canon 75-300mm dslr camera lens review image
biggestper
Hi guys.
I have an XTI and have two lenses I'm looking at, hoping to buy one.
I'm looking for something with more zoom than my 75-300mm lens I have now. I found 500mm to be the next step up.
I have a Opteka 500mm f/8 Telephoto Mirror Lens for Canon EOS / Canon EF (http://www.amazon.com/exec/obidos/tg/detail/-/B000HCNMPQ/ref=ord_cart_shr/103-1628137-2139811?%5Fencoding=UTF8&m=A1P9QRDRYY6FXL&v=glance)
Which looks nice. It has nice reviews and it's quite inexpensive. A big bonus is how small it is! It doens't stick out 2 feet!
The other one in consideration is Opteka 500mm HD Lens for Canon EOS Digital Rebel XT XTi (http://stores.channeladvisor.com/47stphoto/items/item.aspx?itemid=4015373)
This only mentions 500mm, isn't there supposed to be a ###-###mm ratio? It's nice because it's a real lens, not a mirror. Downside is it's MUCH longer in length. It also as f8/-f32 with the OTHER lens only an f8. I don't know what this means.
Only $15 difference. Can I get your thoughts?
Answer
Be aware, both are bargain manual focus lenses. They will give you the extra reach you want, but will not give you the same quality as your Canon 75-300mm. If I could make a suggestion, consider a Canon teleconvertor. It will give you better quality than the Opteka lenses.
The mirror lens requires you use Aperture mode metering, FYI.
The second longer lens is not a zoom, hence no reference to any other focal length other than the 500mm. I've seen Opteka and other companies pair this with a cheap doubler for a 500-1000mm lens, but that's going from bad to worse.
Hope this is helpful.

Which camera is better, the Nikon D3100 or the Canon EOS Rebel T3?

I'm trying to decide between these two cameras with links below. I take a lot of photos at children's parties, both outdoor and indoor where there is a lot of action. Can you tell me which you think would be better for that kind of activity while producing clear and sharp images? (Also, is there one that you can make the background more blurry than the other?) I would particularly love to hear from people who have actually used these cameras. Though if you have insight based solely on the specifications listed for the cameras that would help too since I am not all that experienced with dslr cameras. Thank you :)

There's no doubt that the D3100 is one of the best entry-level SLRs available, offering very good image quality coupled with speedy operation and straightforward handling - at least for conventional eye-level use:
