@Psyfurius For completeness sake, since no one as yet has mentioned it, let me also mention another tiny but important acquisition.
Good quality filters for your lenses (I think both of your lenses will take 52mm size filters). The Circular Polarizer and Neutral Density and Graduated Neutral Density filters will take your pictures to a different level. The example you have given might very well have been shot with one or more of these filters screwed on top of the lens.

[/quote]I own both polarizers and a ND but I hardly ever use them. The polarizer I just didnât find to many uses for in practice (looked very artificial to me), and in cases Iâd use the ND I just stop down and then stack a few exposures.
Results in less noise & no weird color shifts. It doesnât work for everything but it covers most of my needs.

So, what do you think guys? Should I need a âultraâ wide lens for landscape or should I stick with my 55-200 mm ?
[/quote]You definitely donât need it but I think you might enjoy it. 
Really nice photos!
I think the general case behind all of this is that very little gear is needed to take great photos. With a bit of creativity and effort a lot can be accomplished with basic tools. There are a lot of nice options around but youâll have to find your own set of tools you enjoy using. 
Thanks for the clarification.
Which extension tubes do you recommend? I found this two online:
Kenko Auto Extension Tube Set

Vello Auto Extension Tube Set
https://www.bhphotovideo.com/c/product/787224-REG/vello_ext_nd_auto_focus_ext_tube.html/prm/alsVwDtl
I donât mind if they are auto focus or not. I can focus manually, doesnât bother me. So which should I get? Or do you guys have other recommendations on extension tubes?
I do have a Polarizer filter and some Neutral Density Filters along with Gradual Filters. I bought the Polarizer at Best Buy ( http://www.bestbuy.com/site/insignia-52mm-circular-polarizer-lens-filter-clear/5926314.p?id=1219174625252&skuId=5926314 ) and the Neutral Density kit from Amazon ( Amazon.com ).
Thanks! Thatâs a great picture! A lot of details. Iâm looking forward buying extension tubes.
Thanks for the advice!
And thanks everyone who enjoyed my photos 
Thatâs what I own. They work fine, but are IMO a bit pricey for what they are. My guess is that youâll be fine when using the vello ones.

Unless you have mechanical lenses youâll probably care about being able to adjust aperture. 
So I went to this site ( http://digitalphotographylive.com/macro-extension-tube-review-kenko-vs-vello/ ) and they did a comparison between Kenko, Vello and a Non-Brand extension tube. One of the lines says:
The Kenko has no problem in use. Vello and Non-brand works fine with Nikon Pro DSLR but not with entry level DSLR camera like Nikon D3100. When attached with Nikon D3100 it gives (F â â ) Error. Which indicates the electronic contact of camera body and extension tube arenât aligned properly.
So I went around the web reading reviews and yes⌠there are connection issues with the Vello extension tubes and level entry cameras like my Nikon D3300.
I think that I would buy the Kenko extension tubes at $129.00
If the contacts donât work itâs really a piece of cr*p. Something you cannot tell from pictures is the precision of the mount. If there is some slack your lens can be slightly misaligned. Not an issue with a light 18-55mm kit lens, more problematic with a three-pounds 100-400mm (worsened by the fact that youâll have to stack several given the long focal).
If you shoot macro hand-held you need AFâŚ
But IMHO, be on the cheap side (or even buy 2nd hand) for gear you donât know how to use yet(*), and be ready to reinvest good money on more professional stuff later once you have ascertained its usefulness.
(*) tripod, monopod, filters, flash(es), reflectors, close up lenses, extension tubes, macro lens, bag, shoulder strap, remote control, shooting tentâŚ
Not necessarily. I never used AF for my macro shots. Moving the camera back and forth and judging the sharpness in the viewfinder works very wellâŚ
Lucky man. By the time I press the shutter I have slightly moved and the focus plane has shiftedâŚ
Well, I am not saying that the first picture I take is the good one
Also, my D300+60mm macro are slow at focusing, so I have no real choice⌠but still I believe that with a bit of experience this is the best technique.
@Psyfurius Speaking of macro shooting: you could also obtain an adapter to make your Nikon accept semi-antique M42-thread manual lenses, made of real glass For example a Russian Industar 61 L/Z, which has a very long, smooth focusing thread/helix.

With adapters, the whole world is waiting for you 
I have read in many places that these semi-antique lenses arenât very adequate on modern cameras, because:
How much of this is true?
Hi @Ofnuts,
Well I have no technical evidence, neither for nor against those claims. I only know that I like the way semi-antique lenses behave/the result they give. I am sure that some proper googling will produce better replies.

In general, good old prime lenses behave more nicely than modern kit lenses.
I have used old âmanualâ lenses with adapters first for a Canon EOS 600D (called Rebel T3i in the USA), then on a Fuji X-T1. I just had to buy a new adapter to make my old lenses fit the new camera body.
@Psyfurius In order not to stray too far off from the original Nikon question: there are many fine old Nikkor lenses that still give a superior result: http://www.kenrockwell.com/nikon/nikkor.htm
