Sony had introduced 3 full range zoom lenses into its E-mount camera system, they are the SEL18200, SEL18200LE, and the SELP18200. The SEL18200 is the largest and heaviest among the other 2 brothers and it comes with silver chrome body; The SEL18200LE is the light edition of the SEL18200 which is smaller and lighter and come in black colour body; Both of them are using mechanical zoom ring while the SELP18200 using the power zoom which come in black colour body as well.
The lens that we are going to review today is the SEL18200LE. Due to the full focal length coverage by the SEL18200LE, this review is extremely long and please be patience and ready to go through the rest of this post to see how does this lens perform 😉 I provided a brief conclusion at the top of each testing section in case you want to get the result in a glance.

Look & Feel
The SEL18200LE is a well built piece of glass, it is solid and heavy. It well fit on my NEX-6 and the black colour on both lens and camera body match each other nicely. The focus ring is located quite close to the camera body and it is buttery smooth.
The zoom ring is larger than the focus ring and there is focal length indicator below it. It is quite stiff so that you will need some strength to rotate this mechanical zoom ring. There is a zoom lock switch for you to lock the lens at its widest angle (18 mm) to prevent the lens barrel from extending during carrying.
The lens come with a petal shape plastic hood and plastic lens cap as well.
Handheld shooting with this lens provides certain arm muscle training as the combination of the SEL18200LE and NEX-6 is heavier than most of the other E-mount lens combination. The lens extends and collapse as show below.
In overall, the center sharpness reach its peak at F 8 among the entire focal length range while the corner sharpness got perform well in the mid range (50mm – 100mm) from its wide open till F 16.
Center sharpness at 18mm is boosted at F 5.6 and maintain good details until F 11, center sharpness at other apertures are quite soft.
Corner sharpness at 18mm is pretty soft from the wide open till F 5.6, sharpness is getting better from F 8 onward.

In overall, except the 18mm and 200mm exhibit heavy vignetting at its wide open and need to stop down 2 stops to remove the vignetting, the SEL18200LE exhibits little to slight vignetting at other focal length and usually only need to stop down 1 stop to eliminate the vignetting
18mm exhibits heavy vignetting at its wide open, stop down to F 5.6 then will barely see the vignetting.
Visible vignetting at F 4.5, stopped down to F 5.6 will slightly removed the vignetting.

Ghosting and Flare
In overall, the SEL18200LE handles the flare quite well in the entire focal length range and at any aperture. Sunlight is well controlled and does not spread across the frame.
The lens largest aperture is F 3.5 at its widest open and F 6.3 at its telephoto end. The overall circular bokeh effect is beautiful but not that smooth, you can find the onion ring bokeh effect throughout the entire focal length range regardless of any aperture you use.
At the telephoto end, the SEL18200LE render a nice defocus background even its largest aperture is only F 6.3.
The SEL18200LE built-in with Sony OSS which provide excellent image stabilisation in previous few E-mount lenses test, so how does it perform in this lens? Due to the F 6.3 largest aperture from 100mm onward, the lens test had to be carrying in good light condition in order to get the safety minimum shutter speed, and only the 200mm was tested.
Interestingly, the SEL18200LE at 200mm with/without the OSS on performed closely from 1/320″ to 1/80″, the shots below 1/60″ with OSS turned on result clearer than the one without OSS turned on. Besides, the live view on the camera LCD screen and EVF did not volatile so terribly when the OSS is turned on.
Nonetheless, I was standing and holding the camera extremely steady, and it was very good light condition and the subject is perfectly still. In general, I prefer to use above 1/100″ or ideally 1/250″ when shooting with this lens at its telephoto end from 100mm to 200mm.
In my opinion, the SEL18200LE performs better at its midrange from 50mm-100mm while there is a sweet spot at 70mm where most of the optical performance result in the best here. The sharpness of this lens is good at its center but soft at corner, once you got the subject in focused properly then you will get the fair overall sharpness. The distortion can be found throughout the entire focal length but they can be fixed easily in post processing. Handheld shooting at the telephoto end is not an issue as you are able to get blur-free result at 1/100″ or slower if you got a steady hand.
When I was shooting with this lens, I really missed the large aperture of my prime lens. With the wide open of F 6.3 from 100 mm and longer, you need very good light condition or raise the ISO the prevent the shutter speed drop to 1/60″ or below (ideally to get above 1/100″).
While many other websites mentioned that this lens is soft, the issue that is more irritating me is the focusing at its telephoto end — the focusing from 100mm to 200mm is slow. The autofocusing does not respond sometimes, you have to manually rotate the focus ring (only when you are using DMF mode) so that the lens will begin to do the autofocusing.
Besides, due to shallow DoF from 100mm to 2oomm, it is advised to enlarge and examine your shots most/all of the time, especially when the light condition is not that great, because the camera focus predictor/colour focus peaking is not always nail to your intended focus area in this focal length range.
Well, the SEL18200LE provides the convenience of having one lens that cover from wide angle (27mm in 35mm equivalent) to telephoto (300mm in 35mm equivalent), with a price tag of SGD 1,199, small in size, well built lens body and fair optical performance, it is worth the consideration for the all-in-one solution for travelling. If you are always shooting in low light environment or live subject such as sport, wildlife, and etc, you may have to look for the prime lens or the constant aperture zoom lens somewhere else, this lens is not for you.
Before the end of the review, there are some sample shots from this lens as shown below.
That’s all for the review. Hope you enjoyed it and thanks for reading.
