mickeysimpson Posted June 7, 2020 Share Posted June 7, 2020 I want to shoot more macro photos. What does a macro lens, e.g. Canon’s EF 100mm f/2.8L Macro IS USM, give me that I can’t get with my EF 24–105mm f/4L IS USM? Link to comment Share on other sites More sharing options...
Sandy Vongries Posted June 7, 2020 Share Posted June 7, 2020 Depends on what you are trying to do. So called True Macro involves working very close to very small subjects and achieving a 1:1 (or better) reproduction ratio. I use both macro lenses and short telephotos for insects with cropping, both produce effective and dramatic close ups, but not True Macro. The macro lens, even closer, things like photos of Stamps , copying slides, numerous other tiny subject. Macro lenses are very sharp, and have a variety of applications in general photography. Question of personal style, project needs, etc. I'm sure others can contribute more input. 1 Link to comment Share on other sites More sharing options...
Ken Katz Posted June 7, 2020 Share Posted June 7, 2020 The macro can achieve focus at around 1 foot with 1:1 magnification (a 1" subject renders a 1" image on your sensor or film). Your 24-105L can focus to 1.5 feet and will provide 1:4 magnification (a 1" subject renders a .25" image on your sensor or film). The macro lens is also optimized for close focus and is sharper up close and its IS system is more effective for macro than the 24-105L. That said, for casual use, the 24-105L is perfectly fine for close up photos within its limits. Adding a close up lens (screwed in like a filter) can get you even closer with reasonably good results if you are using a good 2 element close-up lens. Don't do a lot of macro work myself since I don't like bugs, stamps, coins, or watches. 1 Link to comment Share on other sites More sharing options...
John Seaman Posted June 7, 2020 Share Posted June 7, 2020 Actually I find the ordinary 18-55 kit lens to be very good for close up work, it can focus to less that 10 inches. And the results with a close up lens added were surprisingly good, Link to comment Share on other sites More sharing options...
digitmstr Posted June 7, 2020 Share Posted June 7, 2020 well, a MACRO lens is designed specifically for that purpose, so it will always be better than a zoom with macro *focusing* ability. Whether you need to spend the money on a dedicated Macro Lens would depend on how "serious" you are about macro work..If you only do it occasionally, may not be worth it. However, the 100m also makes a good portrait and all around lens, with some caveats. 2 Link to comment Share on other sites More sharing options...
JDMvW Posted June 8, 2020 Share Posted June 8, 2020 There are lots of options, but the close-up capabilities of the 24-105mm lens are not really among them: Here's a blast from the past: Popular Photography 2004-02 1 Link to comment Share on other sites More sharing options...
SCL Posted June 8, 2020 Share Posted June 8, 2020 Honestly, if you need to ask, you probably aren't at the point where you "NEED" one. However, in summary, the various optical corrections for aberrations in normal lenses at close distances, are minimized, usually resulting in sharper images edge to edge, ability to focus closer to your subject (or at greater magnification), better color correction, less distortion, among others. A good macro lens can be relatively expensive, but there are other options, such as supplementary lenses which screw onto the front of your current lens, extension tubes, and bellows. I went for years without a macro lens, shooting small reptiles and amphibians, but when I wanted to shoot dragonflies and small spiders, I knew I had to reopen the wallet...and have never regretted it...nature provides such a variety of subjects for a macro, and they do a great job digitizing my old slides and negatives. 1 Link to comment Share on other sites More sharing options...
paddler4 Posted June 8, 2020 Share Posted June 8, 2020 1. To get closer. If you are satisfied with the degree of magnification you can get with your current lens, you don't need a macro lens. 2. As some people have noted, macro lenses are optimized for close-focus work. If you want to experiment with macro work and don't want to invest in a macro lens, there are several alternatives, as SCL notes. Another is reversing a standard lens. 1 Link to comment Share on other sites More sharing options...
ben_hutcherson Posted June 8, 2020 Share Posted June 8, 2020 Back when I was still shooting EOS, the only decent lens I bought beyond the 18-55 was a 100mm f/2.8 Macro. I had the older pre-USM version, which I still found to be excellent. When I made a wholesale system switch and REALLY invested in Nikon, my starting kit actually had an AI Micro-Nikkor 55mm f/3.5. I don't find "normal" macros particularly useful for my work(they can be workable on crop sensors) but they are often among the best lenses in the line-up. It wasn't too long before I bought a Micro-Nikkor 105mm f/2.8D. I've added a handful of others-a 105mm f/2.8 AF-S VR, which I sold after finding it inferior to the older lens for macro work(don't know if this is the case with Canon) and a 60mm f/2.8D. I do a decent amount of high magnification photography. A lot of general purpose lenses can get surprisingly close, but typically even approaching 1/2 lifesize and going beyond there, you will be happiest with a proper macro prime. What I would say to summarize this-if you're getting close enough with your current lens, you probably don't need one(at least yet). If you're hitting the focus limiter and thinking "I wish I could focus closer" a macro lens is a logical next step. Once you have one, it opens a world of possibilities that you may never have considered before, but you may not want to explore those possibilities. 1 Link to comment Share on other sites More sharing options...
mickeysimpson Posted June 9, 2020 Author Share Posted June 9, 2020 Thank you all for all of your technical and practical advice. I have learned that which I had sought. 1) The difference between a macro lens and zooms, and I assume primes as well. 2) what the camera captures, e.g. a true 1:1 image versus a smaller image such as 1:4. Finally, I have learned from all of you that I do not need that EF 100mm f2.8L Macro IS USM that I have lusted for all of these years because I do not engage in true macro photography. I thank you all, and most of all my wife thanks you as I will not be spending a lot of money for a lens I will likely use once in a blue moon. :) Stay well!

Robin Smith Posted June 10, 2020 Share Posted June 10, 2020 It's a common misconception that one needs a macro lens to take close up pictures. For many shots the closest focus of your current lens will produce a good shot. I have been shooting lots of nature shots that many assume are taken with a macro lens, but were not. Very nice close up pics can be taken using a telephoto in particular. If you need to shoot life size (1:1) then a macro lens is needed, but very many people seem to think that you need one just to take a few shots of flowers in the garden. 1 Robin Smith Link to comment Share on other sites More sharing options...
steve_gallimore1 Posted June 10, 2020 Share Posted June 10, 2020 If you do get the urge for a macro lens and money is an issue, then it wouldn't hurt to look at a nice vintage lens. Manual focus isn't a big issue for macro and macro lenses have historically been optically excellent, so a nice M42 macro shouldn't be much of a risk. 1 Link to comment Share on other sites More sharing options...

Robin Smith Posted June 11, 2020 Share Posted June 11, 2020 Agree with Steve, above. If you really need a macro, I'd consider getting a secondhand manual focusing lens. I got a Nikkor 55mm macro for about $50. It goes only to 1:2. without the extension tube. I had the 100mm Canon macro L, which is a good lens, but I sold it as I found inadequate for street shooting (AF too slow) and I wanted this for dual use. Tokina and Tamron, in particular, make great macro lenses. AF is not needed for macro. If you want AF, then there is the Canon 50 EF f3.5 (1:2 only, although there's a close up tube available) and the original 100mm EF f2.8 macro. 1 Robin Smith Link to comment Share on other sites More sharing options...

That's very interesting about the Canon 100 f2.8 macro being too slow for street use. I had looked for info regarding its use for other types of photography and that was something I had not seen in any reviews. I recall it being OK for studio use though from the reviews I read. I think that I am probably going to shy away from a macro lens for now because the closest I get to macro photography is with flowers and maybe a bee looking for pollen..

William Michael Posted June 13, 2020 Share Posted June 13, 2020 (edited) Understood that the OP stated he's not necessarily interested in a Macro Lens anymore, yet a couple of points for general consumption - (I think there's a typo previously) - The EF 50 F/2.5, I believe, is now discontinued; I reckon good second hand copies would be available. If one is considering this lens as a purchase, it is well worthwhile getting the matching Life Size Converter. In addition to its macro function, the lens itself is superb for forensic, archival recording and copying - for example for recording art works for insurance purposes. It is an exceptionally Flat Field Lens. Regarding the EF 100 F/2.8 Macro and the EF 100 F/2.8L Macro IS - I’ve found that the AF on both is comparatively slower than, for example, most other Canon Mid-telephoto/Telephoto Prime Lenses, however, both these lenses have Focus Limiters, the former a two position selection and the later a three position selection. Employing the Focus Limiters does result in a faster AF (specifically less hunting time) which can render these lenses quite suitable for other uses, such as Street, Candid Portraiture and some Sport: though it is not necessarily the “go to lens” or “must buy lens” for those genres. As a practical example, I quite like using Prime Lenses for Portraiture / Candid Portraiture / Street Portraiture: and I have an 85mm Prime and a 135mm Prime: A long time ago I chose to add the EF 100 F/2.8 Macro to that set of Mid Tele Primes. Although I use the 100mm mainly for its macro purposes, the lens does nicely double as a 100mm for some Portraiture work and I do not see any need to have a duplicate in my kit, by adding the EF100 F/2 Prime. It is simply a matter of understanding and adapting to the limitations of AF of (all?) Macro Lenses. I think it is a poor buying criterion to enforce a limit to buy only “L Series” Lenses. I think that with a full understanding of the criteria to attain the designation of L Series, it is easy to realize that there are many other lenses in the Canon stable which will provide robust build, excellent performance and excellent image quality, over a long lifetime.

Robin Smith Posted June 15, 2020 Share Posted June 15, 2020 I used the focus limiter for the 100mm macro L and still found that it was just not reliable focusser on the street. Of course, many times it did work, but often it required a few presses on the AF button to ensure focus, by which time the subject had gone. This did not inspire confidence. On continuous focus it often was too slow to follow the subject accurately. Optically it is a good lens and for its intended use it is excellent. Also great in the studio. But for fast AF on the street, well it was not a good match. The 85/1.8 or the 70-200mms are a better bet. The 100/2 is probably better too in that regard although I have not tried it. This was with the Canon 6D and 5DIV. 1 Robin Smith Link to comment Share on other sites More sharing options...

My comment in Post #22 was not disagreeing with your experience. I think we have experienced the same thing. I described, when the limiters were employed, as "specifically less hunting time". (i.e not eliminating the hunting time). I agree about the 85/1.8 and (all of) the 70 to 200 lenses being quick AF. The 100/2 appears to have snappy AF too; I have only used that lens in a camera shop, though. WW Link to comment Share on other sites More sharing options...
