Pascal Garnier Posted March 30, 2014 Author Share Posted March 30, 2014 Henry, it's not the same as the one I got. Unless you find a detailed review or footage of the one you mentioned, your guess is as good as mine. Quote Link to comment Share on other sites More sharing options...
Bioskop.Inc Posted March 31, 2014 Share Posted March 31, 2014 cool go for it!!! $50 & $60 immediately declined! Must have been an automated response - whatever happened to good old haggling? Said i could only make 1 more offer - strange? Perhaps $80? Quote Link to comment Share on other sites More sharing options...
Pascal Garnier Posted March 31, 2014 Author Share Posted March 31, 2014 that's standard ebay practice : you can only make 3 offers max. and most sellers only accept offers higher than 90 or 95% of their Buy Now price. Quote Link to comment Share on other sites More sharing options...

Ahh I see - you used to be able to haggle. So how is the Focal Reducer really - are there any other real downsides now you've had it a few days? I offered $80 yesterday still not had a reply..... Well that means they might accept - $80 must be their min limit, as my 2 [stupidly low] offers were declined almost a split second after hitting the offer button. V.rude not to even consider an offer! Quote Link to comment Share on other sites More sharing options...
Shane Essary Posted April 1, 2014 Share Posted April 1, 2014 I am *very* interested in seeing how the m42 adapters do. Helios, Jupiter and Tair.... :) Quote Link to comment Share on other sites More sharing options...
Bioskop.Inc Posted April 1, 2014 Share Posted April 1, 2014 I am troubled that the glass, on the M42 adapter, seems very close to the aperture ridge/lip & they state that some lenses with protruding back elements (at infinity) may hit the glass - so obviously a no no. I've asked the question about the distance of the glass from the top to see if this will be a problem. But would be interesting to see some results before buying, but it is only $100 & the Metabones people are really dragging their feet getting an M42 or EF (which i understand is more difficult to make, apparently) adapter out there.

andy lee Posted April 1, 2014 Share Posted April 1, 2014 I am convinced that this FD to micro 4/3 speedbooster is exactly the same one Pascal has bought it is just cheaper from a different seller on ebay looking very carefully at both sets of photos it is identical , every screw every part of it the lettering font etc There cannot be multiple manufacturers of this adaptor just different sellers on ebay selling at competative prices this one is $96.00 http://www.ebay.co.uk/itm/360844545884?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 Quote Link to comment Share on other sites More sharing options...
Pascal Garnier Posted April 2, 2014 Author Share Posted April 2, 2014 andy : there's a big chance they use cheaper glass, which is the only way to make it cheaper. Which might introduce all kinds of artifacts. That's why the Metabones is so expensive : they use the best glass they can get. I didn't buy the cheapest adapter, but paid $30 extra for something that had already been tested/reviewed with pictures to proove it. The only way to find out how this cheaper one does is to buy one and see how it does. But all tests I've seen so far show there's a huge difference and image degradation with the very cheap focal reducers. IronFilm 1 Quote Link to comment Share on other sites More sharing options...

I recently was researching this stuff and found myself discussing it with folks on Personal-View. Apparently, much of the housings are mass produced between manufacturers, but the glass that gets installed is not necessarily equal. Its a quality control issue, much like many things out of China that are mass produced on a budget. 2 products from different companies can look identical, but not necessarily perform the same. I saw tests from the "cheapo ebay" models on that forum, and they did not perform as well as the RJ. On a whim, I decided to use the contact form to shoot an email out to RJ, and it seems like I got a personal response from Rong Jin himself. He was actually extremely informative and helpful, we started discussing coatings and quality of the glass, and it was pretty clear to me that this is a guy who takes pride in his product. I do believe he puts in a better quality glass element than the others. IronFilm 1 Quote Link to comment Share on other sites More sharing options...
Nikkor Posted April 24, 2014 Share Posted April 24, 2014 I've send them a suggestion for a medium format focal reducer, I have totally failed to do one on my own (it has terrible aberrations, and only 0.6x reduction), I want to use my glass digitally without spending millions on MFDB Quote Link to comment Share on other sites More sharing options...

RJ also do a M42 adaptor, which is coming to me sometime soon i hope: http://www.ebay.co.uk/itm/Pentax-M42-reducer-speed-booster-turbo-adapter-to-m4-3-GF5-GF6-GX1-EM5-EM1-BM-PC-/360827529560 Quote Link to comment Share on other sites More sharing options...
Julian Posted April 25, 2014 Share Posted April 25, 2014 I'm looking for a Canon EF to M43 Focal Reducer for a good price. Doesn't have to be the cheapest of the cheapest, but around €100 would be nice. Planning on using it with my DSO FF58 2x oval (f/4) on the GH4. I'd prefer buying something that is tested by others. Suggestions welcome! Quote Link to comment Share on other sites More sharing options...

This looked pretty good, but the guy said it was an RJ but then claimed it came from Roxsen, so had the blue spot problem (the new RJ doesn't & he'll take an offer of $90-98): Julian 1 Quote Link to comment Share on other sites More sharing options...

Inazuma Posted April 25, 2014 Share Posted April 25, 2014 Can someone clarify something about aperture equivalence for me. The focal reducer will increase light gathering by one stop, but how will it affect the DOF shallowness? So 35 f2 lens on mft would become 25mm f1.4, and then multiply again by the mft crop factor, it becomes a 50mm f2.8? Quote Link to comment Share on other sites More sharing options...
Cassius McGowan Posted April 25, 2014 Share Posted April 25, 2014 I have a Nikon 50 1.4 Nikkor-S. Would the focal reducer work with it? This one was in his store. http://www.ebay.com/itm/Nikon-F-G-reducer-speed-booster-turbo-adapter-m4-3-mft-GF5-GF6-GX1-EM5-EM1-BM-/360827485043?pt=US_Lens_Adapters_Mounts_Tubes&hash=item5402fe7b73 Quote Link to comment Share on other sites More sharing options...
