Hey again eveyone. My last question!!! ((for now...) no but seriously last thing ill be purchasing for this month is my filter. Need to purchase it tomorrow.


Anyways the first lens we will have on our Canon 7D is
http://www.amazon.com/Canon-Standard-Medium-Telephoto-Cameras/dp/B00009XVCZ

(im new to DSLR so please bare with me:embarasse)
So if i read it right i need to find a 58mm to fit perfectly onto that lens such as:
http://cgi.ebay.com/Fader-ND-Filter...ewItemQQptZCamera_Filters?hash=item1e593307a1

Correct?

Now people say go buy 72mm Fader ND and get a ring that goes 72 - 58 or somthing. But then people say "watch out for vignetting" ect. I Definitely dont want that effect and i want to know exactly how to stay away from that.. I did it once accidently on a video camera even sadly (i think i stacked two on the dvx when i was younger)

So whats the best bet because i need to save some $$. When i purchase our wide lens im thinking somthing like a
1. canon ef 28 mm f/2.8
2.canon ef 20-35 f2.8L


Just trying to understand how the whole step up or down rings work and where vingeting happens, how to avoid it but also be nice to the walle. Need responces as quick as possible though and will be greatly appreciated.. I have to order them tomorrow.

A 58mm filter will be much cheaper than a 72mm - they get very expensive as they get bigger.

A 72mm filter with a 58mm-72mm step up ring will not cause vignetting.

28mm is not particularly wide angle on a 550D (or any x1.6 crop sensor body) - it will look similar to a 50mm lens on a normal camera.
 
All I can say is GET the Fader ND. It is the most useful accessory you can have, especially since you really can't shoot without NDs and get good exposure. Plus, buying a full set of ND seperately is far more expensive than just getting a Fader ND, and then you have all this extra stuff to carry.

As for Vignetting, I just got the 72mm Fader and use step up rings for all my lenses. I get NO vignetting on any lens except at 17mm on my Tamron 17-50. But it's very, very slight and only if shooting from f8 and up.

I also have a Tokina 11-16. I don't have a Fader for that since it's a bit larger, but I do have 2 filters stacked on top (UV at all times, and a standard ND), and I get NO vignetting even at 11mm.

So I'm assuming that if I did have a Fader ND, there would be no vignetting.

IMO, even if you get a slight vignetting, it's worth it for the Fader because you can set the exposure so perfectly and quickly. Much more so than stacking NDs.

Actually, I get more vignetting from stacking NDs than I do from using a Fader, because the Fader is thinner than 2 NDs stacked.
 
Are there any strong feelings on who you get them from? I see that light craft workshop sells themselves as "the real Fader ND", and according to their site the only eBay authorized reseller is bonifaceleung who are situated in Hong Kong. But I also see lots of other people selling Fader NDs on eBay. And for cheaper.

I have this same question.

edit: I'll just stick with the official sellers.
 
I got one from Bonifest and he's a really cool guy. Just get the Lightcraft workshop one. They're good and they've been used by a lot of people. It's dicey to take a chance and get a crappy one that's cheaper
