I am a professional photographer, but didn't really "need" this lens for my daily work. I was just enjoying photographing birds and this was a "cheap-by-lens-standards" impulse buy.The lens surprised me, and I've been impressed by it. I was worried about f/8 at the long end, but the compression at 400mm still allows for the semi-shallow focus look. It's harder to get a great image when the light is low, and performs best on a sunny day. I've paired it with a Canon R5, so at least the sensor does well at a higher ISO. At first I thought the AF was a little sluggish, but I think it might've been my own user error, had good luck with eye AF settings, able to grab focus on little, erratic birds.The lens is SUPER light, which I love. The lack of weather sealing worries me, I live in Hawaii-it is humid- but I toss it in a dehumidifier box after a misty day. If I continue with bird photography and actually sell images I'd probably invest in the 100-500, but for now, this is a great lens to play with.

The L says it all. Colour rendition, AF, build quality... It's a wonderful lens. Absolutely value for money. Would recommend it whole heartedly. There are a couple better options. But only if you put in much more cash.

I have a pretty significant number of components in my DSLR kit (as listed below) and this bag proved to have adequate space for all the components, with SPACE LEFT FOR MORE!List of components that found a place in this bag:1) Nikon D3300 dslr2) Nikon AF-P 18-55mm Kit lens3) Nikon AF-S 50mm Prime lens4) Nikon AF-P 70-300mm Telephoto lens5) HB-N106 Bayonet Lens hood (for kit lens)6) HB-47 Bayonet Lens hood (for prime lens)7) HB-77 Bayonet Lens hood (for telephoto lens)8) Altura professional dslr cleaning kit (including blower, lens pen, lens brush, lens cleaner bottle and microfiber cloths)9) 1 pc. ND2-ND400 variable ND filter with case10) 1pc. 55mm to 58mm step up filter adapter11) USB OTG Smart card reader12) Mobile OTG cable13) DSLR battery charger14) Nikon WU-1a WiFi adapter for Nikon DSLR15) 1 spare Memory cardAnd trust me when I say this that if organized properly, this bag can still fit a couple of more lenses (I can still fit 1 telephoto lens and 1 prime lens). Refer to my attached photo for evidence.There is provisions to attach my tripod (Snapgear 50inch foldable) at the exterior side of the bag, but I would not use that since it wkuld make it extremely difficult to swing the bag from my back to front (using the sling function) when I need quick access to my camera.Pros:a) This bag is smaller than it looksb) has more space than I need to fit all of abovec) Is extremely well padded from all sidesd) Dividers are of good quality and completely customizable (i.e. we can fix them at any position inside the bag as per our requirement).Still, I took a star away for the following reasons.Cons:a) not water-proofb) No water-proof cover provided eitherc) Chains are of acceptable (but not excellent) quality...felt like needs to be handled with care.

Superb fast lens, highly recommend, slower AF than kit lens but still a superb

I use a Nikon D3100, I bought a Nikon 50mm f/1.8D AF Nikkor Lens. That lens has 58mm threads. I bought the 58mm Tiffen Circular Polarizer filter to use on that lens. At the time of my order it was sold and fulfilled by Amazon. I paid for shipping and received the filter in less than four days. The filter came in a hard plastic box that I use for storing the filter. It looked new and works fine. No filter problems and I give it 5 stars. The only issue is screwing it onto the lens is a bit tricky because you only have half the width to work with but I blame that on my fingers and lack of any real nails. I have noticed that if the filter doesn't go on straight it may make a glare effect but when I see that, I rescrew it on and that takes care of the issue.

I use this extender with my 70-200/2.8, 300, 400, and 500mm tele lenses for wildlife shooting (hobby). My cameras: 7D, now upgraded to a 7D II, and a 5D III. Important in particular for 2x TC users: both latter cameras still provide an active center field autofocus with lens+TC combos that have an F/8 initial aperture. In particular every birder knows: you can't get enough focal length. And if you don't want to invest in - and carry - a super huge & heavy 800mm lens, you have to have TC's in your backpack. I use Canon's very good 1.4x MK III TC frequently, and less frequently this 2x TC. Many reviewer's here explained already the 2x TC's technical pros and cons in detail. In real life, according to my experience, you can break it down to those three items that really count:(1) images lose visibly sharpness and get softer, in particular in the edges (full frame) but with re-sharpening during post-processing (or sharper pre-settings in your camera) you can get acceptably good results (= you still can see feather/fur textures) IF...(2)... there is enough light available (!!) for a - with many lenses - quite slow combo AND...(3)... the object does not move too fast and unpredictable, because AF will work as sluggish as an old digital compact camera (but accurate with a carefully micro adjusted camera).This may also be important for you:- Oh no, you can't combine Canon's Mark III 1.4x with 2x TC's to shoot man's first footsteps on Moon from Earth. Canon prevented this mechanically, not only by some sort of pins (you could easily remove): the whole TC's do fit because their lens systems extend from their bodies and would collide before their bayonets snap together. Don't complain, be sure that the image quality of such combos would be too lousy anyway for modern high res sensors. If you need extreme focal lengths check if digiscoping (mostly without AF) would be the better solution for you.- Some lenses do not fit with Canon's Mark III TC's because, again, their extended lens systems would literally collide with the back lenses too close to the bayonet. The example in Canon's lens line that I presume is most prone to such a disappointment is the macro lens EF 100mm/2.8 L IS USM. So check the TC's compatibility with the lenses you want to use it with before you hit the order button. Btw you can pimp your macro's magnification by using extension tubes, plenty of good ones with full electronic supply of AF and aperture are available.Final word(s):Given the fact that a 2x TC is always a quite extreme optical compromise, the Canon engineers did a decent job with the Mk III version. But do not expect any wonders. An EF 400/5.6 lens will always be much sharper at 400mm - and focus much quicker - than a 70-200/2.8 II + 2x TC III combo, I can tell from my own experience.Those who just start with the TC business, I'd highly recommend to go first for Canon's 1.4x TC Mk III. It provides less reach but much better optical and AF performance. In practice you can use it much more frequently and get good results.

I'm not going to post images because every lens can take a sharp image (nearly). The IS and AF are awesome though and that's a great reason to pick this up. Way better performance than the RF 50mm 1.8

I own an EOS R but have mostly been using EF lenses. I decided to spurge on a Canon RF 85mm F2 Macro IS STM and a week later it was on my doorstep. My first impressions is it’s build very well: excellent fit and finish, sturdy plastics, metal mount and quality switches and rings. The manual focus ring is silky smooth and ideal for focusing macro subjects.On camera, my optical impressions were equality good: sharp edge to edge from macro to infinity and well corrected for distortion. Use of the lens profile isn’t needed in LR as the distortion and light fall-off are almost invisible. And no flare problems with blazing Hawaiian sunsets! The 0.5x macro is great for flowers and small products, delivering crisp details consistently, albeit bokeh was on the busy side. Hybrid IS provides amazingly smooth stabilization compared to the EF lenses of yesteryear.Focus is accurate and surefooted, rarely missing on my EOS R. When I carefully place individually selected AF points where I desire focus the result is consistently sharp images. I don't trust auto AF selection or zone focus for macro since the camera doesn't have a clue if you prefer the flower center or petal in focus. Single-point AF is especially effective for macro because it allows a precise lock on a small detail whereas a full-sized AF point may overlap multiple details.The only small negative is the auto focus motor is on the noisy side for a modern design—something I was aware of before purchase. Normal focus adjustments and movie servo emit wee creaking sounds. Granted the camera is against your head so it seems louder than it is, but the motor and sliding lens elements actually emit a robotic whirl if cycling from macro to infinity. Not unpleasant but loud enough to be picked up by the built-in mics during video. Use an external mic if you plan video. I normally do anyway (Sennheiser Shotgun mic), but something to consider. With that said, the sound is usually inaudible for your subjects.Some have stated that AF is slow, but that hasn't been my experience. In normal use, the STM drive is nimble, surefooted and locks on almost immediately: plenty fast enough for landscapes, macro and portraits. For movie servo focusing during my video blogs, it was fast on my EOS R. Obviously this optic is not intended to be a sports lens. Like most macro designs, it uses front element extension to focus and is by nature slower to focus than a rear element or internal focus design typical of USM lenses. However, the only time it seems slow is when refocusing from macro range to infinity. If you’re not using the macro range, keep the distance limiter set to the normal range (.5m to infinity) and you’ll avoid that little toil.No hood is included so I bought the JJC ET-77 clone: 90% of OEM quality at 20% of the cost of OEM.All in all a lovely lens: sharp, well corrected for distortion, little or no flare, solidly built, surefooted auto focus and reasonably priced.
