Hi, i am looking to purchase a new lens for my k30 and wondered if anyone knew if the Pentax 55-300 was worth the additional cash over the Tamron or Sigma versions? Also any ideas on where to get the best deal? i have seen Jessops online are doing the Pentax for around £239 at the moment.

Thanks,
Ben

Cheers Andrew,

i was seeing that Jessops have a new one for £239 at the moment but cant seem to find another as cheap anywhere. I like the Quote....as long as it is decent stuff and not gut rott!

Just thought would say hi, new to DSLR and Pentax but found the K30 with the 18-55 lens a good start that is more than keeping me busy with all the functions. I am thinking of getting at bigger lens along the lines of the Pentax 55-300mm ed f4-5.8 but wondered if anyone considers it worth the extra £100 over a Tamron or Sigma equivilant? most of my photography is done at sea (work) and the extra lens would come in hand for getting some closer pictures of ships and fishing boats.
