Anyone have any experience using this lens? Photos to show? I think this might be my next Glass purchase.

what is the advantage to a 50mm macro lens?.. why wouldn't you get a larger one, like 100mm?

Not yet, no. Money is kinda tight at the moment, and if I am gonna buy a tripod, I want it to be one of the best :) So am I holding off a bit for the time being.

I have the lens, it's nice but I will likely buy the 100mm macro as well

anyone have a comment on this? ... it is not a critique.. i am just wondering the rational

put down $20-40 on the Vivatar from WalMart. They are all pretty sturdy and work well, and won't eat out of your new tripod/lens pocket much. tripod is essential for macro

The 50mm Macro is a good lens, as if the 100mm Macro. Most people (myself included) seem to think that the 100mm is a bit better, focuses faster, etc...

You can check out ratings of it over at photozone.com and fredmiranda.com...

so basically the difference between the two would be that the 100mm provides 2x more magnification?

Hmmm... depending on how you mean, yes, in more way than one.

The 100mm compared to the 50mm lets you be twice as far away from your subject. This is helpful if trying to take a macro picture of a spookable subject, if you don't have to get so close then it might not get scared away (or bite you, hehe).

The 100mm is also a 1:1 macro lens, so the image will be lifesize on the sensor, while the 50mm is a 1:2 macro lens so the image will only be half-lifesize on the sensor.

That make any sense at all? I'm kind of tired so I may be rambling...

I rented this lens awhile back and used it for a band shoot. I had asked for the 50mm f/1.8, but the cam shop messed up and I didn't realize it until after I returned it. Those were the days before I payed attention to the aperature values in my viewfinder :-)

Anywho... some photos with that lens in low light are here

Edit: I also have the 100mm macro f/2.8, and the 50mm f/1.8 and I really like them both.

i have the lens. it's a great budget lens and can kill 2 birds with one stone - macro and a 50mm. it's half the price of the 100mm, but you can add a special converter to it later as you get more cash to bump it up to full 1:1 magnification.

Are you sure about that? With a camera like the 300D with a cropping factor of 1.6 I thought that 62.5mm focal length would equal 1:1.

I'm not familiar with the cropping factors of other DSLR's.

the 50mm is 1:2, the 100 is 1:1. It's in the specs.

I realize that - a 100mm lens equals 1:1 on a full frame sensor. My sensor however is actually 1:1.6 already meaning that a focal lenght of 62.5mm equals 100mm on my DSLR.

Unless of course - the specs specifies 100mm = 1:1 on a camera with a 1.6 cropping factor...

first of all i think you are confusing crop factor with magnification. the 1.6 is just a change in FOV, not an increase in actual magnification.

but the bottom line without hair splitting is that the 100mm gives you a larger magnification value (it too is susceptible to the 1.6 crop factor).

Anyway, I have the 50 and it takes awesome pics, just click my links above!

the subject is magnified the same amount on the rebel - the field of view is less - simulating an image that would be rendered at a focal length of 1.6x that of a full frame sensor - or 35mm film plane.

Thank you all for the help and photos!
