Best close up filter for DA 55-300mm

I would like to buy a close up filter for my DA 55-300 to try macro photography.
Here are the filters which I have considered:

Hoya HMC +3 or +4
Hoya Pro 1 digital +3
Pentax T95

Will there be a big difference in IQ between HMC and Pro 1?
How many diopters would be best for DA 55-300?

IŽam especially interested in Pentax T95 filter, because it`s on 50% sale right now, but I can not find any information about it. If someone is using T95, please let me know how it performs.

I know that many users of this forum use Raynox DCR close up filters.
How does Raynox DCR performs compared to filters listed above?

Basically, closeup lenses come in two categories: achromats, and next to worthless. If any of the above are non achromats, you can eliminate them from consideration immediately. Of the achromats, I'd assume they're all probably good enough. Finding one in the right filter size for a good price would probably trump other concerns. The Raynox 150 and 250 are nice, but small, and probably vignette in some cases. I'd also consider the Marumi achromats, not that I've veer them, but they seem to be available in a variety of sizes at a decent price.

As for what diopter strength to use, that depends on how close you want to be to your subject, and how much magnification you need. But +3 or +4 presumably puts you into 1:1 territory at the end.

In addition to the Raynox, the Canon 500d is good but relatively price, probably ~ $80 for a 58mm one.

The Raynox DCR-150 works beautifully on the 55-300mm, giving you up to 1.4:1 macro and excellent IQ. The Raynox 250 is a very poor match for the 55-300, with serious vignetting throughout the middle range of the zoom.

The magnification range for infinity focus is the diopter times the focal length in meters.

Hence:
+1 diopter on the 55-300 is .055-.3X -Too weak!
+10 diopter on 55-300 is .55-3X -Too strong!
+5 diopter .28-1.5X -'Bout right!

So far as I know there is no close-up lens better than the Raynox DCR 150 for your DA 55-300mm. I believe it is an apchromat (corrected for chromatic aberration at three wavelengths - a triplet.) I observe minimal vignetting using the DCR150 - DA 55-300mm combo with an APS-C camera; here's the worst case (wide open at 55mm - photo of laptop screen) - the graph is the intensity along the yellow diagonal line.

EDIT: I just checked & vignetting is worse at 100mm wide open, but stopping down fixes that.

Thank you for your replies.
IŽam now down to two filters, Raynox 150 and Marumi DHG achromat 200.
Both are equal price and diopter, but Raynox lens is 49 mm, but Marumi
could be 58 mm, same as the lens thread. would it be better to have the filter same size as the lens thread, or there will be no difference?

Actually, the Raynox is 43, but its clip on adapter lets it be mounted to much larger lenses, or you can use a stepping ring as some of us prefer. Anyhow, the only difference the size would make is the amount of vignetting, which is why you should pay attention to the post above showing the worst case scenario and decide if you could live with that. I think it wouldn't be problem - you wouldn't normallybe shooting at wide open aperture or at the 55mm end, and apparently the slight vignetting you see above goes away when shooting stopped down or toward the long end of the zoom.

But while there are lots of people here using the Raynox, there's no one I know of using the Marumi - would be interesting to have someone be the guinea pig :-)

how much is the Marumi? I might consider getting one for the long end (300mm) and see how it does. I'd be a willing guinea pig if the price permits it.

Seems they went for $60-$70 when I had seen them, but finding them is the trick. As far as I can tell, they are a relatively new product so being out of production isn't the problem - they just don't seem to have much of a distribution network.

I have decided to buy the Marumi DHG Achromat 200, because all reviews that I have found are very good. And I like that it`s screw on and I can get it in 58 mm thread.

Pentaxor, if you get one, please post some samples. I`ll do the same, but it can take a while because of the long shipping time.

So does this mean with the raynox, you need to buy some sort of adapter?

Thanks

The Raynox comes mounted in an adapter that allows use on any lens with filter threads sized between 52 and 67mm.

I'm going to chime in and say that I wouldn't recommend a close up filter. The amount that you will pay for a good one puts you way on the road to a real macro lens and I don't believe that the results are going to be as good as either extention tubes or a 50mm lens reversal either.

I totally agree with you keyser, but I think close up filter is still the best way to go for me. And the reason is very simple, I don`t shoot macro very often. And I don`t want dedicated lens for macro, because I mostly shoot on my travels, and IŽam not willing to carry around one extra lens for weeks just to shoot few macro shots. But filter is small and easy to fit on lens, just for those rare moments when I need that powerful magnification.
I have considered both reverse adapter and macro extension tubes, but I will not have AE metering with reverse adapter or extension tubes, but it`s a must be for me. And how do you stop down DA 55-300 with extension tubes?
But if you know any extension tubes with electrical contacts, please let me know.
