Question: Working distance for macro work with this lens on crop sensor - does this allow me to get further away don my subject as if I had a 160 mm lens?
Document: I have a T4i crop camera. I also considered the 60mm EF-S (crop only) macro since I like to keep my equipment light, but this lens has image stabilization and a longer minimum working distance of 5.9 inches (146mm) compared to the 60mm's 3.5 inches (90mm). This is the distance between the end of the lens and the subject for 1x magnification and the extra 2.4 inches helps a lot.
That may be the best macro Canon makes in terms of optical performance, but without stabilization, I think this 100mm lens would still be my first choice. Of course, the 180mm gives you more working distance from the subject but all in all, I don't think you can go wrong with this 100mm beauty.
With IS on and and shooting at 2.8, the depth of field is extremely shallow. Any movement toward or away from the subject will result in an out-of-focus image. My 1.6 sensor certainly exacerbates the problem.
I had stayed away from macros because I always was skeptical about using them for anything but close up work, but this lens produces absolutely beautiful images no matter what the distance. The IS works wonders and I love this lens - it is now my favorite glass!
I had a Canon 100mm macro non-IS which I never had a chance to work with to my satisfaction functionally, mainly because it had to be tripod mounted to get good results.This lens breaks that barrier! The first time I used it (see included photos) the results totally blew me away. The photos I submitted were enlarged in PS and not enhanced. Damn, and all I really had to do was point and shoot to get them!
I've been in the Canon SLR system for around 5 years now and finally decided to purchase a Macro Lens. I considered going for the 60mm since I am on a crop sensor, but decided to go for the L as I have seen it is a great portrait lens as well. I have been using it for 6 months now, and it was one of my best buys.The lens has great quality and the image quality is even better. I use this lens for basically everything, focusing mainly on portraits.
Colors saturation is excellent. I do notice a small amount of CA upon pixel peeping =)The wide focus ring is great - manual focus is almost a must for macro. The lens is equally impressive as a medium telephoto on a crop body.Here is a very lucky shot of a hummingbird shot at f2.8; it was flying away and I literally had 1 second to bring my camera up, aim, and shoot before the bird was gone. Luckily it nailed the focus!
The plastic body is of excellent material so still feels pro and the focusing rings are smooth as L lenses ought to be.- Doesn't give you as much working distance- Bokeh not as creamy, but still very very good.I have not owned the non-IS version of 100mm macro so can't comment, but the IS is truly amazing, you have to try it to believe it. If you've shot macro with non-IS then try this one with IS...there is no turning back.
The Canon EF 100mm f/2.8L IS USM lens is a fantastic lens for numerous reasons. First, it is the classic 100mm macro length. While perhaps not as compact as a 60mm macro nor does it have the working distance of a 180mm macro, it offers a good compromise between the two in that it still offers a good working distance, is not too large, and with its built-in image-stabilization is actually hand-holdable for macro!
The auto focus stopped working on the 10th photo! It first stopped on about the 3rd or 4th but started working again. Now it is dead and back in the box for return.That's my review, can't say much more about it.Update, Amazon's return policy is out standing! The new lens has been great. I use it for just about anything. It is very sharp, great color. I use it on a full frame so it's a true 100 mm for me.
Answer: I think you're right... if you were at the minimum focus distance, then a subject that fills a full frame image will be only partially visible for a crop sensor. To fit the whole subject in your cropped sensor image, you would have to go further back. Electric Boogaloo is wrong, because the pixel density of an 18 MP crop sensor is higher than a 22 MP full sensor, meaning you get MORE detail, not less. A ~35 Mp full frame sensor would have the same detail as a 18 MP crop sensor.
