I have looked at the reviews and it looks like the trend is that Canon's are having this issue. Good luck. I ordered one for myself to use with my Nikon D40 I hope and pray it works.

You will need to find the sweet spot for straight lines (by tilting) in your composition. Sounds like your Sigma worked the same way. Fisheyes are like that :)

I had the same problem, because this model is too similar with the compatible canon model. This lens is "designed specifically for APS-C sized sensors and Sigma SA Lens Mount" as is advertised (anyway, this very important fact should be more visible than it is)

Try looking at Google images under the search "before after flash diffuser"

I will setting mine up with a dimmer pack for the first time in a couple days. What software are you using? Im running QLS on one system and Freestyler on another.

My setup is the same. However, I am using a D5100, a DX body and an FX lens. I believe this is causing the problem. Are you using an FX body?

I had that problem, the aperture problem which resulted in overexposure. Called Fujifilm, sent the camera, and it fixed and came back. I paid the shipping cost to their service center but service was quick and replacement itself was free. I had that problem with quite early lot, but I guess current lot does not have such problem or if you have then you can get the replacement service.

Don't know. But my advise is to send inquiry directly to Sigma or call them.

The light is spread onto 4x the surface. That is why autofocus is difficult. Sharpness and contrast suffer with a T/C. I have a Sigma 170/500. Results are ok if not to picky.

Your lens doesn't provide auto exposure...you need to use a higher f stop number i.e. if your f stop is set at f8, try f11 or f16. This cuts down on the amount of light going to your sensor, which is causing the overexposure.

Is the cannon macro/telephoto? That could be a factor. Im not sure. I dont have this lens yet. Though it will be my next lens once I get this return issue with the Sigma resolved.

My experience with using Canon Speedilite 270EX II... the pictures are always Overexposed. To the point where they're completely white-out.

The diffuser tosses light up AND directly at the subject. Bouncing the flash may not be practical if a location has high ceilings, dark or combination ceilings or any obstructions that hinder bounce flash.

I've noticed this as well. I wonder if it has something to do with the image stabilizer?

Hi Marc,Sorry, I have not even been able to use mine since it arrived broken, andfotodiox was unable to help me.But, have you tried extra lighting fromdifferent angles? This usually helps.

It seems bright, but at a distance of 4 to 5 feet you'll be shooting at f/ 5.6, ISO 400 And 1/30th to 1/60th of a second. Diffusion would make it almost unusable. Send me an email and I'll send you a photo.

I doubt it; there are no adjustments to the diffuser so there is not much to do except keep it as clean as possible. You might try and see if the company would honor a warranty claim but they don't seem to stand behind their product very well.
