Canon 35-135mm  lens with a Sony NEX camera


I can't really put this lens down. Even when I got an actual Sony lens with a whole slew of additional features for a whole bunch of extra menu functions to appear in the settings it still wasn't enough to make the SEL 18-55mm the main lens, and it wasn't long before the 35-135 USM went back on.

 external Construction and design

It feels solid and durable. It's also significantly heavier than the NEX-F3 body, even more so in combination with the EOS to E-mount adapter. 

 

 

 Auto focus

I can't tell you much about this as I don't have a smart EOS lens to NEX E-mount camera body adapter. However what I can tell you is that the focusing ring has an extremely short rotational turning distance making it vastly quicker to manually focus the lens when moving between macro close up focusing and infinity. 

 Image stabalisation

This lens doesn't have electronic image stabalisation assistance. Even if it did its not really something that you can use with the NEX camera body unless you have a smart electronic EOS lens to NEX E-mount adapter. Even without image stabalisation this lens didn't really exhibit any more image blur under the exact same usage scenarios then the Sony SEL 18-55mm with OSS (optical steady shot, Sony's naming convention for image stabalisation). this was regardless of whether I was using it at 35 mm or at the furthest reaches of its 135mm optical zoom scope. Although no doubt I.S. would be much more useful on these types of lenses at 200 to 300 mm. 

Summary

image quality in a general sense is great on this lens. There wasn't much in the way of obvious visually noticeable curvature distortion in images even without the built in software lens correction active on the NEX-F3 body whilst using the canon 35-135 mm with the Sony NEX-F3 body. For taking pictures and nothing else its still my current preferred general lens of choice despite having to do it all manually. To get the most out of this lens when using it with the F3 body I generally stuck to the "M" setting on the dial as the" iMode" often wouldn't  pick the best settings for certain light conditions to select ISO 1600 or 3200 (sometimes higher) when it was perfectly possible to shoot at 200, 400 or 800 with an ever so slightly longer exposure time/slower shutter speed setting for lower image grain.  It was a little more difficult to use this lens for extreme wide panoramic picture stitching but not impossible (vastly easier with the SEL 18-55mm). Obviously it was a bit of a pain to use for video in not have the auto focusing features at my disposal. The lack of image stabailisation was hardly an issue just in how I actually use the lens when comparing it to results gleaned with the SEL 18-55 mm equipped with OSS after I'd managed to acquire one.


Some image softness under certain conditions...

In well lit conditions its difficult to notice any image softness away from the centre of the optic field of view at the appropriate shutter speed settings whilst taking more measured shots in manual mode. (...that don't require speed). I didn't even really need to stop it down. However whilst indoors during daylight conditions (with no strong source of light on a subject) and in low light a degree of softness away from the centre does begin to creep in on the NEX-F3's crop sensor when using this lens and checking the 100% crop view in pictures. It became vastly more apparent when testing it on a body of text coming from an LED back-lit computer screen at full 135mm optical zoom. The fact that its a full frame lens will no doubt compound this as crop sensors will generally fare much better for sharpness consistency with a lens specifically designed for a crop sensor as far as starter SLR kit lens optics are concerned. No doubt this 35-135mm lens would perform vastly better with a full frame sensor as found on the 6 and 5D (but still not as well as more recent canon lenses designed specifically for full frame digital cameras as well as the L lenses). Generally if working with a crop sensor camera its always best to have a crop sensor lens of some kind to get the most out of it for best optic results. In  fact I reckon an entry level canon 18-55mm kit lens (which is specifically designed for a crop sensor) and a canon EOS to E-mount adapter might actually produce better results in combo with the F3's crop sensor between the 35 and 55mm threshold.

Maybe this lens could potentially perform much better with the NEX-f3 sensor if Sony were maybe willing to calibrate the optic properties of the lens through extensive testing to then create a lens profile with the appropriate software correction for loading into NEX bios firmware. but I doubt they'd really be interested in doing that as they might be with Carl ziess and Minolta lenses. (Pentacon lenses apparently being part of the Carl Ziess historical legacy before changing their name to Carl Ziess).  

Having said that the fixed 200mm none zoom telephoto Pentacon lens was unsurprisingly crisp and sharp without any hint of image softening away from the centre (at full aperture iris dilation  under the same conditions when using it with the exact same NEX-F3 body/crop sensor and viewing the images at 100% crop.

For a sample of images produced by this lens in combination with the F3 body click this. You'll find nearly all the images there have been shot using this lens in combo with the Sony F3 body unless otherwise stated. Just so you know, the images shot of the canon 35-135 mm lens for this page have been done using the Sony SEL 18-55 mm lens.
