quality step up rings?

Hello dear Pentaxian,
I would like to know where I can find step-up rings from 49 mm to anything that are VERY solid?
Thank You to let me know.
Kind regards.

Early last year I bought a set of step-up and step-down rings by K&F Concept (see my original post HERE). They're solid, the threads are well cut and finished, and I've been very happy with them so far. Much better than any other rings I've owned

What is your definition of "solid"?

Step up rings are made of either polycarbonate (the most likely to cross-thread or break), anodized aluminum (the most common), and brass (the most durable and considered the most 'reliable').

Both Heliopan and Sensei make brass step up rings, but in the 49mm+ sizes, you're looking at mostly Heliopan.

I prefer using BHphotovideo because of their selection, competitive prices, and it's easy to filter the parameters of what I need on the side bars of their web pages.

That is another way of asking what you are wanting to do that requires a robust ring.

LOL! I was wondering myself since unless you are stacking them to act as a hood, how much stress does the average step up ring need to withstand?

Thanks! (BHphotovideo is quite expensive for me because I am living in Europe)

It is for a 55mm (or a 52mm) sigma ring flash...

Go for the brass or well made aluminum models since that is a bit more weight than a filter. Probably not a huge amount but well machined threads are nice to spread the load bearing area around the lens.

The K&F Concepts rings are aluminium but very strong, with no "flex" like the awful generic / unbranded types . They'll work well for your ring flash, I'm sure.

Ohhhh...I would like one of those.

It is a real shame that adapters for 49mm are not included with most ring flash. I agree that a brass adapter would be desirable since it is often a pain to thread the flash onto the lens.

I would not see the ring go away and smash on/to the ground

Thanks, seems that they are sold in packages (could be useful also with my 67mm lenses)

You're welcome

Honestly, the sets are so inexpensive that it's worth the small outlay to have multiple sizes on hand, just in case... especially since they can be stacked, so (within reason) it's possible to step up and down between most common sizes.

Good luck with your ring flash! Let us know how you get on?

I bought fotodiox rings, and they seem sturdy to me. Haven't used them a whole lot yet, but it's made out of metal and they have a quality feel to them.

There is free shipping for order bigger than 25$, I thing I will go for it
For the flash, I will need to find some tutorial on that specific model and then...My learning curve will be for Macro and portrait And probably some LBA aftermath
