Thank you again Rainer!!!

I will keep in mind what you just told me...and you're right, I need the TC becuase the lens I have is a 28-90mm, so I need it to get at least a 270mm.

Thanks again for the information.

I really appreciate it.

God Bless!!!

Thank you very much Rainer!

But I still have one more question... I really don't want to bother you with my questions, but can you tell me how is the qality image for the teleconverter I have? To be honest with you, I don't see any difference on my shots(but I am not a pro, so what do I know...)so, can you tell me if it affects the quality, or just the light stops, or what...

I bought it used for $85, was that a good deal?

I will be waiting for your answer.

Thank you again.

Hi, I just got a Kenko Teleplus PRO 300 AF 3X for Canon, I am new on

photography, and I got a question.

On internet, I read that this teleconverter has 4 groups/7 elements.

Can somebody explain to me what does these 4 groups and 7 elements mean?

Please, I would like to take full advantage of the teleconverter, so please

send me a message.

Thank you.

Hi everybody, I got a question(it could sound stupid for some...but anyway)

Can anybody tell me what is cropping??

How is it made??

And...why is important to have a good image quality to do so??

If it is just cutting the picture, there is no reason of good quality. Am I

right??

I ask this because I saw a report stating that in order to crop a picture, it

is needed to have good quality...

OK Bill, thank you for the advice, it really helped, so, what I am going to do is to buy the Canon EF 70- 300mm f/4-5.6 IS USM, and later on I will save money to buy something stronger...

Thanks again!

Hi people, I am new on the photography thing, and I got a question. I would

like to get a new lens for my camera...It is a Canon EOS Rebel T2, and I saw

in internet a lens of a brand I never heard of, it is the Opteka 650- 1300mm

for canon cameras. I heard it is not a good lens, but I saw some pics taken

with that, and I don't see too much lack of quality. But I am an

amateur...maybe there is something I didn't see. Is there a way you an tell me

how the quality of this lens really is? Also I am about to buy a Canon EF 70-

300mm f/4-5.6 IS USM, but since the Opteka is extremly cheap, I would like to

have that one too; so I can have multiple choices of range... But if it has no

quality, it would be better to wait, and get a better one. Please help me on

this. If you can show me any sample pictures of the Opteka 650-1300mm, it

would be great.

Thanks!!!
