Planning my next lens.. Sooo confused.

[KmH]

Quick question, should I use any filters on this new lens? It will be delivered Friday, is there anything additional I should do to protect it? The guy also asked me about the warranty... Was $50. I get 6 months protection against mechanical defects but he offers another 18 months additional coverage.

I have found both filters for 'protection' and extended warranties to be worth far less than what they cost.

To protect the front of a lens, use a lens hood. Lens hoods help control lens flare, and establish a substantial, though no doubt incomplete, zone of protection for the front of a lens.

Protection filters add an air gap that promotes unwanted lens flare.
Inexpensive filters degrade image quality in a number of ways.
Being thin 'protection' filters are pretty easy to break.

When they do break, the sharp shards of glass are usually forceably pushed back against the very lens they were intended to 'protect' and damaging it (scratches/gouges,etc).
Of course the now shattered 'protection' filter has to be un-screwed from the front of the lens which drags those sharp shards across the lens they were intednded to 'protect'.

Do not try any of this with a 'protection' filter.
