Re: Have you seen this Wifi memory card

A neat gadget perhaps ... but how difficult is it to slip out a card and put it in a card reader? I rather suspect that it would actually be quicker, given the likely download speed of these cards.

Re: Post your uncropped images!

I routinely crop my photos, and shoot them with that in mind. For one thing I don't particularly like the 3:2 ratio and much prefer 5:4 or 6:7. I didn't like the 35mm format in films days and stuck mainly to 2 1/4 square (couldn't afford the 6x7/8 cameras :( ) That's one reason I couldn't wait to ge...

Re: _Jessops 360AFD Digital Flash for my Sony camera for £39 _

Thanks very much for that tip. Just bought one for £39 - free delivery. These days I never really have the use for a flashgun, except for a macro ringflash which I do use quite a lot, but at that price It'll be handy for the occassional family gathering snapshots. I'll report back after I've tried i...

Re: Ring flash

The only time I use my ring-flash is for taking hand-held close-up/macro shots when the ambient light is too low for a high enough shutter speed (even allowing for the SSS advantage). I find it very good for that, enabling me to get sharp shots when without it I would certainly fail. I use a very ba...

Re: Lenses - Minolta Film Camera - for re-use in Digital Camera

The extra contacts are for ADI flash control - period, nothing whatsoever to do with SSS capabilities. Xi lenses also make use of those extra contact as do SSM lenses.

Re: Lenses - Minolta Film Camera - for re-use in Digital Camera

... and the SSS system will be compromised as well, but they should auto-focus and respond to camera f-stop settings ok. Greg Why do you think this? The ADI (Advanced Distance Integration) is only for flash metering. The earlier Minolta lenses with only 5 electrical contacts work perfectly with Son...

Re: Lenses - Minolta Film Camera - for re-use in Digital Camera

I've never heard of any Minolta AF lens (excluding APS Vectis) that would not work with any Sony Alpha. Some Sigmas (only a few quite old models) do have a problem as the electronics was reverse engineered and the specifications not supplied and licensed by Minolta. Even so some non-working Sigmas c...

Re: Help ! Purple spot/disc in image (Sigma 18mm 3.5)

There may some change with different apertures or when strong direct light is not entering the lens. I had a lens which sometimes but not always exhibited the problem - but it's while ago and I can't remember the details. Of course you may be able eliminate the spot in Photoshop :)

Re: Help ! Purple spot/disc in image (Sigma 18mm 3.5)

Its a problem with the rearmost lens element not having a coating designed for use with digital cameras. Light is bouncing between the sensor's anti-aliasing filter and the rear element. I don't think you can do much about it. This a problem common to many lenses which were made originally for film ...

Re: What exposure mode do you mostly shoot in?

I nearly always use P with my finger on the wheel to shift the aperture/shutter combination and my thumb on the compensation wheel. I find it the quickest way to get what I want and by standardising it becomes second nature to get the exposure without fumbling :) Occasionally I use A - particularly ...
