This lens arrived the morning my son was competing in WGI finals, so I threw it in the bag and headed to Dayton.  Seats were in the nose bleed section of the arena and the lights were out. The attached pictures were the first pictures I took using this lens and were taken with the lens fully extended.  I was very happy with the way the lens performed.  Pictures turned out great. There was  slight motion blur in pics with fast action, like the one with the kid doing a backflip, but otherwise the pictures were perfect.  This is the perfect camera lens for getting shots at your kids' activities and the price is definitely right if that is what you are looking for.

I am thrilled by this lens' performance. I use this lens most of times with my Nikon D40. It produces very sharp images. It is so convenient that you barely miss any shots within a large zooming range. I choose this lens over the combination of 18-50 and 50-200 for the comparable image quality and no need to swap lens. This lens plus the 35mm F/1.8G (for portrait and low light shooting) would suit most of amateur's and semi-pro's needs.

I really have been pleased with this lens. The pictures I took were clear and sharp. I gave this lens four stars because it's auto focus was a little on the slow side. It's manual focus was quick and easy to use. I came close to not ordering this lens because of some of the negative reviews. I am glad that I didn't let them discourage me. Now that I have purchased, and used the lens, I see those negative reviews as a little on the harsh side. I have used this lens to photograph college, and minor league professionalbaseball, and for some pictures of birds.  I would recommend this lens too others who are in need of a good telephoto lens like this, and have a limited budget.

It is a fabulous lens. I started to take photos with it, and the results were unbelievable. Honestly, I was worried it would be a regular cheap lens, but the autofocus is something in this lens. I highly advise everyone to have this lens.

Prior to purchasing the 70-200mm f/4 L IS I've had mixed results with telephoto lenses.  This lens has shown me what a truly great telephoto can do for my hobby.  The first thing I noticed was how bright the view finder was.  My photos displayed great color and contrast when using this lens.  Focus is incredibly sharp compared to my previous telephoto experiences.  Even with the IS I prefer to use a monopod because I feel like the camera is moving with that lens hanging out front.  Now I don't know how I got along without my 70-200 f/4 L IS.  A great addition to anyone's bag for those who take their photography serious.

This lens does great with my D750.  I bought the refurbished version of the lens through Emmy Photo and it came with a 3 year warranty and the product is amazing.  Ever since I've received it, I've been using it non stop and it has been impressive so far.  It's a bit heavy, but it's a great all-around lens especially if you've got a shoot and you're doing a lot of walking.  The autofocus is fast and quiet and I really like the way it performs in low light (see picture).

The lens is outstanding. It has an extreme quality feel when handling the lens. It zooms so smoothly within the housing. It has superb image quality at all the zoom settings I've used. The IS works well on the Panasonic G7 that I tested it on. It seemed about 2 or 3 stops. I also tested it on an Olympus OMDEM5 and it worked great there with the IS turned off. I also tested it on the GX85 and was amazed at the superb 4K video where IS is finally functional. The lens seemed a bit heavy for that camera but it did work very well for images and video.

The other great feature is that the lens is weather sealed and that all movement is within the housing. This is actually a good arrangement because other lenses that extend that are weather sealed can have seals fail and allow dust or moisture to enter. Another benefit to the lens movement within the housing is that there is no extension of the lens that can create an imbalance as you zoom the lens. This is a problem that I encountered using the 14-140 zoom lens on the Panasonic GX85 which makes it much harder to hold camera when zooming.

The lens was very sharp.at all zoom distances and showed great detail through the entire image no matter what the zoom setting. Tester claim it's sharpest at F3.5 to F4 but I found the F2.8 setting very sharp and used it a lot especially in lower light situations. I love the F2.8 setting as you get a beautiful bekoh especially if your subject is close.

The one downside is the lens is not inexpensive. The Panasonic lenses are usually excellent quality and this lens was even better than expected. Is it worth the premium price? I had my doubts before before buying the lens, but once I saw the high quality images it produced with careful focusing and settings it is indeed worth it and I'm glad I purchased it..

I ordered this lens and unfortunately had to return it. I was aware I was buying a used lens but decided I need to buy a brand new one. When I contacted the seller he was very quick to respond and went out of his way to make sure I was happy. I highly recommend using this seller and will not to hesitate to order from them again.

Excellent lens. I was happy to find that the lens actually looked and functioned like brand new, exceeding my expectations for  a lens described as "refurbished" by the seller.

I've had this lens for a few weeks now, and I have been very happy with it.  The optical quality is outstanding, and it performs well over its full aperture range.

I am very happy with this lens, not RAVING MAD happy, but satisfyingly pleased.  I'm going to try to make this review as balanced and objective as possible.

I've been using the lens for about a month now, at home and on vacation (so it's been quite a lot of pictures woohoo).  I've used it in many situations, some of which you might say the lens is not made for, but I'm just trying to give an all-around review in as many scenarios as possible.  Here's how the lens, in my opinion, plays out.

THE GOOD:
- Excellent general purpose lens.
- 30mm focal length creates a wide enough angle for most situations.
- Images are pretty contrasty and pleasing.
- Reasonably sharp in good and even mediocre light.  And for the casual photographer (like myself), it's more than sharp enough, especially considering the breadth of its applications.
- The 1.4 maximum aperture is GREAT for low light situations and can also be used to blur out the backgrounds of photos to accentuate the subject (however, see portraits in "The Bad")
- The HSM focusing mechanism works well with my camera and is reasonably fast.  (Faster than my 18-55mm, but noticeably slower than my other Nikon primes)
- The focus ring is just stiff enough.  You'll be holding it often, so the stiffness helps keep you from manually focusing when you don't need to.
- In my opinion the lens looks pretty stylin' on the camera haha.

THE BAD:
- I would not advise using this lens for portraits if you are serious about it.  The angle of view requires you to move close to your subject and sadly stretches out his/her face.  For portraits, please use the 50mm or longer.  (however, if you're shooting 3 people at a dinner table, it's totally fine)
- Can't focus very close, making macro work difficult.
- No Auto/Manual focus switch on the lens (must be switched in the camera.
- Sometimes (and this is in practice) the lens fails to focus well in low light situations, make sure the lens cap is off.
- The rear lens cap is terrible, throw it away and buy a Nikon one.

OVERALL:
This lens can be summed up in two words: GENERAL PURPOSE, don't forget that, GENERAL PURPOSE.  Don't expect super stellar pictures, but I'd say this lens is indispensable for traveling and general photography.  It's awesome performance in low light is especially great for people who hate the destructive effects of the on-camera flash.  Hope this helps :)

I bought this lens few weeks back as i wanted a all in one lens for my travels where i do not have the liberty to keep changing lenses. Overall i would rate 4 out of 5 in terms of the performance of the lens.

Just a small issue with the piece i got was i found a minute just or something similar which is visible on my pictures like a patch while i am at 18mm.

I purchased this lens for a trip to France so I would not have to lug around more than one lens. After taking over 1000 photos I am very satisfied with the results that I got using this lens. Other than forgetting to unlock the zoom, it is a good lens.
