I stay there. It is just my starting point. BigMackCam is correct that this depends on the scene and the photographer's personal style.
