K-X Zoom Issues

bedinaboxgal · 07-24-2011, 04:14 PM

Thanks JeffJS. I will simulate the shots and post the results.

I took these photos to help out. On the left, the actual photo, and on the right, the camera taking the photo. First the lens is at 210mm, second, at 70mm - I don't have the DA 50-200 either.

I thought of a way to create the opposite issue, a zoomed-in image on the LCD but normal in the viewfinder and recorded image. That could happen if you set up Quick Zoom in the Playback Display Method screen, page 203 in your manual.

K7?

What was in the viewfinder was also what was on the screen, Correct? Or did you shoot these with Live View?

bedinaboxgal · 07-25-2011, 11:36 AM

Actually what was showing in the viewfinder was zoomed in more than the actual photo taken. I was not using LIve View to take the shot. I have taken several shots that when I was looking thru the viewfinder, I thought I was getting a close shot. When I go back and look at the photo on the camera, it is nowhere near the image I would see with the viewfinder. I have had a few people comment that with that lens, I should be able to get really close. It is almost as if the lens is working but the camera is not recognizing the lens. I know this sounds crazy but I am at a loss as to how it happens.

Apologies, but a few more questions. How are you zooming? Are you physically turning the zoom on the lens, or adjusting some control on the camera? Are you using live view?

bedinaboxgal · 07-25-2011, 12:17 PM

I manually zoom the lens. I am looking through the viewfinder not using live view..

bedinaboxgal · 07-25-2011, 12:17 PM

Is there a control on the K-x that I need to be using to get the full effect of the zoom?

JeffJS · 07-25-2011, 02:07 PM

No. This still isn't making any sense. Even with a cropped viewfinder (93% vs 100%) you should still be seeing only a Little bit more on your screen than in the viewfinder. The ONLY thing I could Possibly think of here is (and it's as much of a long shot as me winning the New York Marathon) is that the AF is somehow tangled up with the zoom. Try putting your camera into Manual Focus. Set your lens at 50mm and focus on an object and take the photo. Do the same thing at 200mm. Note whether turning the focus ring is somehow zooming the lens. Again, LONG shot.

Does your 18-55 behave the same way?

No, but if you were using Live View there's a way to see a magnified view of the center of the image, that you might have confused for zoom. But you're not doing that.

I am at a loss for ideas, like I suspect most people are.

Does the image you see through the viewfinder change when you take the photo? (i.e. is it the same before and after?)

Are you using any sort of adapter or aid to look through the viewfinder?

This is one of the most mysertious threads I've read on this forum.

Due to the nature of an SLR camera, what you see (as in the framing of the scene) though the viewfinder will be what ends up as your photo only allowing for the viewfinder coverage which is close to 100%. There's no rational explaination I can think of other than "faulty memory syndrom" aka, user error.

subeeds · 07-25-2011, 04:18 PM

I've never run across this with my K-X. You've got it set on MF and not AF, and the aperture ring is permitted? (pg. 282 in the manual) Other than those 2 things, I've got no ideas.

bedinaboxgal · 07-29-2011, 06:51 AM

Thanks everyone. I expect much of the questions I have are based on my lack of knowledge. I am going to read up a bit more on this camera. I do not doubt "user error" at all!

I agree on this

, I am still not sure what issues the OP has with the camera...the only thing I can think of is the VF not covering 100%, so the OP gets a larger picture on the LCD than seen in the VF...but I'm not sure

.

Can you do the following:
Put the camera on a tripod , zoom in to an object, put your camera phone up to the eyepiece and take a picture of what is in the eyepiece.
Now click the shutter on the camera.
Show us both pictures.
This is from my K-x with my iphone up to the viewfinder, followed by the actual picture.
There is a slight difference in real estate in the view vs the photo, but not much.
Lets see how yours looks.
(This is using a Tamron 18-250 set at approx 200mm as I do not have your lens.)
