@L0n3Gr3yW0lf Not so sure about that.

This photo was taken with my E-510 + EX-25 + 50-200 at 200mm. Turned out OK.

...proving that tubes aren't just for extreme macro.

In the studio I used to use a short tube on a tele lens if I needed a tight head shot.

We are blessed with the insane close focusing of lenses like the 100-400 (did I mention somewhere I have a 100-400? I think I may have once). It's not always been this way.

I do admit that the article I learned that information was quite old (about 10 years ago) and most lenses were not designed for close miminum focus distance unless it was a macro or 3rd party lens, Tamron and Sigma had the reputation of having close focus capabilities more often the major brand ones.
This has changed quite a lot and both Panasonic and Olympus have introduced close focus capabilities on most of their lenses including the zoom lenses.

On your example the Oly 50-200mm had a pretty good minimum focus distance on its own (compared to the same era Canon and Sony 100-400mm or Nikon 80-400mm, can't remember the specs for Pentax DA* 90-250mm) and adding the extension tubes helps quite a bit as well. I'm not saying they are not worth it though.

Greywolf,
The article may have been ten years old but I think the logic is still sound. All maths is approximate in the following.....

To get 1:1 magnification with a 25mm lens you need 25mm extension tube...not a problem. With a 200mm lens to get 1:1 you need 200mm extension - this results in several stops light loss.

However with a a 200mm lens you only need 5 diopters close up filter to get 1:1...a Raynox DCR150 will do it. But with a 25mm lens you need 40 diopters...that's five Raynox DCR 250s!!

So tubes are more practical on a short lens, close up filters on a long one.

Focus distance is another story and depends on the particular lenses.

Not sure if you know this, and I do apologise if you do), but extension tubes are most effective with wide angle optics while magnification optics (Raynox for example) works best with telephoto optics and if you use them the opposite way their effectiveness is decreasing at square power.
No offence taken at all, and thank you for your thoughts. Whatever the case, I love to tinker and play with rules so I will try anything once :), and if I get the picture I want by being different then I don't hesitate to do so. That's the advantage of being unschooled in the science of photography - I don't have to worry about what other people say....lol

I must say though that I have seen plenty of people using tubes with long length lenses, and I have used my Raynoxes on my P12-32 and PL15 quite happily. I know that some people like to be quite methodical with their photographic practices, but I do love to bend rules. There's one fella over on the 'other' forum who uses tubes, a teleconverter AND stacked Raynoxes to achieve his targets. That's kind of the direction I might be heading for the project I have in mind.

A possibly counterfeit B+W polarizing filter from CL FOR $30
I did the exact same! For $30 too.

Except it was from EvilBay instead, nominally shipping from Hong Kong? B+W SLIM MRC Digital CPL. Somebody seems to have taken legit photographs of what looks like the real product. Fairly likely not the seller's own picture, though... :hmmm:

Bought my first ever UHS-ii card. No idea if there'll be any noticeable difference, I guess until I shoot some sports I won't know. They still aren't cheap, either. Mind you, compared to XQD they are! Something to consider for future camera purchases.

Yeah I kind of deserve this one though.

I won’t bore everyone with the details but it’s been a saga finding the perfect CPL for my 8-18. Part bad luck and partly (probably mostly) me just being way too anal about it.

I decided that the only CPL I’ll settle for now is the B+W kaessman because the other one I have is amazing. But I’m not gonna pay full price. I found this one on CL and everything checked out. But then some odd things about the box, it doesn’t look exactly like my other kaessman, etc.

The weird thing is if it’s fake it’s a damn good fake and is better than the preceding few I tried from urth, etc. The other funny thing is it was such a mission to haggle this lady and get into her gated neighborhood and it turns out she lives in the biggest mansion I’ve ever seen. If it is fake I will say there is money in these counterfeits.

It was bought new in 2019, has 1639 shutter actuations, and the flash is fired 13 times... Only drawback is that it is not black, but hey-ho, I live well with a silver one for 150 bucks, when the only black one in the classified was well used and asking price 400 bucks. Oh, and it also came with the OEM handgrip... The GX880 is rather chunky beside it. 20 minutes drive away for the pick-up, so it was instant consumer gratification as well. :biggrin:

and that's why the 4thirds 70-300 is tough to 'upgrade' from. Bulky yes (though not greatly more than native :mu43:), but f/5.6 and 1:2 closeups at 300mm. That's just silly bonus talent to throw into a telephoto zoom!

Photography adjacent, at least;
I bought a Spyder 5 screen calibrator (used).
I realised just how inaccurate my manual calibration attempts had been 😬
Literally seeing my previous edits in a whole new light.

I bought a Meike 50mm f1.7 (manual focus lens) in Nikon Z-mount for use on my Nikon Z6

I've always been a big Nikon fan - there, I've said it - and have had at least one Nikon amongst my kit since the mid-80's. My longest-serving Nikon digital camera has been a D700 (bought in 2012) which continues to work perfectly, and will have to be prised from my cold, dead hands. I did yearn for a modern iteration though, and been looking at a camera which will be good for landscape photography.

My Olys (E-M1.2 & Pen F) will remain my 'go to' of choice, maintaining their position as my favourite cameras. I still think there's a certain 'something' about them which makes them a joy to use. I may invest in some longer glass too.

Anyway...this beastie arrived yesterday - Z7 with the Z 50-1.8S:
