Yes, pentax is fully backwards compatible with some restrictions.
Here is some data link

With some older lenses you can have exposure metering problems, mostly it underexpose the photo. Not sure if it counts for all the Pentax lenses, FA and most lenses with auto-aperture for example seems to work fully and well by my knowledge but someone else can tell you more about it.

Edit:
What told above here is true about the 1.5x crop but that's only the Angle of View that change, it will still be an 28-80mm lens but with a narrow view of that of an 42-120mm on a 35mm camera.

I've missed that one Don, I posted a patent about a new prism viewfinder a month or so ago but didn't see any other patents gone by

Once agian the standard of the pentax forum is lowered
I'm very curious what comes next....

WR = Weather Resitance????
If so I'm tempted to buy one, would be a great adventure lens if it's cheap.

They could make it work but they need to have another autofocus system, AF TTL would be problematic since you need to redirect the image to the AF sensor but it also needs to land on the sensor to record an image.

Contrast measurment would be an AF solution but you need high contrast for that.
The camera anylise the image and makes sure that high contrast area doesn't go blurry.

Active focus would also be a solution and that eye next to the shutter release migh well be that. The problem is that the camera needs to know the focus distance of the lens so the lens needs to give feedback on that.
So far as I know no Pentax lens does that but maybe the SDM lenses might give through that information.
I've heared rumors that the DA*60-250 was late because they wanted to make the lens compatible with a new feature of the K-7 but like I said that's a rumor.

Hello Faye welcome to the forum, all the way from the USA or not?
The K2000 is know here as the K-M but that doesn't matter.

For a simple solution (and if you haven't tried it) you could set the build-in flash of your camera as controller when using wireless, it only fires a very ligh flash and if you've some distance (2 or 3 meters) of the subject the flash should hardly be noticable. see page 144 of the manual.

The RF trigger probable works with a X-Sync connect it's called I believe, the AF540 has that connection but not the AF360.
Since you have a RF it might be an option to get only an adaptor for hotshoe of the flashgun, that way you should be able to fit your RF trigger.

Other option is to get a new complete system, there are RF systems for example that work on the hotshoe and not the X-Synx conection.

The difference between the Pentax F and FG is that you can still use the build-in flash of the camera with the FG, that way you've more option if needed.

You got the right link but the html code isn't placed correctly.
it should look like this, the () needs the be the square ones [].
(img)https://www.pentaxuser.com/images/gallery/2009/05/normal/Yes--that-is-Matt_12419...(/img)

ps. in the photo section you got the wrong links Beebee they need to end on .JPG that's the photo, what you have linked now is the site.
So stand on the photo right click and say copy image adress and you should get the right one.

Here you go Beebee, please try for yourself and I'll delete this one okay if you've it up okay.
Wonderfull shot BTW

Click on the photo in your gallery and click once again so that you get the large version, if you do right click on the photo you can say copy image adress or something like that.
You can then paste the adress in the comment box, it should be .jpg on the end.
Highlight the adress and click on the button image and it will set an html code around it, img end ending with /img between brackets.

ps. there is in the photo section of the forum already a topic were you can post the photos of the PU meet.

Edit: deleted Beebee's photo

You mean the DA*16-50 right?
There were in the begining some problems with quality controll of these lenses, maybe you can compare some photos with someone else with the lens to see if it's performing okay.

The build quality of the lens seem very good and it is weather sealed so that cost something too.
I bought for myself the DA*50-135 for portrait since I found it a better range for that, maybe worth buying to get the set complete

edit: added some text...

Welcome to the Malc

Judith, I totally respect your choice and I wouldn't even have posted them (almost never post family photos for other reasons) but I thought you did it after well thought of consideration. It's sad that we have come so far that we need to do that for the few that wants to do evil but we can't risk it in such uncontrollable open space as the internet.

The nursing photos is the best one but I also really liked the soft photo, it's full with love. The K-M is surely a little beast, be sure to let it out frequently and take some shots


Don, your directness & honesty is very appreciated at this side off the screen. It's stange to see that things are differend in your country while we're nieghboors but it seems we're going your way though...

in every life we have some trouble,
when you worry you make it double
don't worry, be happy
It's your fault Don that I've that song in my head now
