Bellows aren't necessarily huge. My M42 Bellowscope is quite compact, extends to 110mm and weighs just 230g. With a lightweight 105/3.5 enlarger lens mounted, I feel a great sense of freedom.
Quote: Raynox 250 spec shows it to be suitable for 52mm to 67mm filter size. whereas FA43 is 49mm. will it fit ? is there any option to get 1:1 magnification ?
The rear thread of the Raynox optic is 43mm. I use a 49-43mm step-down ring to mount my Raynox DCR-250 onto 49mm-thread lenses.
Quote: Read a review of Raynox vs Marumi. and is stated Raynox as better option
I think that is the consensus, yes.

Thank you, thank you. As I mention there, any closeup optic, whether a corrected achromat like a Raynox or Marumi (Canon and Olympus also made these), or an uncorrected meniscus like those cheap +1+2+4dpt sets, shortens the focus distance. With a +4.8dpt Raynox DCR-150, working distance is about 16-20cm. For the +8dpt DCR-250, it's about 12-13cm.
Magnification depends on host-lens focal length.
M = F*D/1000 where M is magnification, F is host lens focal length, and D is dioptre of the add-on lens. So with your DA*50-135 @135mm, you'd get these magnifications:
* DCR-150: 4.8*135/1000= ~0.65x
* DCR-250: 8.0*135/1000= ~1.15x
Quote: curious to know, which (costlier) hardware you think minimize loss of AF and aperture control.
AF-type tube sets are rare and expensive, and AF isn't your friend when shooting macro. A-type tube sets, which retain aperture automation, are also fairly costly. One trick is to buy old A-type teleconverters and remove the glass. They then become A-type tubes. 2x TCs are usually around 25mm thick, so two of them behind a 50mm lens (like your zooms @50mm) give 1:1 magnification.
Be aware that any extension eats light. At 1:1, any lens loses 2 f-stops. An f/2 becomes effectively f/4. Raynox and other closeup dioptres do NOT cut into the transmitted light.

suggest a good achromatic lens for this lens
Modern 90-100-105mm macro lenses go to 1:1 magnification so you won't need an achromat -- unless you want to go FURTHER!! My test with a 90mm macro plus the Raynox DCR-250 shows that at full extension it reaches 2:1.
Here is my take on modern AF macro lenses: They are great general-purpose tools, good for general tele work and very sharp headshot portraits as well as macros. If you need a general short tele, the DFA100 macro or its ilk are very tempting.
But I'm a cheap bastard; my M42 Vivitar-Komine 90/2.8 macro cost me all of US$3 shipped. (I had to replace its decayed focus grip -- with DUCT TAPE!) I use that and my other 'macro' lenses (28-40-50mm) mostly for close work, not general shooting. I do much of my macro and general work with cheap ultra-sharp enlarger lenses on extension. Great cheap fun!
