Question about Sigma APO 50-500mm F4-6.3 EX DG/HSM Lens

1 Answer

Soft focus 3 year old lens will not focus sharp at 500mm anymore. I've taken a lot of pictures with this lens with no real problems until now. I've tried it on other canon bodies with the same results. Its just a soft focus. Never been dropped. If not mounted it's in its case. Also the finish did not hold up, it started peeling off right away. I'm wondering if it can be fixed, or if its worth it.

I would say it is fixable. It could be a couple of different things. Loose optics and/or mount spacing could be the problem. Check here on Fixya to find a repair person in your area.

The lens does not focus manually or automatically.


Hi.
I have a lot of experiencie repairing Sigma lens.
In this zoom 150-500, the problem is located at the focus mechanism. This is a rear-focus lens so the focus mechanism is close to the bayonet.
It is not very hard to repair, but is better if you send to a Sigma Service Station.
Normally the mechanism is stuck due to a fall or strong punch.

Pictures not real sharp


Joyce, if your taking the pictures in a low light situation like in the house, the lens opens up wide which gives a shalow depth of field. To get a deaper depth of field use flash or take them outside, the lense will stop down to a smaller aperture and more will be in focus.

Opteka 500mm f/8 mirror lens for my DSLR and it's says no lens


You need to turn the mode dial to Manual (M). You won't be able to use the camera's built-in exposure meter at all with this lens. You can take an exposure reading with another lens to use as a starting point, then review the pictures and histograms to fine-tune the exposure.

500mm lens will not function with my Canon digital Rebel XT.


This lens will work with Canon cameras. I use one on my Canon 30D. It is a fixed F8 you can not use auto or green box because there are not any contacts on the lens to talk to the camera. Its back to the basics manual adjust shutter and ISO to the get a correct exposer. DEFINITLY NOT A POINT AND SHOOT LENS.

Focus problems.


The canon 5d was suspected to produced low sharp pictures, but it's wrong. Sharpness is a parameter on the 5D. You can tune it in the menu/image style/ then you choose your style and hit "jump". The first cursor is sharpeness. Enjoy.

DSC-S75 focusing problems...


Without seeing a photo, here are a few possibilities. 1) Shutter speed too low (camera shake). 2) Camera is focusing on something in the foreground. 3) Focus not locked, low light, low contrast scene. Items 2 and 3 can be corrected by manual focus. Set the focus to 1 click below infinity, depth of field will insure everything is in focus. For item 1 remember that the shutter speed must be 1/125 sec or faster at full zoom to avoid camera shake.
