Re: Eye Candy...
Thanks Tom. Im using Canon Macro 100mm f/2.8. I like very much and yes Macro lens makes a difference when you take close up pics .

Re: Eye Candy...
Tom, the things you want to look for in a Macro lens are:
1) How close to the subject can you get (12"? 15"? 6"?)
2) How low is the lens aperature (2.8? 4.5?)
3) Quality of the glass/reviews
4) mm (100/105 very close numbers, negligible difference). You'd see a bigger difference between say a 60mm lens and a 105mm)
5) lens speed
I don't see enough of a difference between the two lenses to really make either one "technically" better than the other, so I'd look to reviews to make my decision between the two. The significant difference between them is the number of elements/groups they each have (which of course affects the lens weight).

Re: Eye Candy...
I saw one on ebay that was 300mm I figured there wouldn't be much of a difference between the 100/105 but I have seen some that are 200 and 300mm and was wondering if you get further distance with a higher mm? not so much for shooting the tank but more so shooting distance like sport events and scenery?

Hey hey hey now... This is my Eyecandy thread not a discussion forum on camera lens lol.. Just kidding but would to see the discussion move so I can keep my thread with just eye candy pics

Re: Re: Eye Candy...
a 300mm lens and a 300mm MACRO lens would be two different things. A Macro lens allows you to get close to something and take a picture of it big. A regular lens would have a greater distance to subject requirement.
A 300-400mm lens would let you zoom in on a sports event... A macro lens lets you get close to a subject. So while you could probably buy a 200mm macro lens (I know Nikon makes one), you couldn't use my 200mm lens to get a close up of a fish.

correct me if I'm wrong
if u are looking at a lens & it say's 200mm & nothing else that's a true macro right?
now if u are looking at a lens & it say's 75 to 200mm that is not a true macro right?
in other words a macro lens usually only has one # (200mm) & a regular lens has 2 (75 to 200mm)
a true 200mm macro lens would be great if u had a tank that is deep but anything in the front of the tank u would have to be far to get it in focus.
my head is spinning. ???

NO!
term ZOOM means that lens does not have a fixed focal length, but can change it in a range A to B, so you can see things under different magnification - Zoom in (magnified) Zoom - out (wide range).
MACRO means that you could physically come very close to the subject and still see it clear. Or in other words, you can FOCUS on subjects that are very very close. Usually, lenses that can focus on something that is less then 3' away are considered macro. Macro lens can be of any focal length, though longer then 200mm are rare. Macro lens can be Zoom as well, or a regular Zoom can have a portion of its focal range that is considered Macro. Think of Macro as a kind of microscope in which objects look big (Macro) because you are looking them at very very close range
. Macro lens or Macro setting on a Zoom will be explicitly stated on the lens.So, focal length is what makes "magnification", zooms can have different magnifications, and only macro lenses can see things sharply enough at distances lesser then 3'.
