Questions about canon lenses and third party lenses

Don't get me wrong, I love my 100-400 but it is very large and heavy.


To clarify this one more time for me. I need to multiply all of the lens data with 1.6, right? And if I then use a converter like 1.4, can I multiply a second time for 320x1.4=448, or does it not work that way?

Yes.
 
I also have a XSI and had the 70-300 IS Canon lens. I returned it within a week of purchasing it and spent the extre $$ for the 70-200 F4 lens and have never looked back. Depending on what you are shooting you might want to go for the "IS" version, but the lens is fantastic. I also have a Tamron 28-75 1:2.8 Macro and Tokina 12-24 F4 and so far these lens have provided all that I can ever need with amazing clarity. Here is a link that shows some of the shots that I have gotten and if you want some Hi Res shots, or advice on a great place to learn/purchase gear just send me a pm.

Be prepared to spend lots of $$$$!

I have the XTi. First thing I did was purchase a 50mm canon macro lens @ f2.5. That opened up a whole new world of possibilities for me.

Then I talked myself into getting my first L series lens, the ef-24-70mm f2.8L USM lens. WHAT AN AMAZING LENS! If you ever want to shoot any events, weddings, what ever, this is a great lens. It produces some amazing pictures!

Then I wanted a better macro lens, so I checked out a few including the 180mm L series macro from canon, but looking at the price of that over the 150mm macro from Sigma, I went with the 150mm Sigma. I could have bought almost 3 of those for what the Canon cost, and it takes some pretty darn good pictures as well.

These two pictures of my blue damsel were taken with the sigma 150mm macro:

The sigma does pretty good. I'm impressed, and I like it. I bought it at adorama with that bill me later option. It works out great for me. I pay it off before they hit you up with interest.
 
You sound like me, I like to take good photos, but I am not a pro photographer and never will be.

Canon 100mm 2.8f this is your macro

Canon 28-135mm IS 3.5-5.6f (this is your walkaround/replacement for your kit lens)

Canon/Sigma Super Wide Angle (i bought the sigma, im happy with it)

Sigma 150-500mm 5-6.3f is your telephoto

Nothing is over a grand, most are in the $600-700.

The 100 macro is spot on but the rest of those aren't great. My happiest experience with my 28-135 was the day that I sold it.

For wide, the Tokina 12-24 is REALLY nice lens and it's a bargain. I can't recommend it enough.
 
man i love my 28-135, only time i don't is when i wish i had a telephoto, but i would never want to give up 28-70 or 28-100 to use the 70-200 or 100-400 (L series).

I could see owning the 70-200 but personally will never.

What did you dislike about the canon? and what dont you like about the Sigma 10-22? I read it depends on if you get good glass, but I am happy with mine.

As far as the telephoto, not everyone wants to spend 1400+ on one lens, so the cheaper, not as sharp alternatives are the only sensible option... obviously the L series canon would be preferable... or the 200-500 2.8f sigma... but im not paying 25k :c) And like already said the fixed focal length telephoto are hands down the best, but again, not everyone can afford to buy 300mm 400mm 500mm etc and so forth.


OSU domination of USC is only two weeks away beerguy. Even if we don't have our heisman runningback.
 
It's decent lens that's pretty sharp. The only thing that I really don't like is that the barrel extends when focusing. The Canon is internal so it doesn't keep changing lengths on you. When you have glass in front of you, like aquarium photography, it can be a hassle.
 
Thanks for answering. That could be a pain if I was trying to get a macro shot of something that is towards the back of the tank, which is 24" wide.
 
Just so you know, I am in the same boat as you with the XSI and 18-155is kit lens. Also have a 28-105 and 70-300 from my old film slr. I am looking for an all in one walk around lens and had it narrowed down to the Tamron 18-200 (mabe 250) IS. Then some told me about a new Canon 18-200 IS coming out next month in the $700 price point. I will sell all mine and get this one for my walk around. Then get the 100 2.8 for the macro.

Thanks for the heads up. I know it isn't out and haven't seen info out about the lens yet except that link. I will assume that the basic info about the lens is correct. Looks like a decent mid level lens that will not break the bank.
 
To also get back on the thread, I just got my canon 70-200 lens. I believe its a very good lens, since all pics were great, I just need to do more comparisons to my only other lens, the kit lens, to see the real difference.
The 100mm canon macro is also on the way ;)

Just don't pay too much attention to what you read on that site. Ken Rockwell, in many photographer's opinion, is an idiot.

Good to know! Doug, where do you recommend going for good information regarding Canon? I have been lurking on photography-on-the.net since I purchased my camera.
 
now I am really jeolous of you people who has the 70-200mm, I am saving up for a Nikon 400mm 2.8 since my wife insist on sitting way back for night concert to save on cash.
I told my wife that lense is going for $800 :D which she thinks is real waste of money already.

That's a decent Canon resource. I like Fredmiranda.com
