Sony Alpha A700

Question:
*Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras.

Does this apply to the Sony alpha A700?

iirc the A700 is a crop camera so vignetting for those reasons is unlikely.

As you can see - http://en.wikipedia.org/wiki/Vignetting - there are various reasons for vignetting.

The Sony A-700 has an APS-C sized sensor.

I thought you were going for the Canon 40d?

Marine1 has a couple Sonys. Perhaps you're confusing him with mercurial?

So basically on my Alpha A700 I will not have this issue ?

Not for the reason you mentioned. You might experience vignetting for other reasons though.

BTW, which lens is "the lens"?

 

[marine1]

Sigma 18-200

 

[bwana]

Sigma 18-200

Which flavour?

 

[marine1]

Huh?

 

[bwana]

Huh?

OS or non-OS?

The thread is about a Sony A700, what do you think?

 

[marine1]

I think it is OS....hmmm now to go and check

 

[arf9999]

Considering that the Sony has in-body stabilization, I think it's pretty unlikely that the lens is stabilized...

 

[marine1]

There are 2 as Bwana correctly stated, not sure if the one is OS though

 

[arf9999]

The one that fits Sony and Pentax isn't OS.

Edit: How much is the lens? Are you comparing it to the Tamron/Sony 18-250 or 18-200?

Ah - good point.

I couldn't find a Sony specific review (I didn't try very hard, I just got back from the pub and am too plastered) but the photozone review of the Canon one (1.6x crop factor. I think the Sony is 1.5x, so for the same lens vignetting should be *slightly* more) shows that there is some vignetting.

To be serious, there isn't a lens that doesn't have some level of vignetting. Even the best ones have a little (even FF lenses on a crop body). Nothing to break your head over. Aperture (and I'm sure Lightroom/DDP/CaptureOne/NX) have vignetting control that works pretty well. And even without that, with most lenses that that have reasonable levels of vignetting, i.e. 0.5 EV - 1.0 EV, it's not going to cause much of an issue.

MV's plugins, which I mentioned in the HDR thread, also has a Vignetting Corrector plugin which works Ok.
