Does it slow the focusing speed of your lens? I have heard that focusing gets slower while using the extension tube.

I really didn't notice any difference in speed of focus. It seemed to work fairly normally.

I've been using mine for a long time now and never had any focusing issues. One of my favorite lens. I was so pleased with it I also now have the 30mm f1.4

I bought one of these and it works, but not as well as I had hoped. It is quality made, but remember if you turn your lens around you lose autofocus. I saw a review done on Youtube where a photographer compared everything from different length macro lens to extension tubes to a reversing ring and the the reversing ring performed the worse. I am thinking that you aren't allowed to post links on here. But if you go to Youtube do a search for "8 Best Macro Lenses (Unbiased review)" and see what Jim Harmer had to say.

Twist the lens. It may be that it is indeed too low to get a good focus. If you twist the lens on mine, it comes into focus.

Your 50mm is not a macro lens. It is a lens with a wide aperture and shallow depth of field shot at 1.4. The extension tube allows close focusing. I actually shoot at a higher aperture to keep the image sharp. I actually love this tube. For the low cost it is a great addition to my camera bag. Hope this helps.

Extension tubes are best used with a short fixed lens they go between the camera and the lens giving greater distance from the sensor thus greater magification, they don't work well with longer lenses or telephoto lenses. You also need to have a camera that has the ability to allow you to change lenses. Macro filters work best with longer lenses and telephoto lenses as the longer lenses length intensifies their magnification its best to get fairly good macro lenses I have these and they work well but macro lenses can effect IQ hope this helps you decide

Goof product, but wrong direction... this extends your len's focal length, but you want to shoot macro or shorter focal lengths, which requires (simpler) macro tubes. Some preserve autofocus, some don't, but all work. Lighting is key. Normal flashes will do poorly on a macro shot. Consider an LED ring light, or use a (chilled) pane of glass with bounce lighting or light from behind.

"Nick Kovacs says:way too slow...I tried it and quickly purchased a 70-200 2.8"LOL, how can the 24-70mm f/2.8L be slower than the 70-200mm f/2.8L which is equally "fast"? I own both and I notice no difference between the two, other than their reach of course.

That isn't really what this will help you do. One thing each tube does is decrease the amount of light that gets to the sensor. So i'd imagine that you'd probably have trouble balancing the f/stop and shutter speeds to get a result you like with that lens. This is ok for doing macro photography where you can control the lighting a bit better, but its really just a casual users toy for occasional use.

The time from your inspiration to take the shot will vary. In low light with telephoto, the focusing time can be noticeable, but in most cases it's pretty fast. That occurs when you press the release halfway down. After that, pressing the release the rest of the way to take the shot is essentially instantaneous.

These macro tubes work best with manual lenses. You can use the macro tubes with m4/3 lenses. However, you'll have to adjust your distance in order to achieve focus (with m4/3 lenses).

I love this lens and find it focuses quickly and is super sharp in good light, but I tried it out last week after dark at my son's marching band competition (HS football stadium lighting) and even wide open I found the focus speed slowed way down and I had far fewer "keepers" than I normally get in good light with the Sigma. My Olympus 12-40 2.8 PRO and my Oly 1.8 primes focus much faster in low light than the Sigma. I shoot with an OM-D with built in IBIS, and I used a monopod.

The AF works fine, maybe not as fast is the M43 lenses but it does work. This lens has never been a speedy lens so I've used it mostly for portraits and slow street shooting. Wonderful & maybe the top lens of the 43 lenses despite the hunting issue & slower AF. I used it for a while with my E-3, E-PL2 & E-P2 but has been replaced by the M43 45mm f1.8.

Yes this lens does focus, if you have exposure issues it has nothing to do with the lens. Exposure is what you set on the camera.

None at all on my M- it is a bit slow in the focus- but when I combined it with a short loupe to act as a viewfinder it became handy. Mine works perfectly except for the focussing time. VRR

No, it's a fixed magnification. You can adjust the focus by getting closer or farther away from the object you're magnifying.

No, that's not true. The focus ring must stop at either end of the focal range. If not, the lens is faulty. My 24-70mm lens works perfectly as designed. Both the zoom and focus rings STOP at either end of their intended range. Hope my answer is helpful for you. Regards,Tam
