Default choice of Lens hood ?

I am looking to buy a lens hood for my tele lens 75-300,i would like to know the dirrefence between a petal type hood & a hood that is completly round without the cut outs.
Is there any advantage/disadvantage as to which style/shape type i should consider buying.
Thanks very much.

The plain cylindrical (or conical) lens hoods can obstruct the view of a lens in the corners. The flower (or petal) type lens hoods have cutouts for the corners to prevent the vignetting that can occur when using cylindrical lens hoods. That situation only happens, however, at wider angles.

In any event, the best lens hood for a particular lens is the one the lens manufacturer sells with it, or for it. If you don't have the original hood for your lens, try http://keh.com or http://eBay.com.

There's also www.lenshood.com They seem to carry just about any hood you need.

That's a mistake, right?

TCav i did look on ebay uk site but a bit confused with things like 18-55.I assume a hood of 58mm diameter from a standard lens would not work correctly for a 75-300 lens as when you alfet the range or focus length you would then possibly see some of the in the photo that has been taken,i only managed to find 1 supplier who sold a tele hood for the 70-300 lens etc. but this is the cylindrical type.Hence question on here.Please advise further .

What lens are you trying to get a hood for?

A 75-300 or a 70-300?

Canon, Nikon, Sigma, Tamron, Tokina?

Any info you can provide will help identify the proper lens hood.

The lens is to fit a Sigma DG 70-300.
This Has a 58mm diameter uv filter on the end.
This lens is fitted to my Sony A200.
On ebay.co.uk the item number is 280371374475
Apart from all the other text it reads tele lens hood for dlsr & slr A-ST
70-210mm 75-300mm &80-200mm
Please have a look if you could and advise me.
Thanks

This lens hood attaches to the filter threads on the end of the lens, not the bayonet mount that the original lens hood attaches to. It is a cylindrical lens hood like the original.

Finding OEM lens hoods for third party lenses is almost impossible, so I think this is probably the best you'll be able to do.

You may be able to find an OEM hood in the used equipment sections of photography stores. (B&H,Adorama, and KEH are ones I can think of offhand to look at)
I believe your Sigma lens is not the internal focus type, so the objective lens element rotates with focus adjustments. This makes it unable to use a petal type hood, so you (and I) are stuck with the conical lens shade.
