When Canon first introduced DO lenses (which were going to be light, very high performance, and much cheaper than fluorite long teles, yeah yeah) one of the development projects was to be a 500/2.8...

Zoom lock, perhaps.

If, as I assume from the context, you are shooting in RAW, then the choice between sRGB and AdobeRGB when you are shooting simply sets a flag in the image file to tell DPP (or whatever else reads...

Resonses from users seem to be conspicuous by their absence, so perhaps the following comments will be helpful. The MR-14EX and MT-24EX are logically identical two-head flashes (one head in...

Well spotted. It does indeed seem likely that playback/review works as on the 1DX. The "paintbrush" button obviously has two functions during playback, one of which is direct print. It is not...

Good. We make progress. You STILL haven't got your mind round it. The lens contains the electronics. THE EXTENDER (original, II) ONTAINS NO ELECTRONICS. The (Extender-enabled) lens tests what...

Believe it, it's a fact. You really don't understand, do you? Taping breaks the contact between the extra pins on the Extender and those on the lens. It makes no difference which side you...

No problem, but, as with any other Speedlite with HSS, don't heat the flash up too much by using it repeatedly over a short period.

Just for the record, here's how the original and Version II Extenders, and the Life Size Converter for the 50/2.5, report their presence to the lens. They contain NO electronic logic...

I have a GT1541T as my travel tripod; as far as I can tell it is almost identical to the GT1542T. I use it with a Gitzo G1177M mini-ball, which is a less expensive but probably less good option...

What is often ignored in discussion about the deletion of f/8 AF from the 1DX specification is that Canon bodies offering standard-precision AF at f/8 at the central AF point also offered...

Well, for starters you will presumably need not only USB but also an OS under which EOS Utility can run.

Although, come to think of it, a 60D or even perhaps 600D, would probably do the job as the body for the 24~105, but the 7D with the 100~400 is definitely the combination to use for the long end....

What others have said about macro zooms (although isn't there one genuine macro zoom for Nikon?). The EF-S 60/2.8 is a little beyond your suggested limit of £250, but well worth it if you can...

Take your 7D, 10~22, 24~105 and add a second 7D body and a 100~400. Put the 100~400 on one body and the 24~105 on the other, and keep the 10~22 handy for landscape shots. The whole lot will go into...

Arc Form Drive, not micromotor --

Nearly right

As kb2zuz points out, in-camera correction applies only to JPEGS, but this does include the JPEG embedded in the RAW file. Only peripheral illumination correction is currently applied in-camera...

Using a non-macro lens for close-up/macro work is a clumsy business, with either extension tubes or close-up lenses, and if you are doing any significant amount of close-up/macro work then a proper...

I used FL lenses with a Pellix and FTQL before moving on to an F-1 and FD lenses. Some FD lenses were essentially re-mounted FL designs. I think that may be true of the 50/1.4 (later FL version)....
