Yes. 46mm threads, if I remember correctly.
(...and Thanks!)

Yep, 46mm. I have a Summicron-style hood on the way, and will probably get a pinch cap that I can fit inside it.

What is a "Summicron-style hood", and where did you get it?

That's how it was described on eBay...$10 from somebody in Hong Kong...a vented RF style hood that is angled inward. I dunno if this is what the traditional Summicron hood is really like!

By the way, a few more new shots from this lens, from over this weekend.



The Contax G hoods work well on the 20mm...I use a Chinese made copy of the model GG-1.

I took the opportunity to take the G1 out today with the 20/1.7 lens attached. Still had a bit of hunting that the 14-45 lens doesn't do, as if, under certain circumstances, the lens decides to focus the wrong direction at first, then reverses and goes the correct way. Not a show stopper; I also used manual focus a bit on the indoor shots, which worked very well.
All images in-camera JPEGs using the dynamic B/W mode, ISO200.

Just got mine today as well, ooofffh, is this an amazing lens or what?
sharp as a straight blade razor, man-o-man is this the lens for the G series ...
very impressed, first couple of images.

Nice pics, JoeV, and I like your blog too. I have the same typewriter and enjoyed that David Foster Wallace quote.
I was a bit surprised to see that Photozone.de didn't like this lens more--he posted a review yesterday. He's rather exacting in his standards, but still--he complains a bit about corner softness.
FWIW, I like this lens because its rendering (barely noticeable corner softness included) reminds me of a rangefinder lens...except totally sharp in the center at 1.7. There aren't many lenses at this price for any system which are indistinguishable in the center at 1.7 and 5.6.

Looks a capable lens but is there barrel distortion?

Looks like practically zero.

I'm expecting mine tomorrow, and plan to take it to Italy next weekend, attached to my G1. I'm thrilled with the Images you guys have posted. I think I'm going to be very pleased !

Is that with or without software correction? Easy enough to do in post I guess for us EP-1 guys.
Just a question too, are those corrections made by the GF-1 is you shoot in RAW?
squirrel$$$bandit

Yes, the GF1 does apply corrections to RAW--or rather, Panasonic has gotten Adobe to apply the corrections in PS/LR. I'm sure that chart is with software correction though--I haven't seen any unprocessed RAW yet, ie., from dcraw.

Yeah it is with software correction. Any Adobe raw converter will do it without you needing to do anything as well. The E-p1 will also apply this to both jpeg and raw files, just not the CA correction that panasonic does.

My 20/1.7 arrives tomorrow and a Heavystar hood with cap arrives the next day. I would love to have a funky rectangular hood someday.
Barrel distortions and CA are corrected automatically in jpegs. The RAW file contains correction data for SilkyPix. Lightroom also reads and applies these corrections. The data is sent from a chip inside the lens to the camera. This means any M 4/3 camera will apply the barrel distortion correction. Uncorrected RAW files may be observed with other RAW converters.
Based on my experience with PTLens and Nikon RAW files (Nikkor 12-24/4 lens), barrel distortion correction does not produce noticeable (if any) cropping. Perhaps PTLens auto-crops barrel distortion corrections (it does not auto-crop perspective distortion corrections).
At least Panasonic and Olympus give you the barrel distortion corrections for at no extra cost. Nikon NEFs – even those from their most expensive lenses – require the purchase of additional software to fix lens distortion problems.
The advantage of the Tessar design is compactness. The disadvantage is edge sharpness. The DP Review data also shows the edge sharpness performance wide open is not awe inspiring. At f 2.8 edge sharpness looks fine. Because of the sensor size, I don't plan to stop down below f 5.6. Of course the only thing that matters are the prints. I'll report back after I use the lens for a while.
The Leica 25/1.4 would certainly give better wide open performance. But it's angle-of-view, weight and price are very different.

Picked up my 20/1.7 at the P.O. today. It's waiting for me at home. I forgot about ordering a hood (I knew I had to, but I procrastinated--I never thought the thing would ever ship!)

I am in the same boat. I am waiting on an expense check. Amazing how profitable driving to Philadelphia can be.

Thanks for motivating me to do my next expense report. I've bought a bunch of OM flash gear with the last cheque, not to mention a new universal remote (a half-decent one is not cheap, a good one VERY not cheap!) and am soon to acquire Sevres-Babyon's unloved olive F802.
