Sony 28-135mm F4 G PZ OSS Evaluation


Having a separate digital camera for photographs and movies is one in every of my era’s “uphill each methods” moments. Picture and video at the moment are so ingrained into one machine that it’s getting troublesome to recollect the times of carting alongside a separate camcorder. Whereas digital camera our bodies can now shoot video simply in addition to stills, some lenses are designed extra with video in thoughts. The Sony 28-135mm f4 G PZ OSS is a kind of lenses. It’s an E-Mount lens that may shoot video or stills, however the largest options (quiet, floating autofocus motors and the facility zoom) are designed for video.

That doesn’t imply the Sony 28-135 f4 G PZ OSS is a slouch relating to stills. Whereas there are different lenses with an as huge to telephoto zoom vary, few have a relentless aperture all through the lens. Add within the weather-sealing and beefy controls, and it’s simple to see why this lens has some attract for nonetheless photographers too. So, what occurs while you use a video-focused lens for nonetheless photographs? I spent a while with the Sony 28-135mm f4 G PZ OSS to seek out out.

The Huge Image

The Sony 28-135mm f4 G PZ OSS mixes a flexible zoom with a relentless aperture, weather-sealing, and loads of bodily controls. Whereas it’s a video-first lens, for nonetheless photographers the lens delivers photographs that aren’t too sharp and a clean slate RAW file with numerous room for play in put up.

The lens is nice, however it’s an expensive alternative for photographers who gained’t care about how non-existent the noise is from the autofocus motors. There are additionally brighter zooms on the market, although they both sacrifice vary or that fixed aperture. The lens additionally focuses extra on technical savvy than character, which could possibly be or a nasty factor relying on the way you take a look at it. 

I’m giving the Sony 28-135mm f4 G PZ OSS 4 out of 5 stars. Need one? Test them out on Amazon.

Gear Used

I used the Sony FE 28-135mm f4 G PZ OSS with the Sony a7 IV. Each the digital camera and lens have been quickly loaned to us from Sony by LensRentals.


The Sony 28-135mm f4 G PZ OSS is a cinema-focused lens that can be used for stills. The lens is ready aside by its huge zoom vary, going from huge to telephoto in a single lens whereas sustaining an f4 fixed aperture. However, it additionally makes use of curved aperture blades to provide bokeh a extra rounded look.


Instantly after opening the field, I knew the Sony 28-135mm f4 G PZ OSS was designed for video. The beefy, grippy controls are designed to progressively pull focus in video or easily alter the aperture mid-recording. The controls make the lens really feel a bit massive, however it’s additionally a 4.8x zoom, so the bigger dimension is predicted. The lens weighs 2.68 kilos, takes up a 6.4-inch slot in a digital camera bag, and takes 95mm filters on the entrance.

Near the mount, the lens has a detachable collar for tripod mounting. There’s not a lot clearance between the lens and the collar, so I most popular to work with the collar eliminated for simpler entry to all of the controls.

The primary financial institution of controls is a set of switches. Inside attain of the left hand, a big energy zoom management sits in the direction of the highest of the lens. Beneath that, a change modifications between zooming with the ring and zooming with the Energy Zoom. Beneath that’s the change for the stabilization. On the alternative aspect, the lens homes an iris lock and an aperture de-click change.

The remainder of the controls are rings. First up is the aperture, with a click on or de-click. Subsequent is the zoom, adopted by the main target ring. The main target ring is properly labeled: not typical of Sony’s nonetheless lenses. The lens switches between autofocus and guide focus with a pullback ring on the entrance of it. This pullback ring recurrently will get by chance pulled in a bag.

The entrance of the lens, which takes 95mm filters, doesn’t flip when zooming or adjusting focus. The lens ships with an oblong lens hood.

Construct High quality

The Sony FE 28-135 f4 G PZ OSS is weather-sealed. I took this lens out within the rain, mounted on the a7 IV, and didn’t expertise any points with operation. The Sony a7 IV didn’t find yourself with mud spots on the sensor, although there have been a number of specs on the within of the lens close to the mount.

This seems like a G lens. It’s properly constructed, mixing metallic and plastic to steadiness high quality and weight. Items of the lens really feel like they’re constructed with metallic, whereas the areas across the switches and rings really feel like plastic. For regular use, this lens ought to maintain up properly. Nevertheless, cosmetically, the lens could present some put on. On my rental lens, there’s a small chip within the paint the place the tripod collar attaches.


I can’t hear the autofocus motor on this lens. It makes use of floating components within the motor, which make it tremendous quiet. There’s a slight noise to the Energy Zoom, however you may focus this lens in a library or wedding ceremony ceremony to your coronary heart’s content material.

The Sony 28-135 f4 G PZ OSS had an autofocus hit fee proper the place I anticipated for this lens and the Sony a7 IV. Photographing a canine working towards the digital camera, solely about 15 % of photographs have been mushy. 

I did want, at occasions, for nearer focusing capabilities. The minimal focusing distance is about 1.3 ft. Even with the a7 IV’s high burst pace, topics coming in the direction of the digital camera did appear to exit the main target vary a bit fast. However that’s to be anticipated for a lens with such a variety.

Ease of Use

With so many massive controls, the Sony FE 28-135 f4 G PZ OSS will look a bit daunting for newbies. Then once more, any lens priced over two grand isn’t aimed toward novices anyway. 

I wanted a little bit of time to get acquainted with this lens. I needed to discover the guide focus pull management, and study that the servo change doesn’t must do with focus (like on a Canon digital camera) however prompts the zoom ring.

With all these controls, it is going to take a little bit of time to achieve for the right one with out pulling your face from the viewfinder. Fortunately, every of the rings has a barely completely different texture to them. With a while, I believe superior photographers and videographers will just like the plethora of controls.

The OSS within the title means there’s stabilization in-built. The photograph above was shot at 28mm at 1/20. With grip, I might push the shutter pace right down to 1/5 of a second at 28mm. The stabilization is first rate, however due to its weight you may’t push the stabilization fairly as a lot as you might a large prime.

Picture High quality

I wasn’t certain what to anticipate with the Sony 28-135 f4 being a video-focused lens. However I used to be pleasantly stunned. It’s sharp, however it’s not the look-at-my-pores, knock-you-over-the-head sharpness I sometimes discover from Sony’s G lenses. It’s extra of a clean slate than a personality builder. However the versatility is probably going going to be a draw for some photographers.


As an f4 lens, there are higher bokeh builders on the market. However the Sony 28-135mm isn’t missing bokeh, significantly when getting in shut and utilizing that 135mm focal size. There’s quantity of background separation utilizing the longer finish of this lens and taking pictures huge open.

Factors of sunshine are rendered into spherical bokeh balls. These factors of sunshine are barely much less spherical on the edges however don’t cat-eye as harshly as some lenses. I didn’t spot onion ringing or cleaning soap effervescent in these bokeh balls.

Colour Rendition

Setting my white steadiness within the digital camera, I didn’t really feel an awesome must edit the colours. After all, that could possibly be tied to the time of yr — mild bouncing off orange timber and an orange carpeting of leaves isn’t going to depart the inexperienced tint that’s extra widespread over the summer season. That stated, the lens didn’t appear to skew the colours away from a typical Sony. Colours have been barely extra vibrant than in actual life however general a comparatively impartial start line.

Lens Character

Sony is understood extra for technical superiority than character, and the 28-135mm solely has a minor deviation. The lens does have some slight chromatic aberration on RAW recordsdata across the backlight. There’s additionally some minor pincushion distortion at 135mm that’s corrected in JPEgs however barely noticeable in RAW recordsdata.

Flare is basically suppressed. However I might get a mushy bloom when pointing the lens straight at a lightbulb. I hoped for some cinema-style flare, however you don’t get a lot with this lens.


This lens is sharp, however not Sony sharp. For me, that’s factor. I believe this lens requires much less pores and skin smoothing than a few of their different lenses. It’s nonetheless lots sharp, even in the direction of the perimeters, however it isn’t hurt-my-eyeballs sharp. Should you picked Sony since you’re a pixel peeper, you may not like this lens in addition to others. Nonetheless, take a look at how sharp this tight crop is, catching the main points of the tiny water droplets:

Who Ought to Purchase It? 

I’ve been toying with the query of who this lens is for all through my assessment. It’s a video-first lens with options like quiet autofocus and energy zoom. That makes it a simple alternative for hybrid shooters because it doesn’t sacrifice nonetheless picture high quality. Exterior of hybrid taking pictures, what does this lens supply for stills? 

The hot button is its versatility, from 28mm to 135mm, whereas sustaining the identical aperture all through the zoom vary. There are different lenses with an analogous huge zoom vary, just like the Tamron 28-200mm f2.8-5.6. However these different lenses don’t have a relentless f4 aperture, with the Tamron having a  narrower f5.6 on the lengthy finish.

Nonetheless, it’s a $2.4k f4 lens when Sony has f2.8 zooms out there at that value. And it’s fairly heavy. I’d desire an f2.8 with out as huge of a zoom vary, and even the Tamron 28-200mm as a result of not less than the huge finish has an f2.8 for taking pictures indoors. It’s not as a result of it’s a nasty lens, however as a result of I desire the flexibility of taking pictures in low mild with an f2.8 over the flexibility of a large zoom vary.
