Mike, With infinity objectives I was using that lovely Nikon 200mm F4 on bellows then the Raynox 150, I think both were very good. In fact I was getting good results with Nikon finite M Plan objectives on their own. I haven't done any testing but I notice less CA with the Raynox 5320. I was using a ...

Here is a full image (was 5760x3840) re-sized to 1024 http://www.photomacrography.net/forum/userpix/2513_moon_full1_1.jpg and here is a 100% crop (actually the first image of the moon was a 100% crop as well). I can't say that my search for the best focus was really accurate but it's probably within...

I think that adds a lot of value to the thread. Is this wide open or stopped to mimic an objective? --Rik I just unscrewed the Nikon objective from the adapter ring - leaving an M25 size hole so it's probably around twice the diameter of the objective glass. I'll post a 100% crop in the morning . T...

I wasn't happy that my Raynox 5320 was at exactly the right distance from the sensor so I've just been out shooting the moon to get the focus on infinity. I'm using the same helicoid and tubes. I ended up with a distance of 198mm from the rear of the lens to the sensor - so there is about 18mm of th...

Mosquito eyes

Mosquito eyes. A stack of 170 in Zerene Stacker using a Nikon ELWD 20X Plan Flour and a Raynox DCR5320Pro as the tube lens.

Wow! I can't imagine how you took the photo of the pupa on the surface of the water - from the side! They are all amazing images. I love the stereos of the breathing tubes.

Very nice. I like the idea of stacking in groups and then stacking the resulting images to reduce artifacts, I’ll give it a go.

With these cameras in LV the mirror needs to cycle if you set the EX compatible flash in ETTL mode to measure the preflash but not if you set the flash in manual mode. The shutter needs to cycle in any case to provide the sync signal. Definitively the mirror produces much more vibration. With my no...

Hi David, That's a very nice result! As you noticed I'm also switching over to electronic flash , primary to capture planktonic animals but expect that pictures will generally improve. Hakan and Charles recently posted very good examples of similar objects made by flash and without stacking. Good l...

I’ve just tried it in manual mode with mirror lock, as Charles suggested (I haven’t used that before) and that makes sense. It is certainly quieter on the second press than when using live mode. At the moment my set up isn’t par focal so I will have to address that as well. I can’t reduce the length...

Thanks for the comments. I’m still a bit confused Charles. I know I can still select quiet mode on my 5D MK III and 40D with the flash attached but I thought that, if in live mode with the flash attached, the mirror will re-cock. I know that it makes more noise and vibration with the flash attached....

Thanks Pau. Yes, that is exactly what I’m thinking - I’ve been reading those threads and Charles’ recent post. I'm still trying to understand some of the potential issues. I know I can’t use silent 2 mode on my Canon if I want to trigger a flash. I overcome this on my macro set up by using a long ex...
