I have a Canon Powershot A540 compact digital camera, and with an appropriate adapter I can use SLR type lenses with it. I'm trying to decide if this is worthwhile. I'm an amateur photographer, who only occasionally gets the chance to take pictures. I generally find my compact just fine, but now and then I want take pictures of subject very far or very close. This seems to push the compact beyond its capabilities, so adding a lens seems to be logical. Here would be my shopping list, if I were to buy from Amazon.com: [ame=http://www.amazon.com/gp/product/B0007MGFHI/?tag=cryosphere-20]Canon LA-DC52F Conversion Lens Adapter[/ame] ~ $19 [ame=http://www.amazon.com/gp/product/B0000UX67Y/?tag=cryosphere-20]Canon TCDC52A Tele Converter[/ame] ~ $88 [ame=http://www.amazon.com/gp/product/B00006HQ25/?tag=cryosphere-20]Canon WC-DC52 Wide Converter[/ame] ~ $76 I have two questions: 1. Are these accessories really worth buying? I really don't want to by an SLR instead. 2. If I buy the Canon lens adapter, can I then buy any old 52mm lens? Are then any recommended ones that are good but cheaper? Any advice would be great, thefluffanutta. PS: I live in the UK, so UK sources would be prefered.
