    Looks good. If you need any lenses check the classifieds.

    Re: Pen F to G1 adapter

    how do the pen lenses perform? Is there any line they are 'comparable' to?

    Is the focal length equation the same on the G1? IE a 25/2.8 pen lens is basically a 50mm FOV on the G1...

    Yes, multiply the focal length by 2 to get the effective field of view.

    IMHO, the Pen lenses are great on the G1, there are quite a few threads with photos here. I've tried 20mm to 250mm. Of course, I shoot film on Pen Fs, too, so it is really handy to have lenses that work on both.

    They are fabulous. There are no comparisons.

    Got cha Too bad there is nothing below 20mm... They may be awesome but there is so much impressive vintage glass >25 it makes my head spin!

    Re: Pen F to G1 adapter

    The really nice thing about Pen glass (besides the good imaging) is the small size which fits 4/3 very nicely, with none of the ergonomic compromises of cine lenses for example. No fumbling for aperture or focus rings that are too close to the camera, etc. They also focus very close, unlike M-mount glass, and they are reasonably priced.

    Sure, there are tons of other options. But in key focal lengths, they are difficult to beat. For example: 40/1.4...the only thing that compares is the Nokton 40/1.4 in M-mount. But the Pen focuses to 14", the Nokton to 27". The Zuiko is generally cheaper, and has better bokeh.

    The 38/1.8 compares very favorably to the Summicron-C 40/2, very similar (pleasing!) bokeh, and again close focus is much closer.

    Re: Pen F to G1 adapter

    I started using the Pen F lenses from day 1 because of the mount and I already owned most of them.

    The c-mount lenses (especially wides and superfast normal primes) are hard to beat by any brand or line of lenses in terms of size and performance.

    Ergonomics is not a problem. If anyone can use a G1 and its fiddly little buttons to focus, there is little to complain about the ergonomics of the c-mount primes.

    Re: Pen F to G1 adapter

    Vivek, you have to admit that the Pen lenses have better ergonomics than many of the cine lenses do (such as the Xenoplan that you pointed it out to me.) That's not to say they are unusable, of course, just not ideal ergonomics. You are right about the G1's fiddly buttons!

    Robert, Yes, the handling is better (the Xenoplan 25/1.9 sucks when it comes to that, No contest there.).

    Here is a teaser for milapse:

    Just to be clear- the Xenoplan 25/1.9 (and the 17/1.7) are easier to use on the Rabe adapter and is a pain to use with the Hawk adapter.

    Also, the image quality from the feather weight 25/1.9 Xenoplan is way better than the pen F 25/2.8.

    I now use several other c-mount 25mm lenses, including the superb Computar-TV 25/1.3 lens.

    I haven't seen the Rabe adapter, but I agree on the Xeno, it's great.

    Vivek, just out of curiosity: How does the Computar compare to the Canon 25/1.4 in quality and sensor coverage? And where would I find a Computar? Oh, and the 12.5mm I have needs machining, how about the 25mm?

    Sorry for leading this astray...

    Re: Pen F to G1 adapter

    Stefan, Yes the 25/1.3 mount needs to be trimmed (a nail file did the job for me)- it is already mentioned in the list Robert put up.

    Very slight corner vignetting (about 1mm) wide open with full coverage of the sensor. Vignetting (or light fall off) is gone by f2.8~f/4. Three bladed iris. None of these bother me.

    Filter size is 40.5mm and the front element is not deeply recessed as in many other 25mm c-mount lenses. It is tiny and <100gms in weight. I bought mine used. I believe it was discontinued a while ago.

    And people say the G1 can't shoot action photos.

    Another using the 38/3.5. This flower is about the size of a quarter, to give a reference as to the size of the bug.

    Brilliant

    Is he landing on the moon, or maybe somewhere more close to home?

    That's the Pink and Purple Pollen Bar, very popular around here.



    This one is getting it all over him, kinda like me when I have BBQ ribs.

    Good to see you cutting loose, Robert! Very very nice!

    I think the purple flower is a type of thistle.

    Beautiful macro shots Robert. What was your approximate working distance for these shots with the 38mm lens?

    Regards,
    Carl

    Re: Pen F to G1 adapter

    Thanks guys!

    There isn't much working distance...at close focus (1:2 ratio, about 6 inches from the sensor) this is only about 2 inches from the front of the lens. The tiny bug was about close focus distance, the butterfly was probably a couple of feet, that shot is cropped. The bees were probably 3 inches from the lens, guessing...

    I was fiddling with 100% crops and found this tiny creature.
