Macro How to get good bokeh

Bokeh is typically a function of the relationship between 3 variables, aperture, Focal length, and distance to subject. To be more precise, these three variables have a large affect on depth of field which in turn will produce the out of focus region, aka bokeh. Its also important to note that these variables do not indicate the "quality" of the bokeh but more how much out of focus is the background. I.E. can you make out shapes and locations, or is it all a fine blur with no discernible features.

To get the fine blur you typically see with macro photography (this is what I am assuming you are referring to), you will typically use a macro lens at or near its shortest focusing distance (close to the subject) which will create a shallow depth of field and result in a very blurred type of bokeh. After setting your distance to subject, the depth of field can be controlled by stopping down the lens to achieve the desired result.

Keep in mind, the shorter the focal length, the closer to the subject you will need to be to obtain a 1:1 reproduction of your subject. This is one reason why many folks prefer the longer length macro lenses as they allow for a 1:1 reproduction ratio at greater distances. This is especially beneficial when photographing critters of any sort as it will help to not scare them off.

As point of note, a high shutter speed is required due to the shallow/thin depth of field when hand held. Any movement can cause the object to fall out of focus very quickly. You would be best to use a tripod to help avoid the motion blur entirely.

One of the other benefits of using the longer focal length lenses also have the added effect of increase background compression. Without getting to technical, the way the light enters the lens allows for the background to be "squished" ,if you will, causing it to appear more out of focus than the same subject framing at shorter focal lengths. To be honest this area is somewhere where I am lacking significant knowledge, so it may be best to ask professor Google for more information.

so in summary,

1. Use a macro lens or one that is "Macro or Close" focusing
2. Get close as close to your subject as you can, the closes to your lenses min focusing distance the better
3. Use your aperture to control depth of field. Note that even at small apertures the depth of field will still be very thin/shallow due to how close you are to your subject.
4. Use a longer focal length to compress the background and maintain a more comfortable distance from the subject
5. Use a high shutter speed (180th if you can)
6. Use a tripod.

If you are shooting where there is limited light, you may also what to consider a flash with a light modifier that will direct the light on the subject. Something like a snoot, or an old (but clean) cup taped to the flash will work fine.

I hope this helps. I am sure plenty of the folks here can add and or correct my advice as well. Have fun!

So I was perusing interwebs and a link to the reviews of the Hasselblad H4D-50 on Amazon popped up on one of those click bait type sites... Normally I wouldn't indulge but it seemed too funny to pass up. My gut was right, way to funny to pass up and way to funny to not share with you guys! So here's the link to amazon for the reviews (the camera is not available) they should be good for a laugh!

is this the first generation with the red front panel or the second that is weather sealed and has a white front panel?

If its the first generation, a possible cause could be that the micro switch in the external power pack plug (under the rubber cover on the side opposite the battery door) has somehow become stuck or has failed making the flash "Think" there is a an external pack there when there is not. A possible remedy is to set the flash up to charge using both the external power pack and the the internal batteries and see if the flash will charge then. to do this follow the steps below or look at page 16 in the flash manual if you have it.

1. Slide the setting switch up (switch on the right side of the flash near "test/modeling" button)
2. Press the light/format button for 2 seconds or more (sl1 or sl2 will be displayed)
3. press the mode button twice (PP1 charge using only external batteries, or PP2 charge using both external and internal batteries will be displayed)
4. Press select button to until PP2 is displayed
5. Press light/format to confirm and return to normal display.

If this doesn't work, there may be larger problems at play than the micro switch. It could be that the capacitor, or control board has failed. Both can be replaced however, its a little dangerous and not really recommended unless you are comfortable working around high voltage circuits.

Wireless control of PTTL and HSS in Pentax. Acon R930 or Cactus V6ll?

As I understand it, yes however it would only work with HSS no P-TTL.... I have not tried this so I can't speak from experience on it. However, the manual states updating the firmware to the PN version would allow the ability to use a trigger programed for pentax to communicate with a receiver programed for Nikon and fire a Nikon flash in HSS mode.


I would contact Acon through their website to verify the capability to be on the safe side.

Unfortunately, combining trigger manufacturers is not possible right now. However, I took a quick look back at the ACON manual and you can fire a Nikon flash utilizing HSS (not sure about P-ttl) with the Acon system from a Pentax camera simply by updating the firmware of the receiver to the nikon specific version. Doing this means you loose the ability to control a pentax compatible flash with that specific receiver until you re-flash the receiver with the appropriate pentax firmware version.

I have not toyed around with this as I have no need to but its a place to start if all you are looking for is HSS.

Thank you for that.

The acon 930s have the ability to use a transmitter mounted on a pentax camera and translate the signal to something that is readable by a nikon flash. you can read a little more about it here acon-photo - wonderful photography. It also offers a HSS option so long as your flahs is HSS capable. ( I have used this feature on more than one occasion.)

I do use a dual flash set up with 2 Acon 930's and 2 Pentax Af540FGZ flashes with pretty good results for portraiture. They have there quirks and the uses interface is less than intuitive. However, for the price, the capabilities they offer far exceed what else is on the market for Pentax currently.

I have created a manual (translated from the English version of the Acon manual) that i will gladly send you so you can get a better idea of what the ACONs are capable of if you would like to see it.

Look Pentax is winning awards (Big awards) with their camera Designs.

The KP = TIPA's BEST APS-C DSLR EXPERT

THe K-1 = TIPA AWARDS 2016 Best Full-Frame DSLR Expert: Pentax K-1

The K-3 was voted TIPA's 'Best DSLR Expert' 2014

So the company is winning awards and selling camera's, but no one is talking about that. I searched the threads, almost no comments on them, but when we get one about the fate of Pentax is like being in the roman coliseum watchint the gladiators battle it out....

SO here we are, discussing the doom and gloom of Pentax because some folks saw a forecast or some numbers that were dropping and are getting scared and crying out that sky is falling..... Let me tell you, I work in Oil and Gas in Texas, I have lived through this stuff, and what I can tell you is that it ain't over til its over and its one HECKUVA ride to getting there.

BP, Chevron, Exxon, Murphy, Mobile, P66 all hemorrhaging money in the subsea divisions while other divisions of the same company flourished. They lasted about 2-3 years then layoffs. Did the close up the subsea business? No and in-fact its starting back up again smaller, leaner, less top heavy, and more efficient than before. Which is most likely what will happen to Ricoh.

So why don't we remain seated, ensure our safety restraints are fastened, and keep our arms and legs inside the car at all times until the ride comes to a full and complete stop, and just quit with the DOOM and GLOOM. Go take some freaking pictures and enjoy life.....

I need a drink.

If you thought it was a larger body of water than I got my composition right! That was my aim! The picture below is of the area where I was shooting the birds yesterday. the rocks going across the water to the sign is where the cormorants were perched. This is not my picture by the way it came off of my associations web site....

The thread from DPR did shed some light on things, considering the body of water is shallow, and I am going to go out on a limb and say the temperature difference between the water and the air was around 10F, the the water was cooler than the air due to significant rainfall yesterday morning/early afternoon. So perhaps atmospheric distortion did play a role...

I was shooting handheld, I forgot to mention that... I did use spot focus and took several different photos this was the best out of them all. I am thinking that a combination of being handheld, first time using such a long lens, and not enough depth of field is what the issues are.

I tried to go to smaller aperture, however, the iso that would have been needed was getting waaaayyyy up there and the details I wanted to keep would have been lost. The lighting was not great either, lots of cloud cover in the late afternoon early evening.
