Sony 30mm macro lens + wet Inon lenses, why it dosen't work?

08 March 2014 - 02:50 AM

 

I just bought Sony nex5n together with 30mm lens for macro. On the front of the port I can put adapter for M67 thread. 

I do not have too much experience with macro, I prefer WAL but because I still have some lenses from my compact camera I simply put in on the front and I took some pictures ... then I found that there is no significant difference with inon UCL165 and/or UCL330 and without them.

Is the reason for that is just short focusing distance of the 30mm lens or what .... I am a bit confused.

What kind of wet lens You can recommend me to get a bit more than 1:1, I want to take super macro pictures.

 

I have limited time (just 1 week) before next trip, so is the idea to buy telephoto converter x2 for land use is the good idea or just stupid?

 

 


Sony RX100 versus Sony Nex5n

23 January 2014 - 01:58 AM

Is there anybody who can estimate or try to compare the advantages and disadvantages of that two setups:

 

1. Sony RX100 in Aquapazza housing + InonUWL H100+dome unit  versus 2. Sony Nex5N in Aquapazza housing with Samyang 8mm and dome port ??

 

RX100 is a bit smaller

Nex 5N offer higher ISO

 

When I compared image sharpness of the 16mm pancake lens + wide angle converter on Nex5N with RX100 and Inon wet lens, then I did not found too big difference. But the Samyang 8mm lens seems to be a bit better, and would give wider view, instead of the RX100 plus Inon. 

 

Disadvantages of Samyang 8mm is 30 cm focusing distance and manual focus.

 

Please give me some arguments to change the system or not. 

I am interested mainly with WAL. 

 

 

 


How important is CCD size?

14 January 2014 - 01:10 PM

I started UWP just few years ago with compact camera Oly XZ-1. With small strobes and Inon lens I can do images sharp in corners at f around 4. Then the same lens I attached to Sony RX-100. To obtain similar sharpness and constant Iso=100 I have to close aperture up to f 6 or 8. Now I started to think about changing for DSLR. In tests of lenses I see that wide lens has to be closed to f 14 or 16 .

If I want to get sharp images in the corners, what is the advantage of bigger CCD like FullFrame ??

When I am looking for new lens I always check the resolution and sharpness diagrams and lenses like Tokina 10-17 dosent looks so great.

 

Even if the question sounds stupid or basic, please be patient to give answer. I am really in doubt.

I want to sell my equipment, but I would sell green part, only when red and blue will be sold as the whole packages.

 

I am looking for the DSLR, but if I cannot find good option, then I want to keep my setup. I am still searching so the setup should be available for sell in two weeks.
