Help Vignetting

[woods757]

Hi, 

New to the Sony A7iv and sorry if this is a stupid question. I have the Sony A7iv and I am getting very bad vingetting with some of my lens I am using. I had an A6600 before. 

The lens are the following:

E4.5-6.3/44-210 mmOss

E4/10-18mm OSS 

E1.8/50mm Oss

Even at 210mm on the first lens I have a big square vingetting all the way around the picture. I expected it maybe on some very wide angle lens but my 50mm and the 210 too? I feel like I am dong something very stupid. Please help. 

 

Thanks

The A6600 is an APS-C camera (cropped sensor) whereas the A7iv is full frame. Some lens are designed specifically for APS-C and when used on full frame will have a lot of vignetting.

Sony lenses designed for full frame are designated by the letters FE whereas those for APS-C are designated with just the letter E.

Full frame lenses can be used on APS-C cameras.

It is possible to use E lenses on Full Frame cameras, by setting the choice in your menus (Sorry, I don't have an A7iv so I can't tell you where about in the menu it is). This will get rid of the vignetting but will crop the photo by X1.5 so a 50mm lens will act as a 75mm lens. It also affects the pixels, so you might find the image quality is not as good as with the A6600.

Unfortunately, to get the best out of your A7iv, you will need to start getting full frame lenses. When I switched, I found I could off set the cost by selling and buying through a reputable dealer, such as MPB. Also, there are some very good 3rd party full frame lenses that are cheaper than Sony own brand.

Good luck

If you are saving some more money before buying FE mount glass but still want to try shooting with your existing Aps-c lenses, just enable shooting with Aps-c in the menu.  You will shoot at lower resolution but at least there is no more vignetting.  It might be best to sell your Aps-c kit and put it towards some full frame lenses.

in lightroom there's an option. optics > enable lens corrections

there are built-in corrections for each lens

Lightroom lens correction doesn't correct for hard vignetting due to sub-frame lenses used on a fullframe sensor. You have to use the crop feature for that.

What keeps amazing me is that people spend thousands of €$£ on a fullframe camera without actually understanding the differences relative to the APS-C camera they have been using for some time. What do you hope to gain from a fullframe camera if you don't understand these differences in the first place?
