    hdew cameras

    I recently bought a 1.4x TC mk III and a EX 600 RT flash from them. It took around a week to arrive, but their pricing was amazing. I saved around 45% over Warehouse Express pricing.

    Sigma 120-300mm F2.8 EX DG OS APO HSM

    Yep and it's a nice half way house. Especially now that there are good condition used copies of both the 120-300 and 300 LIS available. It make the upgrade more accesible and buying a S/H 120-300 isn't going to loose much if one chooses to resale.

    Sigma 120-300mm F2.8 EX DG OS APO HSM

    I would agree with the original review posted here. It's focal length at minimum focus distance is around 240mm, there's no question about that. At infinity, I think it's close to 285mm, which is reasonably for a zoom. It's a great lens, price and its performance is truely extraordinary at this...

    Sigma 120-300mm F2.8 EX DG OS APO HSM

    Yes it is. But consider secondhand if price is problem, they crop up every now and then. The AF speed is fast but not as fast as the current top Canon L lenses are. My 70-200 f2.8 L IS II is quicker to AF lock and track than my Sigma 120-300. That said, the Siggi isn't slow at all. It's just...

    Gitzo tripod fell apart and broke my lens!!!

    Last week, I was on a bird workshop and one of the other photographers had one of the new Gitzo 4 series tripods. There seems to be a new clamp device which can be tightened without the use of tools. It looks a pretty sturdy device and clamps well. The over all feel of the new tripods is that...

    http://farm8.staticflickr.com/7225/7378763282_ea0843166c.jpg Can anyone help me identify this bird please? I photographed it a few days ago on the island of Saltee off the coast of Ireland Thanks!

    Gitzo tripod fell apart and broke my lens!!!

    What astounds me is the way an expensive brand is so disloyal and unsupportive to it's customers. Maybe a court case or two are needed for Gitzo to wake up and stand by their product. It's unreasonable in my mind that such an expensive product A) doesn't like salt water and B) falls apart when...

    Anyone used Big Norman?

    I just bought a Canon 600 EX RT from them, £425 which is an outstanding price. The unit took a week to arrive and works fine...the only problem is that the manual in in Japanese

    Canon Teleconverter III - worth the money?

    There's another consideration with all teleconverters, the AF speed and accuracy is generally reduced when compared to the native lens. If I'm trying to capture a bird in take off or a bird in flight, then using a cropping method will offer greater AF capacity over a teleconverter option. The...

    Canon Teleconverter III - worth the money?

    The main benefits of the mkIII over the mkII is that the mkIII has newer coatings and is less dust and finger print prone...whihc easily happens when juggling lens caps and teleconverters. It's also built a bit better too. IQ wise, there's a small marginal improvement over the MKII but nothing...

    Bag suggestions for a 400L

    Any suggestions for carrying a 400mm f2.8 IS L about? I'm packing a pair of camera bodies, 16-35IIL, a 24-70L and a 70-200/2.8L I'll meed to be able to carry this load for about 1/2hr over fairly rough terrain, so it needs to be well padded.

    Sigma 100-300mm f/4

    I had a dissapointing copy of this lens on a Canon mount. Wide open it was fine, but mine was a bit softer at 300mm and far from stellar. With a 1.4x TC it was even softer and so i decided to sell it and get a 400mm f5.6L instead. I'm pretty sure my copy was a poor copy because I've seen some...

    Siggy 120-300mm f/2.8 OS...

    I think he pretty much sums this lens up very well. I'm probably picking up my copy of this lens up later today and I'm looking forwards to using it as my general wild life / birding lens. If I need something longer and more exotic, I'll hire a 600L. I'll find out shortly how well this performs...
