Panasonic LUMIX G 20mm f/1.7 Aspherical Pancake Lens for Micro Four Thirds Interchangeable Lens Cameras

Very hard to find lens, it get sold out like in hours when it restock. Took like 2 months to get stock. The pancake lens is among the smallest lens you could find, no DSLR lens are that small, I believe first pank cake releaes was from Olympus for their third four camera.

I had GH1 and has only the kit lens 14-140mm. Is nice lens but is bit heavy, the lens is actually slight heavier than the body. GH1 body weight almost the same as GF1 except is bigger due to the flip screen, view finder and other input, you would get better deal for GH1 then would for GF1 one since price has been very close this day. But again you can't fit Gh1+20mm in your jacket then would be GF1+20mm.

The 20mm lens perform much faster indoor, excampe same shots in auto mode took 1/2 shuttle speed while with 20mm gave me faster 1/20. That gave you less burry picture, You could hear the motor noise when auto focus picture with 20mm, but not much with video, the af noise won't affect the video, unlike Olympus one, but again you make sure has the latest filmware. The AF is not as fast as the 14-140mm kit lens, but is still pretty fast. Manual Focus might be challege for right hand user... since lens that small you make sure wanted a filter so won't accident touch the optics when you do manual focus and other situation.

The Lens comes with bag and manual, no hood included. 7-14mm lens you can hood but not this one, i think hood could help prevent touch the optics...

Price is $400 is still bit high, $300 is more idea, consider the performance is about the same as Nikon 1.8 35mm that cost half less. But the lens is double the size and is for DSLR.

Hopefully this lens will be more common so price drop and be affortable for the masses. 20mm lens can help improve low light and indoor shooting, i highly suggest get video light like sima one for video, it help a lot. also a external flash for mainly bounce... bounce flash is something you can't get any where with build in pop up flash, bounce just gave you much nature, most external flash, cheap and pricey gave you about the same quality picture indoor unless the area is big when flash power come in play.

I have read a lot of reviews of this lens before I finally purchased. It has exceeded even my expectations. It really shines in low light situation without the need of a flash. The other week we had some great snow here in Georgia. I took my camera and tripod outside at NIGHT and came away with some fantastic shots. Two things about this lens which would not keep me from recommending it to others is there is no image stabilization and the lens is noisy when focusing. I'm really happy with this lens, and use as my primary one.

I will review the entire camera although i purchased this lens separately. I have several digital cameras including a fine SLR with 2 excellent autofocus zoom lenses but when i began taking pictures with the GF1, I was amazed at the results. The IA setting adjusts to shadows and other lighting situations in a manner that in inexplicable and simply amazing. In addition, this lens has excellent light gathering ability and can take pictures in low light situations without a flash assuming one does attend to the available lighting on the subject to some degree. My friends are amazed at the compactness of the camera with this lens and the features not to mention the amazing detail in the resulting pictures. This camera can also take movies and the quality is really good. When taking movies, one must be careful to move the camera slowly so as not to blur and confuse the video an all cases. This is something to become accustomed to with video as opposed to still photography. I was able to purchase this camera for a reduced price and it is not cheep but is well worth the cost, and from what i have read, the 20 mm lens is the one to buy. it is not zoom but the camera can magnify the pictures 2x or 4x digitally, and the camera has the pixels to handle this with good results. I also adapt the camera to use my older olympus OM and E lenses with excellent results.

i'm impressed with this lens and have read all the good things about it, not yet a negative. get this lens if you have a m4/3 system. or rather you owed it to yourself to get this lens if you have e-p1, e-p2 or gf1. this lens is a perfect pairing with my gf1 for everyday chores and travel with me anywhere.

I bought the 20 1.7 to go with my Panasonic GF1 and GH1 cameras, and this lens has not disappointed! It is so small and light, and the image quality is fantastic! I mostly use it with my GF1 as that combo is my go everywhere camera, but it also does visit my GH1 at times. The lens is sharp and contrasty, and the AF is quite fast even given that the lens does have to move some to focus. This lens has become a classic in the micro 4/3 world!
