Is this lens flare?

[Brian M.]

Hi, my first post here. I have been shooting an Electro GSN for a while. The first few rolls were superb. In the last batch I started seeing these foggy patches that always appear in top of the picture. I asked this question elsewhere whether this is lens flare or light leak. Didn't get any consensus on that. I really haven't seen any patterns to it. I have shot directly into the sun and didn't get this effect. I have shot under cloudy sky and did get it. The camera needs repairs right now and if this is in fact flare that cannot be fixed I have to think twice before spending money on it.

I don't think so, but let's listen to the experts... (I mean I can't imagine the reason...)

Cheers,

It looks more like a light leak to me. The line at the bottom left seems too straight to be from flare.

There's also something going on in the bottom left of the image. But guess is light leaks on the back cover.

Brian M, I had 2 lens with similar problem as yours. Usually an interesting patch at a specific location and usually out doors:

a. See this thread

b. More recently, I got a Sun Sola 90mm and it has extreme flare outdoors, the only angle where it is okay is when the sun is behing my back. (The rear glass has a small chip)

I am inclined to think that these are issues with the lens causing image quality problems.

hope I don't confuse the situation further.

The do it yourself seal kit from interslice on ebay is cheap. Even has detailed instructions for the yashica cameras. Looks like a light eak to me especially that vertical line on the left side of frame. Do that then check it out!

Try using a lens hood, 55mm.

I am more curious about that white cloud on top right. Hadn't even noticed the bar on left.

Check your light seals first, the pictures look a lot like the ones I was getting from my CC when the seals were bad. I've had plenty of lenses with flare issues, but none really looked like the example in your pic.

Shouldn't weak light leaks manifest themselves as red areas? If stray light from front hits emulsion, probably that would result in overexposed areas (if this isn't lens issue) ?

I had the same problem, and the cause was a a very small bend at the top of the back door (less than 0,4 mm). It was enough to allow some light to pass.
Check if both door lips (upper and lower) are flat and seat correctly in the slots of the body.

Replace the light seals; after all these are old cameras, and use a good Hood

Light leaks will appear outside the image area around the sprocket holes, lens flair should not. That said, it looks more like flair than a leaking camera. Light leaks are proportional to the time the film is sitting next to leak.
