Fuji X-T2 increases speed also: Questions about X-T2 Battery Grip & Boost Mode | FujiX-Forum.

I am not sure if that is also the case, or not, with the newer X-T3.

Using manual lenses with K-S2?

Hi Patrick,

Oh wow, now it's starting to make more sense and am glad to hear that it probably isn't the aperture block problem, since I just got this K-S2 off of Ebay this past week :)!

Thanks for the detailed explanations and discussions. It's been a long time since I was using manual lenses on Pentax, and in my memory, it just used to work correctly with my old K-r and K-x, but maybe that was just faulty memory.

Thanks again,
Jim

I got these while walking through around our backyard (both were using my Pentax 18-55).

First a new bud on one of our rhododendrons:

and just a shot down one of the somewhat worn railings on our deck:

Old school Canon glass and flashes on a K-S2?

Hi,

I just got one of the Fotodiox FD-PK adapters. I only have one Canon lens, a 50mm f/1.4.

The adapter works fine, but it is "completely" manual. It has a ring that you can turn to open up the lens so that you can focus, then you turn the ring back to stop down the lens to whatever opening your had preset.

At least for me, I then press the green button to set the exposure, and then I shoot.

I also tried it after removing the glass lens, to do some macro. Long story, but the person I bought this from must've removed it before but they put the ring in upside down, so the indents for the spanner wrench were upside down, and I had a heck of a time getting it out.

Anyway, here's a couple of pics, I think:

With the FD-PK adapter and the 50mm f/1.4:



With the lens removed (macros):







So I'll play a bit of a devil's advocate: If you already have the Canon lenses, and can get the adapter at a good price, go for it. You get both an adapter and an extension tube that'll let you use your old Canon glass for macro work.

Not a bad deal!

Also with Live view, if you press the Info button, it magnifies the Live view (probably most of you know this, but it was new to me :)!!). It makes focusing a lot easier.

Old prime lens on K-r - getting a shutter speed reading

I seem to recall that, in the old days, on cameras like the Pentaxes, you had to lift the dial up slightly before you could turn the dial. But the K-r I have doesn't have that... it just turns.

Hi,

Sorry to resurrect an older thread, but I noticed that the "Kooka" tube is available from an Aliexpress seller:

Also, that same seller has this other set:

Old prime lens on K-r - getting a shutter speed reading

You're welcome and that (the dial changing) seems to happen to me too sometimes, but you should be able to see the difference on the LCD, e.g., if you are in shutter priority, it'll let you set the shutter speed with the wheel thing, whereas if it's in aperture priority, it would let you set the aperture. Of course, that only helps if you're paying attention to the LCD screen, which oftentimes is not the case (for me, at least :)!!).

Glad it worked out for you.

Later,
Jim

Think about "Av" (aperture priority) as being the opposite of "Tv" (shutter priority) of each other (and vice-versa) i.e.:

Av = YOU set aperture first (==> it's the priority), then the camera controls the shutter speed based on its measurement of light.

Tv = YOU set the sutter speed first (again, ==> it's the priority), then the camera controls the aperture/opening based on light.

I guess earlier, you were in Tv mode, so even though you didn't realize it, you set the shutter speed and then the camera just chose the aperture for you based on light.


You'd want to pick one of the modes (Av or Tv) based on what you're trying to do.

For instance, if you want to take a pic with a lot of bokeh in the background, you will want the lens wide open and to stay wide open, so you'd use Av mode and set the lens wide open, then let the camera control the shutter speed.

On the other had, if you were shooting something with a lot of movement , you'd want the shutter speed to be fast, to freeze the motion, so you'd set the mode to Tv and set a high shutter speed, then let the camera control the aperture.

Or something like that :)!!

These were never meant to be in any competition (sorry for the hand :))... just some vacation images using a Pana P&S from a visit to Rome late last year. Both are from the Vatican Museum...
