While the screw-driven, slow-aperture, and less-than-razor-sharp 55-300 zooms are certainly not first choice for serious birding, I have found my smc DA copy perfectly usable for casual grab shots of the kind shown below, all hand-held, EXIFs given.

BTW, provided there is sufficient light, I'm getting pretty decent results from my copy even at 300mm and F6.3, and even better ones at F7.1. Stopping down further makes it more likely to end up with a shutter speed or ISO setting that may compromise any hoped-for gain in overall lens sharpness. Not only that, it may also make your bokeh unnecessarily busy.

+1 with clackers on pre-focus. It will help a lot in practice.

Agree, get the shutter speed up and aperture stopped down. General rule of thumb for hand held is the shutter speed should be at least the inverse of the focal length, so for a 300mm, 1/300. For birds, which move really fast, even when sitting there - they twitch - notice the blur on the feet of the bird on the right - 1/500 and up is even better. The 55-300 isn't a bad lens, but it needs to be stopped down a bit. I find my copy performs best approaching f11. Technique and patience is key with birds. Pre-focus as much as you can. Also, shoot in RAW and start working with post processing, so you can go up to higher ISOs and have more tweaking options to clean up the image.

Your 2nd example does look quite good. Nevertheless, using a faster shutter speed as others have noted is always a good idea, both in terms of being at the limit of what SR can do at long focal lengths, and the subject movement. Even when a bird moves its head or body slightly, they move with great speed.

There's also the matter of greatly reduced depth-of-field in long tele shots, especially when not at or near infinity focus. Even a slight body movement by you as you press the shutter release can throw focus off. The reduced DOF alone is a good reason to stop down, preferably to at least f/8 while maintaining higher shutter speed. This means a boost of ISO setting, which in good lighting will not likely be excessively high. At a moderate distance with a 300mm FL, f/8 will probably adequately defocus the background, otherwise to shoot at f/5.6 it is best to use a tripod as normhead suggests, if that is practical for you.

If you shoot RAW, there are many different software that will help to sharpen your image in post. There is no substitute for faster shutter speeds, smaller aperture, and critical focus, but whether you use Photoshop or Lightroom or Nik Collection's Sharpening app, in moderation, it will help to take some of the softness and loss of detail. Here's an example from your jpeg.

Whereas, coatings aside, the smc DA(-L) and HD DA WR versions share the same optics (12 elements, 8 groups), the new HD DA PLM WR version is a completely new design (14 elements, 11 groups). As far as consumer telephoto zooms go, all four iterations seem to perform quite decently, with the PLM at a slight advantage, if at the cost of a slightly-slower widest aperture.

Correct. I should have said same basic IQ.

The real advantage I notice for the PLM version is the really fast focus. Once focused I really do not see much to choose between them. I have found both very usable once focused.

The older DA-L and DA HD WR 55-300mm have quite long focus rotation design, which is slower for AF, especially when going from a near to a far point. If working at various points, all at similar distances, focus is much faster. Also, the longer rotation is better for fine-tuning MF. The newer design has a shorter focus rotation for quicker response and a quiet DC motor, instead of being screw-driven, and has internal focus, which tends to shorten effective focal length at closer distances. Your bird might not fill your frame as much, being more like perhaps at 250mm instead of 300mm.

I used the original version for some years, then bought the HD WR, giving away the older one. It had damaged filter threads, but works perfectly. Even though having the same optics, I noticed a slight improvement in image quality with the added HD coatings.

Pre-focus on the top of the pole, because the birds are unpredictable.

Yes, I'd go 1/1000s, and be accurate with your focus, Mehulmandan ... even the metal post is blurry. Your second pic's focus is fine, for instance.

The shutter speed is too low, it makes motion blur, try 1/500 or faster.
The AF also missed the scene, you may need some calibration or just better technique. (Calibration is at the C menu's last page if I remember correctly.)
The 55-300 WR is not so sharp at F5.6. F8-F11 would be better int these scens where the background is far enough.
The K-30 handels the noise well up to ISO 1600 and even ISO 6400 is acceptable in some situations, so don't afraid to bump up a little bit.
The K-30 can do much better images with the 55-300 WR lens.

Oh, and AF-S with prefocusing may be better for this type of photos.

great shot, as already mentioned above - a bit away from the noise and the photo will be good - for such a small and fast birds, you made a good photo

Very cute bird, nicely caught!
Hm, maybe sharpness could be tweaked more, so that it doesn't sharpen the noise, but sharpens the bird. If you are using LR, play with the Sharpness, sharpness radious, and also masking. Hold Alt while you move the slider for the image to highlight the changes. don't be afraid to push these sliders ;) Its a great photo, doesn't have much to critique

the grain in the blur part of the photo is distracting, I think this photo could be denoise greatly to have a smooth look :)

First of all the subject is fascinating...had no idea there was such a bird, as bee eater.....photography wise what I like...and this is all personal choices of course...is the depth of field and the simple, elegant composition...very nice framing as well.....the photo does seem a little soft however, I am not sure if this is a lens issue,or something to do with the steadiness of the shot...or perhaps the speed you are shooting....a faster speed and perhaps...for the lens..if it is wide open, a slightly smaller apereture..might give some more clarity...the only suggestions I might have for post would be to look at the highlights..they seem slightly much..but again that is personal taste...you might also want to explore what happens if you gve some white...after lowering the highlights and take the black down...slightly to give some more contrast....I hope there's something useful in there for you...it's a nice capture...
