Re: Test Images With Vignetting

I took the A200 out today to do a couple of sample shots , turned out at its widest angle , full open , there is a small amount of vignetting that can be seen with a blue sky .

Nothing that a few seconds in Lightroom can't fix .

Stopped down a bit and it's all gone anyway and as it tends to show up more on a blue sky of a landscape where you tend to shoot stopped down anyway , not a problem .

Stopped down a bit , no vignetting .

Wide open , just a bit of vignetting .

2 seconds in lightroom and it's all clear .

And seeing as it's a nice sunset , one showing good flair control with a colourful sky .

I realise now on your test shot what's causing the vignetting .

Notice that it is very strong at the top of the frame and clear at the bottom ?

If it was lens vignetting , a deep mounted filter causing it or the wrong lens shade , then vignetting would be the same on all four corners .

The Anti Shake being faulty gives it away .

The rods that move the sensor has jammed it towards the bottom of the camera meaning the sensor's below the lenses projected  image .

Don't forget the image is inverted by the lens , so the top of the picture is at the bottom of the sensor .

It's possible the camera has been dropped to cause it .

Dropping onto a carpeted floor might not have marked the camera but could have damaged the A/S unit .

Given the current price of these cameras I'd buy another one .

Can this one not be returned as it's faulty ?

.

If it was my camera , and I was keeping it , I'd turn the camera upside down ( hotshoe down ) and strike it hard against my other hand to see it it would jolt the sensor back into position .

This wouldn't fix the A/S unit , but might ( just might ) jolt it back into position .

As the camera is , I would consider it scrap , so nothing to lose . YMMV .

Michael, thanks for your info. I have an A2 that should arrive this week. I'm crossing my fingers it is in good working condition.

The issue with the A200 vibration at startup has to do with the camera's self-diagnostic function. The AS icon on the screen is always displayed in red, even when the green ((HAND)) button is pressed. I tried shooting in 3:2 ratio but it still happened however, not as bad.

Even if the camera had an "OFF" setting in the menu for AS, this problem would still occur as it's part of the diagnostic routine. As it is I can (1) not use wide angle, (2) crop or maybe PP the image top in wide angle shots or (3) open the camera and try to find a solution. Replacement AS mechanisms were available back in the day from Sony. I haven't seen one but if I did I'm sure it would be pricey!
