Bit of a long story but I hope you can persevere; I am after help and advice from people at a.net because I know you guys know what you are talking about and speak with unbiased views on this matter.
Some of you may, or may not have noticed I have only uploaded two new images since early October 2005. This is because I have had serious problems with my camera gear.
I have used a Canon D30 for years with a Sigma EX 100-300mm f4, no problems great quality photos all round; June 2005 I purchased a Sigma EX 24-70mm f2.8, again worked fine, great lens.
In October 2005 I purchased a used Canon 20D from a camera shop 50 miles from me, I purchased it over the phone and when I recieved the body I took it out with my lenses to see how it all worked.
My 24-70mm lens had severe focus problems, here us one example of a 100% crop, uneditied :-
the same body with another lens, I think it was Canon 24-85mm :-
I had read about the Sigma EX 24-70mm f2.8 having focus problems with the 20D so I thought I will send it to Sigma for fixing, however a morning at LGW
revealed my 100-300 was also having problems with my 20D, not focus but the images were softer than they should be and this was irratic, some worse than others.
I sent my 20D and both lenses to Sigma for testing and calibration after 3 months, yes you read that right they have managed to get the 24-70 "within acceptable levels, but not perfect" and the 100-300 is still softer than it should be. Out of interest they say my lenses work fine on their 20D body and their versions of my lenses they have work fine on my 20D!
Now, this is where your opinions and thoughts will be useful to me.
What would you do in my position? I own a D30 which my lenses both work fine on and I own a 20D which neither do. I still have a warranty on the 20D body until April 2006 by the way and both lenses are out or warranty.
The way I see it I could :-
1) Try to get a refund on the 20D and buy a new 20D where I can test my lenses in the store on a number of bodies to ensure I will get it all working as it should
2) Keep the 20D and sell the lenses, buy new lenses but test them on my 20D before I buy them
3) Get my camera checked by Canon to make sure it is working as it should (even though other lenses work fine on it) and then take it from there
4) Sell all my gear and blow the money on wine, women and song
Sorry for such a long post but I hope some of you maybe able to relieve the pressure a bit on my by giving me your thoughts
P.S Please refrain from telling me I should not have purchased third party lenses, I do realise this problem almost certainly wouldnt have occured with Canon lenses but I have two cracking lenses, both bought for a great price and I am in a really tough position so could do without being kicked when im down
