Canon EF-S 18-135mm f/3.5-5.6 USM

Canon EF-S 18-135mm f/3.5-5.6 USM:Canons popular super zoom lens for aps-c cameras the new USM reversion of the EFS 18 – one hundred and thirty-five millimeter s 3.5 to 5.6 is it features a couple of updates over the older STM, eversion this is canon first lens to feature their new Nano USM autofocus system, which is meant to combine the speed of USM autofocus with the efficiency and control of STM autofocus, sounds good to me and this newer lens also adds compatibility for a special motorized zoom unit available separately ,apart from that today and a change of design there seems to be no other differences from the older STM version from 2012.

A lot of people are saying that the image quality is actually the same and it’s optical specifications seem to be the same oh it costs a lot more they come in at about four hundred and thirty pounds or six hundred dollars. whereas the older STM version can be fans only about three hundred pounds or three hundred and fifty dollars .this new version seems a bit expensive then hopefully the price will come down soon the 18 to 155- millimeter focal range. Does don’t reach as far as other super zoom lenses but it is very handy we start at an average li wide-angle, zoom in seven and a half times to a hundred and thirty-five millimeter.

It’s not a huge reach especially compared to some other superzoom lenses, Tamanna’ about to release one that goes up to 400 millimeters. but it’s still a very broad zoom range and the idea is that by keeping the zoom range down a bit then better image quality should be possible.

The lenses Maxima matter of F three point five to five-point six is usable. but she won’t be getting very artistically out-of-focus backgrounds here .and shooting in dark situations could be a bit tricky. so the lens comes equipped with image stabilization. here’s some footage with it had off and now turned on. as you can see it’s really efficient holding the image nice and still for smooth handhelds video reg and sharpest til pictures. – and the headline feature is this lens’s new nano USM autofocus motor.

 It’s lightning-fast and semi-accurate the motor. is able to go back and forth throughout the entire focus range accurately in almost no time at all it’s also essentially silent just like an STM motor. it works that quickly when you’re shooting through your camera’s viewfinder. if you’re shooting an eye view or video mode with a camera equipped with canons dual pixel autofocus system. like on this Canon 70d then it’ll be a little slower but still very fast.

If you’re using a Canon camera without dual pixel autofocus and shooting a nice view mode like.I am here with my little Canon EOS m3 then the autofocus , will be a bit slower again as you can see here that’s just a limitation of the camera. you’re using the build quality of the lens is good enough .it’s made of plastic it feels okay and it’s certainly a lot bigger and heavier than a standard 18 to 55- millimeter kit lens.

It’s still quite portable it’s a little heavier than a previous STM version of the lens and the filter size for it is 67 millimeter.it’s based on a metal lens mount that doesn’t have any particular weather sealing .there’s a plastic protrusion attached to the back of the mount to stop you from mounting. it on to canons full-frame cameras. in my opinion, that’s a poor way of doing things.I think they should just offer crop mode on full-frame cameras and make them compatible but oh well.

Power zoom PZ-E1 lens review

The zoom ring on my copy of the lens didn’t work fairly smoothly even after some use which was a shame. it’s a little sticky they’re annoying there’s a lock switch to keep the lens at 18 millimeters but until the lens has been used for a few years the zoom ring is probably much too stiff for that to be needed. you can see the electronic connections unto the gear train for the motorized zoom module on the bottom the focus ring at the end of Lent feels really smooth to turn. it’s nicely done.

It’s electronically coupled to the focus motor. if you want to adjust the focus manually then either set the lens to manual focus or if you’re in autofocus mode. you’ll be able to make adjustments when half press on your camera’s shutter button the mechanism works very responsibly. this is the optional PD one power zoom adapter available separately for a hundred and thirty pounds or around a hundred and fifty US dollars .pretty expensive really but a curious device. it’s not as big or heavy as I thought it would be in fact even with four triple-a batteries inside. It’s fairly light it can be a bit fiddly to attach here .you can see that G slide it into the underside and to lock it in place it doesn’t automatically turn on you had to turn on .the camera first and you can tell it’s on by the little green LED light.

If you switch it to NZ or manual zoom mode. you can use the zoom ring as usual when you switch. it to power zoom mode today and push the switch forward or back then slowly and quite quietly. we begin to zoom in and out at your command. it only makes a quiet whirring sound when you’re zooming in the higher speed mode. as you can see from this footage when you push the switch it picks up momentum and zooms smoothly and gradually .this footage was taken in the higher speed mode.

If you stop and start the zoom again it will need to pick up a little momentum and now here it is zooming in the slower speed mode. this mode is almost silent much quieter than the faster. mode no matter how gently I pushed the switch this was a slow zoom action as I could get. I think canon could have included a couple more different speed options for example as a super gentle speed .is the zoom module worth it for your video work that’s something only you can decide certainly an expensive additional extra .something notice that when using the power zoom module your zoom range becomes limited to nineteen to a hundred and thirty-two millimeter because of the gear system.

 It will only work for the new USM aversion of the land, not the older versions and the batteries will last about 100 minutes of continuous use according to Canon. and that’s the lend the build quality is nice enough although. I’m disappointed by that slightly stiff zoom ring .some damping with the world did Canon .although perhaps too much damping would have caused strain on the power zoom module.

well let’s see about image quality .as I’ve made clear now this lens is for aps-c cameras only not full-frame .so I’ve adapted it onto my aps-c Miller s camera 24 megapixel Canon EOS m3 and I’ve turned on it in the camera corrections like most people would do at 18 millimeters and F 3.5 sharpness in the middle of the image is quite good but contrast is just okay. the corners of the image are a bit fuzzy to edit kindly add F 5 point 6 there’s a little more sharpness and contrast but stopping down to f/8 doesn’t really give any further improvement.

let’s zoom in to 50 millimeters in the middle of the image at s5 sharpness is just Okay. it’s hardly a very punchy image but this time in the corners there’s no deterioration they look fine enough. stop down to f/8 and the image there is a touch more lively as well as being a touch sharper back in the middle of the image – finally 135 millimeter. in the middle of the image at F 5.6 resolution continues to be reasonably good but not impressive .the corners are a touch soft though there’s a tiny improvement at f/8 but no further improvements at least top-down the aperture further .so overall the Landers image quality is consistently good /ok there is little cause for concern but none for celebration.

It’s sharper than others the zoom lenses I’ve tasted in the past but then again it does have a shorter zoom range so go figure and I don’t think there’s any improvement of the older STM version of the land .all right then how about distortion and vignetting at 18 the millimeter. there’s some pretty heavy barrel distortion and s 3.5 the corners look pretty dark from vignetting stop down to F 5.6 though and that vignetting is almost gone or just turn on peripheral illumination on your camera.

If he zoom in to about 24 millimeters then that distortion. is pretty much gone and 35 millimeters. it slips into pincushion distortion which remains as you zoom in to a hundred and thirty-five millimeter there’s a little vignette invisible at F 5.6 but not much and there’s even brightness once you stop down to f/8. so the Lance doesn’t struggle with a vignette in too much but its distortion is quite problematic .the lens can focus as closely as 37 centimeters or thereabouts. that’s actually really good for getting close up pictures of smaller subjects .close-up image quality on this lens is a little soft at F 5.6 and only a little bit better at f/8.So if you’re really into macro photography then a proper macro land would be a benefit to you.

How well does this lens work against bright lights at wider angles you lose a little contrast and see a few specks of slamming but overall it’s doing okay? it gets far worse as usual men though it would be worth getting a lens hood to go with this thing they are sold separately. and finally bokeh with its narrow maximum aperture, this lens can’t give you the most out of focus background but when you do get them they look fairly smooth and undistracted, occasionally complex backgrounds like foliage can get a little bit busy.

So the new Canon EF-S 18 – one hundred and thirty-five-millimeter USM is good enough. its image quality is meta impressive but it is more than good enough for casual use. and it has no particular weaknesses it’s a lens that would make video works very easy .it’s autofocus and image stabilization is second to none. if a super zoom lens is really what you want and I suppose I can recommend it. I would say that value for money is the main problem here for the extra money. Canon is asking there’s really not much improvement of the older STM model of the lens. so until the price falls a little I think you might as well just get the older lens.
