    I am considering this as one of two telephoto lens to add to my collection for my new OM D E-M5II. Does anyone have any experience with this lens in terms of image quality on an Olympus MF3 body? Thanks in advance for your support. Larry

    It's a very nice lens: small, light, internal zoom, very good optics. When using a E-M1/E-M10 I set the body to use the in lens stabilization rather than IBIS. because it works better. Since the E-M5II has better IBIS I would try it with both stabilization methods to see which is more effective.

    ImageUploadedByTapatalk1428371155.693230. fantastic lens. My favorite telephoto lens. I use it on E-M10. Anti-shock should be enabled with this lens, the images are much sharper with 0s anti-shock. OIS on this lens is very effective with constant stabilized live view. Fast AF, I use it for video a lot. It is the only lens I know that is truly par-focal: in C-AF it seamlessly adjusts focus as you zoom in/out (must be in good light).

    I use it with my E-M5 Mk1, even though I'm forced to use the IBIS I still get great results with it. It performs a bit better optically than the 40-150R from Olympus, has more reach, and has a much better form factor IMO.

    I've tried a few and the 45-175 (IMHO) has the best balance between size / weight / reach / image quality. It's the only one I still have.

    Thank you all, your feedback about this lens is most helpful. I like it because of the significant reach and compact form factor. I like it over the Olympus offerings as this lens does not get larger in length as you zoom in. This make is less conspicuous. Have a good day/evening. Larry

    I wanted a very compact zoom so I got the 45-175 and I have to admit I like it very much. I was worried about the feeling of electronic zoom ring but I am pleasantly surpised it is extremely fast, smooth and precise to zoom in and out, it does not extend and I even prefer it to mechanical zoom now.

    I made a fast roundup today comparing some of my lens (all set at f6.3) and here are my thoughts after some pixel peeping:

    At 45mm it is similar in sharpness/rendering to the Panasonic 14-45 but obviously it is faster at f4 vs f/5.6
    Still at 45mm it is obviously less sharp and has less contrast then the Olympus 45mm prime (which by the way outclass most of my other lens)
    At 45mm-70mm and 140mm it is sharper and faster then the Panasonic 14-140 MK2.
    At 60mm it is even sharper then the Olympus 60mm Macro. (the Oly prime is less sharp but has a better contrast and rendering)

    The 14-45 is the sharper non-pro zoom I tried and I think the 45-175 is the sharper telezoom non-pro, plus it is a pleasure to use and it is incredibly small and light. Definitely suggested.

    Some good info here - thanks all.

    Anyone use it on the EM-1? How is it in high FPS mode with c-AF?

    I just won an auction on a used E-M1, will try it this weekend. No experience at all with CAF that actually works though, so findings may be unhelpful ;-)

    Haha! Any help is good help, Wjiang - thanks. Look forward to hearing about it!

    From someone who has never used CAF successfuly before - WOW.

    I went out to my local reserve today to test out the E-M1 with 45-175mm plus 45mm f/1.8 + C-180 1.7x TC (75mm f/2.5). The target subjects were flying seagulls, swimming ducks, and ducks flapping wings. With the E-M1, I took roughly 650 shots, of which about 150 were technically sharp enough, with about 75 keepers at the end. I'm not sure that I got the full 9 FPS out of either lens combination, but it was plenty fast enough (definitely at least 5 FPS), and I almost never encountered slow downs due to the buffer being full. CAF/TR worked well for slower subjects - basically anything except flying birds, where CAF worked better.
    • A common problem is getting the initial focus lock - without this there's no hope really. Whole bursts were lost as a result of this.
    • The main problem with flying birds was getting and keeping the bird centred in the PDAF region - this is where operator skill (or lack thereof in my case) makes a huge difference. The E-M1 with its better EVF and faster burst rate helps a lot though.
    • As far as the 45-175mm goes, the main downside is lack of light - at f/5.6 with shade, it's pretty slow, and I lost many shots due to motion blur. The 45mm with 1.7x stopped down to f/2.8 did much better in this respect - I can see why the f/2.8 telezooms would do much better.
    With the erratic flying seagulls, I managed to get about 1/10. With ducks swimming full pace towards me, it was more like 1/3, and for ducks flapping wings, over 9/10. With the E-M5 (SAF of course), the only reliable targets I could manage were ducks swimming perpendicular to my FoV. With ducks swimming towards me, anything flying, or anything moving significantly (e.g. a duck flapping its wings upright in water), it was basically down to luck.

    Thanks a lot for that Wjiang. Very useful. Good to know that the lens performed adequately. I'm in a weird situation where I am probably having to sell my f2.8 zoom to raise a bit of capital, and am looking for a decent replacement, though obviously not as fast. I use the 9fps reasonably frequently with my toddler son and on the rare occasion that I go out deliberately to shoot wildlife. I think I could get away with the 45-175 for most occasions, and potentially the 50-200 SWD for faster requirements.

    Love the help this forum gives. It's ace.

    Cheers again!

    Really nice photos... Were they taken hand held or tripod?

    Hand held. I only tend to use a tripod for long exposures or macro.

    I just did some audio recordings of the 45-175 with CAF mode on the E-M1, using a static target.
    At 175mm, f/5.6, it was spot on 9 FPS until the buffer started getting full.
    Stopped down to f/8, it managed a steady 8 FPS.
