Sigma/Tamron lenses

[acmerchant]

Thanks for the guidance will drop the canon and go for Tamron as suggested but now I am confused between Tamron SP AF 70-300 F/4-5.6 Di VC USD and Tamron AF 18-270 F/3.5-6.3 Di II VC LD

Tamron SP AF 70-300 F/4-5.6 Di VC USD is the one to go for unless you want to cover a long range of focal lengths.

Whilst the 18-270 may seem appealing it has to cover a long zoom range and the image quality is not as good as the 70-300. I did own the 18-270 for a while but found it had very bad barrel distorion and suffered from chromatic abbertions.

I'm in the process of upgrading to a DSLR, and think the Canon 650D is the one for me.
I have an old Sigma 170-500mm lens that I used to use on my old SLR I used before I went to digital, its not been chipped though, does anyone have an idea of the approx cost of this.....it might stop me using it if its prohibitive!
I am also thinking of buying a Canon 75-300mm f/4.0-5.6 III lens is this the one being referred to in this thread as being not a good lens?? If so, how about the Canon EF-S 55-250mm f/4-5.6 IS II???

Sorry for my first ever post on here being just questions, but I want to get it as right as possible first time!!! My main interests are aviation photography, I also take pics at airshows too, plus the usual family shots!!!

Thanks in advance for your help guys

No idea about the cost of chipping the sigma.

WIth regards to lenses for the money the 55-250mm f/4-5.6 IS II is a cracking lens and is sharper than the more expensive 70-300 EF IS, as you have established the 75-300 does not have a good reputation.

Thanks Dave.....and I would have gone for the higher mm had I not discovered this forum!!!!!

If you do want to go up to 300mm then this is a good choice. But obviously more expensive.

Hi Dave/all.

I've been offered the CANON 55-250mm f/4-5.6 IS II EF-S to go with the 650D plus the EF-S/18-55 IS II/REG.

Anyone know about either of these, is this the good 55-250 lens?

Hoping to order within the next seven days!!!
