Today Olympus lent me one 17mm f1.8. From about a hundred snapshots that I took in different conditions I'm becoming convinced that the reviews and test images that I've seen represent the reality. The lens is about sharp enough in the center wide open and soft closer to the corners.

I'm not impressed with the AF speed although it is fast on the GX7. I will conduct more tests also on the E-PL5. I should note that I do have an E-M1 so I'm not using "toy cameras" out of ignorance and low budget. I'm also selling my E-M1 for a growing number of reasons in order to replace it with another GX7.

From what I see from the lens, if I buy it, I'll always have the feeling that I have some compromise of a lens compared to others I have. I'm even considering putting my 12-40 f2.8 on one camera ant the 42.5mm f1.2 or 75mm f1.8 on the other.

Today I shot with the GX7 and 12-40 under bright sunlight and again saw that on the GX7 the 12-40 is about twice as fast to focus compared to the already blistering speed on the E-M1. On the Panasonic it's just explosive fast.

I'm not convinced by the performance of the 17mm f1.8. I will try the 15mm f1.7 next and also the Voigtlander which is my last choice due to price, weight and required effort to focus. I shall try it before dismissing it.

I tested my copy of the 17mm f1.8 on an E-M5; it is pretty sharp at f1.8 everywhere except the lower left corner.  And it sharpens up with a refocus.

The attached image is a stack of full resolution crops from a resolution test chart taken at ISO 200, f1.8, 1/250 sec.  Camera on a tripod 40" from the chart.  I focused on the center, set to manual focus, and shot center, upper left, upper right, lower right, and lower left.  I then reset to auto focus and moved the focus location with each shot, again upper left, upper right, lower right, and lower left.  At each corner shot, the chart was located in the extreme corner.  The tilting is due to perspective shift.

As you can see, the lower left is not in focus, but it sharpens up when focus is taken at the lower left corner.  The loss of detail is slight, and clears up when the lens is stopped down.

In practice, I never notice this because that area is usually at a different distance and out of focus anyway.  When I get time, I'll run a full test with aperture sweep to see whether it sharpens up. Just to know what I need to do if I want full image sharpness.

I agree that now that I've stumbled upon wanting a good 35mm equiv. lens I see the hole. All my other lenses are spectacular. The 17mm f1.8 just isn't and makes my shots look like they are coming from a P&S camera. This is embarrassing for me. I shoot alongside with people with 5D mk IIIs and I like to hold no punches.

Unless you post examples of this I think that "makes my shots look like they are coming from a P&S camera" is more than a bit hyperbolic. Also, if you want to "hold no punches" then just get a 5D MkIII. Expecting m43 to get anywhere close to FF performance as far as DoF and high ISO is just unrealistic. If you're getting the "P&S" look from base ISO then I'm calling bull.

It really all comes down to the photographer, because if you're any good the bride won't care if your 17/1.8 isn't pin sharp across the frame at the pixel level. Joseph Victor Stephanchik is a very successful wedding photographer who uses the 17/1.8. You'd do well to study his work and see what happens when you concentrate on your craft rather than the gear.

I always find it a little amusing when amateurs turn their noses up at gear that top pros use without issue for their bread and butter work. That, to me, should be far more "embarrassing".

Thank you for your comment. I'll check out the links.

You make a valid point regardless of that you are calling me an amateur. I'm reminded that I have no need to convince anyone except my clients.

you did the right thing

The only real way to know is to try a piece of kit for yourself. I applaud you for finding a way to test the lens rather than just rely on hearsay and conjecture here.

Keep on shooting!

Thanks! I would avoid f2.8 lenses because I already have some of the best and also because f2.8 doesn't provide shallow enough DoF with short lenses. If There was a 17mm f1.2 lens and it was good, I'd buy it.

I haven't read through the whole thread, but it seems like you have eliminated all the options for m4/3 since none are good enough for you. I think you are in the process of convincing yourself to switch to Fuji, Sony, Leica, Canon, Nikon, or some other option. It seems like it is the only solution. Expensive to switch, but in order to get a fast 35mm equivalent that meets your requirements it seems the way to go.

You're making a valid point. So far I see no better system than m43 for my needs.

- Fuji is slow to focus, has few lenses that also are bigger

- Sony's lenses are even larger and there are too few worthwhile

- Leica - pff, with those prices and only MF - not going to happen anytime soon

- Canon (mirrorless) - they are nowhere near as good in IQ and lens options

- Nikon (mirrorless) - same as Canon

- Samsung - haven't checked them out yet.

Still - I'm staying with m43 and I'm trying to pick the best possible lenses that match what I'm trying to do. Most likely I'm going to buy the 17mm f1.8. Obviously we managed to go through all other alternatives.

Thank you all! I'll write soon when I make the purchase.

After reading some of the more recent discussion here I think I was right.   You will need to switch to another system to get what you want.

Re: What fast 35mm eqiv. lens would you recommend for m43?

Considering you have the E-M1, I would put the Voigtlander 17.5mm at the top of your list. This was the number one 35mm focal length I was interested in for a prime lens on my two camera bodies. I looked at the other options, but after reading the reviews and assorted commented by owners I just didn't get that comfortable feeling about them. The Voigtlander had always been intriguing from the first photos I saw by other owners so I knew that someday I would want to own and use one myself. For me the 17.5mm Voigtlander practically lives on my E-M1 since it is just about (IMO) the perfect focal for everyday photography, and when the 17.5mm isn't there one of my other two Voigtlander's is usually mounted there. With the focus peaking and the image stabilization of the E-M1 it is a perfect combination of camera and lens. Give it a try by renting one and I am sure you won't be disappointed. Right now it is one of my most favorite lenses. Yes, it is a big lens and also manual, but you quickly realize an exceptionally well built lens. The trade-offs I feel support owning and using it, and I seriously doubt you would be disappointed.  I sure haven't.

Thanks, Dale. I will ask for it in the store to test it.

wow - here the X100 costs just over twice the 15mm F1.7 lens. So the X100 gives more than twice the performance as the EM1 or GX7 with the 15mm F1.7 lens?

Must be truly amazing.

Here, and elsewhere as far as I know, the X100 I bought, not the X100S, is less expensive than the 15mm f/1.7.
In the first place, aside from an excellent lens it includes a camera, double viewfinder etc.
In the second place, I never heard before that twice the price means twice the quality. It is more, I think, a matter of diminishing returns.
But we re digressing. Yes, I'm very happy with my X100, thank you for asking. Excellent lens, good sensor, much more compact than my GX7 and EM1 with the 15mm lens.

Re: It seems I was right

Today I quickly tried the Voigtlander 17.5mm f0.95 and the Panasonic/Leica 15mm f1.7.

1. The Voigtnlander

- very heavy, but feeling as sturdy as a piece of concrete. I switched from Nikon D3s to m43 mainly due to weight, so this is a decisive factor

- manually focusing with it is relatively fast for someone like me who has lost their muscle memory for this task. The focus peaking on the GX7 works quite reliably even when I try to shoot as if I'm in a hurry - like I often am during a wedding. Indeed, I still miss focus but with practice I can become more proficient.

- the aperture ring is so loose that I rotate it even by holding it. I sometimes found myself shooting at f2 without ever feeling that I've changed aperture. That's also because there are no steps on the ring and it rotates smoothly.

- the lens' sharpness is ok at wide open - the way I'd shoot it often.

2. The Panasonic/Leica 15mm f1.7

- it's very tiny and super light. It's all plastic and for weight's sake this is a good thing. I wish my 42.5mm f1.2 Nocticron was plastic so it wouldn't be so heavy for a m43 lens.

- the build quality is good. Everything feels tight.

- the aperture ring is tight and clicks noticeably. I like it.

- the lens, compared to the m.Zuiko 17mm f1.8, strikes me as very noticeably sharper. Viewing its images at 100% remains a pleasure. With the m.Zuiko I'm always reaching for the sharpness slider.

- AF feels significantly faster

My conclusion is that I'm going to buy the Panasonic/Leica 15mm f1.7 because it provides a good balance between low weight, excellent sharpness on par with my other great lenses, it's half the price of the Voigthlander, it provides me with the fastest AF from the three. It also is reasonably small to put it in my pocket with my E-PL5.

I'm happy that I found a worthwhile contender as a ~35mm equiv. lens.

What's left for me to decide is whether to get rid of my m.Zuiko 12mm f2 or to keep it. If I keep it I'll always be wondering whether to put it on instead of the 15mm f1.7.

This is so true. I've been trying to shoot exclusively with the 17 these past 2 months and man, I have to sharpen every image I take with this lens. Maybe my copy is just bad, but I'm very disappointed given its price point. I also had the Samyang 7.5 and the Olympus 45 and both require little to no sharpening.

Some people have talked about their stellar copy of the 17. Should I just keep trying until I find a good one?

Aside from the sharpness problem, the lens distortion is a bit disturbing. I recently had to take some group shots and the faces of the people on the edges are just stretched and deformed. Is this a problem with the software lens correction or the lens itself? I don't even know.

Do you have a coloured example? I make my pictures two toned too when I want to hide the fact that it's not sharp.

Isn't it great!

Indeed, I still miss focus but with practice I can become more proficient.

If you set the aperture @ f5.6 you can use zone focusing with the distance scale. Infinity is around 4-5 feet, so it's pretty easy to wander around, compose and shoot without needing to focus. I'll sometimes carry mine at waist level and just shoot without framing.

- the aperture ring is so loose that I rotate it even by holding it. I sometimes found myself shooting at f2 without ever feeling that I've changed aperture. That's also because there are no steps on the ring and it rotates smoothly.

The aperture ring was set to be stepless. You can change the aperture ring between stepless stepped by pushing and rotating the narrow ring in front of the aperture ring. When the aperture dot is yellow, it's stepless. White means stepped. Stepless is a big advantage for video. All the current M4/3 Voigtländer Noktons have the same feature.

I sometimes do the same with the 14/2.5 with A set @ 4.5.... (as for a Voigtlander 0.95, wish could afford one)

Consider the Pany 14mm f2,5.

A bit slower, but a lovely sharp lens.
