Sigma 8mm f/4 EX "DG" HELP!!

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7621727995

I just realized that that although the description of this item says, "DG" and also mentions the flare elimination coating, the box and manual do not say, "DG".

If you own this lens, does it look like the DG to you?

I may have been mislead  :(   I have asked the seller not to ship if it was listed wrong. We'll see.

thanks for any opinions, especially if you know for sure from experience!

The seller admits it was listed wrong. It's not the DG. He says he will refund my money.  :)

Small world, I actually sent a ebay question to that seller asking if it was really a dg lens but they did not reply.

Looking at ebay I think there are hardly any of the dg lens ever sold second hand, as you would expect for a just out product.

However all the sellers of older lens's go to the sigma website and copy and paste the 8mm fisheye details without ever noticing it is a newer model. I suspect many of the buyers never realise there is a difference either. Whether or not the new coating is more than a cosmetic change is hard to know too admitedly.

The cameta photo people were banging out old stock of the ex version new with warranty for 419 dollars for most of the last six months, though they seem out now, so I generally reckon the ex prices should be lower than that for second hand. I might be tempted around the 300 dollar mark but otherwise I agree it would be nicer to have the new version.

Looks like the cheapest is sigma4less.com at around 560 dollars for a grey market version. I imagine the prices will come down a little over the next few months as the supply chains fill up of the new model. The people selling them cheap from hong kong will then reappear too.

Anyway glad he owned up.

Hi there

Is there a big difference between the two lenses?

Cheers

I read on another site that a lens junky was saying they are just about the same. The elements and internals do not make a new lens and the coating won't make up for a hood. His summary was the DG was an EX with a new marketing campaign.

It was all about the lens coating to reduce flare. I have the EX and don't feel compelled to upgrade or side shift. The flare was never really all that bad anyway. Certainly if the price was only say $100.00 difference then yes I would most likely buy the DG version if I was buying new. But, really as far as I know it is not the be all and end all.

What flare the EX produces is pretty easily dealt with in Photoshop.

Yes, I too like the star fire affect of the lens flare... you would have to buy a separate lens filter to get that star affect.  The affect comes free with  older EX lens

By the way,  I am still checking the forum every day... reading.  Busy with Canon 5d and learning some new hardware stuff, which I will report on later when I am finished.

I personally wouldn't class the star effect as lens flare. The flare is the light spots trailing from the brightest spot (I.E the sun)

You can see an excellent example of sun flare and the EX Sigma 8mm that I chose not to edit because I liked the look of it at www.smooth360.com/panos/reddog.html The coloured light spots are 100% most definitely the lens flare. A reflective result of the bright light on the face of the lens. The orange and green effect is always the last and most dramatic of all the flaring. All would be pretty easy to clone out if need be. The alternative is to block the sun (or light) with your hand or a card in the front on image. Some tape a small card to a flexible paper clip wire and attach to the lens to position.

But in some cases you will like the effect.

Regards, Smooth

You are right.. lens flares are light reflection of the multisided aperature opening reflecting off the different internal lens optics. 

Typically a blown out light bulb or the sun would be a normal bullseye.  Sigma seems to convert that bullseye into a star affect.. which is cool.
