Love it. My shoot didnt go to plan the other day, predictably ended up in the pub instead.
Will try and get something done. Makes me think im going to need something longer than 70mm though!
70mm would be great for pets or tame birds, not so hot on wild ones though. something in the range 70/75 to 200/300 zoom should be reasonably cheap.
If thats still not enough then you could go for an x2 converter but, while it will double the focal length of a lens, it will also lower quality and the light getting to the sensor. This tactic wont work on some lens/camera combinations so check before you buy.
Tamron 70-300mm f4-5.6 Di LD Macro Lens is relatively cheap and very reasonable for its price.
If this isnt enough and you dont have £1,000s to spend consider either a mirror lens or an older prime, but avoid very cheap unknown name mirror lenses unless you can try it and understand the issues. The issue with mirror lenses is that they are SIMPLE, expect only manual focal control with no f/ alteration possible. Older primes will be manual only and will probably need an adaptor.
Get a good one and it will do as a short range astronomical lens, especially for moon pics.
Using a spotting scope or telescope with adaptor is also possible, but in this case its probably adviseable to only use in bright sun.
