Macro lense for Canon XTI

[LuckySingh]

how many of u r using macro lense and which ones...?/

[hobogato]

i dont shoot a canon, but for macro shots on corals i use a 100mm macro lense.

[LuckySingh]

is there a particular brand or any 100 mm works nice

[hobogato]

i dont know the brands that work with canon since i have a sony. my choices are a bit more limited than yours :)

I finally splurged and bought a dslr...Canon T3. I'm already looking at Marco lens, but I've heard extension tubes compensate. I'm a newb at this so we'll see.

[hobogato]

yep, that is another way to do it if you have a good combo lens to begin with. mine wasnt as nice, so i went with a faster macro lens

i purchased my cannon couple years ago with a very little knowledge so i just got a simple stock lense with it.....camera itself is very gud and i figure deserves a better lense.....i did quite a bit research on macro lenses and came up with cannon 100mm/2.8 usm or Sigma 150mm......
leaning more towards 100mm bc its a bit cheaper than the other..

while you are buying, make sure you have a good tripod while you are at it

Does quality (within reason) on the tripod matter? I was going to buy a cheap one online.

i doubt it....any brand should do it....i guess

[hobogato]

i have used a cheap one and a much nicer one. it doesnt make a difference in the pictures, but spending a bit more will make taking the pics more enjoyable :)

buy a lens inverter. they flip your lense so you can mount it on backwards and you get super macro lens. i'm taking about 1-4 inches(depending on lens) min focal distance

obviosly get the right thread size your your lens

[hobogato]

so you just use the lens inverter with any lens, or with a macro lens? definitely want to look into this as well as that is my complaint about using my macro lens - focal distance

I should ve act on this:bareteeth:...I picked up really cheap one from bestbuy it was on special...and now it sucks...the other ones r not less than $90...dnt know if thats a gud idea to spend so much on a tripod

[hobogato]

you might be able to find one on ebay for a reasonable price. there used to be a company called amvona that sold there. that company is gone, but other people resell their products. i got a really nice tripod from them for $45 plus shipping a few years ago.

I'm totally lost here...how can you flip your lens backwards and mount it? And even if this is possible, do you have to be within 1-4 inches from the object?

the lens inverter screws on the filter thread on the front of your lens. on the other side of this ring is a Canon EF Mount. so you mount the front of the lens to the camera. here is where it gets complicated.


your F.stop (aperture/amount of light/ feild of view) stops all the way down because the electronic camera communication contacts and lens contacts are not connecting when you have the lens on backwards. so therefore i get very little light but i get a sharper focus. this shouldnt be a problem with aquariums because this is what you want. your aquarium should be adequately lit and you want a bit more FOV fore aquarium macro's


if you want that really really shallow depth of field(very little in focus) then you need to lower your fstop. but how do you do that if your lens is on backwards and you cant control it.(because contacts are not touching...)


step 1
turn your shutter speed to about 5 seconds and set the aperture you want. like f 3.2 or 2.8...yada yada yada...
step 2
hit the shutter
step 3
while your shutter is open remove the lens from the camera


your lens has been now set to the fstop you chose. i know sounds weird but when that 5 second picture was being taken the aperture opens to what you want it to be at. when you remove it, it stays at that aperture. now you can attatch your lens backwards at whatever fstop you want.

this can really get you some great images...like these that i took last year.

oh and just to get an idea. that cactus spot was smaller than a dime..and the long spike was only about the length of a dime

[rabadanmarco]

and they were taken with my retired XTI.
