Re: Samyang 7.5mm F3.5 Fish-eye

The general 'lazy rule' seems to be to focus to 0.4m on f5.6-f8 and you don't need to worry about focus. Must admit to not having tested the theory myself.. I've only used mine a couple of times as i'm not a massive fisheye fan!

Re: Samyang 7.5mm F3.5 Fish-eye

Done a bit of research and the Oly 8mm is a lot bigger & heavier than the Samyang and I would need use an adaptor too.

As I'll already have the 12-40 & 40-150 pros in my bag I think the smaller, lighter Samyang is the way to go for me.

Re: Samyang 7.5mm F3.5 Fish-eye

It's the Samyang 8mm I have (specs here), not the Olympus.. It's still bigger than the 7.5mm MFT version though so your point is still valid...and especially if you don't have already have a FT adapter!

Re: Samyang 7.5mm F3.5 Fish-eye

Just took a look at my options again & discovered the lensbaby circular fish eye. Unfortunately it doesn't give a full circular image as the image is bigger than a 4/3rd sensor ( http://m43photo.blogspot.co.uk/2014/...r-fisheye.html ). Shame because I like the effect it gives, especially the reflection on the edge.

How far down?

I've got a birthday coming up, too, but I'll be lucky to get a lens cleaning cloth!

Re: Samyang 7.5mm F3.5 Fish-eye

On holiday in Halkidiki at the moment and really wish I'd bought one. 20mm just isn't wide enough for scenery

Re: Samyang 7.5mm F3.5 Fish-eye

Woo hoo! Lens has arrived at my Mums, can't have it foe a couple of weeks yet. She wants me to test however, so I'm going to run around there tonight on my way home from work, just to check it out.

I remember reading somewhere that you have to change a setting on the camera (E-M1) to allow it take pictures when it can't recognise the lens / it dosent think a lens is attached. Am I right or am I thinking of a different camea? Anyone able to tell me where the setting is? I only as as a quick Google search came up with nothing & i don't have manual on me.

Re: Samyang 7.5mm F3.5 Fish-eye

My EM10 'recognises'* that it has a manual lens attached and switches to MF automatically, my EM5 doesn't! Either way you can take photos without making any changes if you are in A or P mode. I rarely use S and never use Auto so don't know what they do.

*recognises is a bit of a misnomer here at it has no electronic connection to the lens (As there are no electronics in the lens! )and merely shows 0mm in EXIF

Re: Samyang 7.5mm F3.5 Fish-eye

There is a way of setting the focal length to allow the IBIS to work accurately; if I remember correctly open the Image Stabilisation from the control panel and then press the Info button, the dials should then allow you to select the (nearest) focal length?

You have to make sure you only select aperture priority or manual exposure when using this lens; shutter priority and program modes won't work. Also, IBIS won't automatically calibrate as the camera does not know the focal length - you have to set this manually. I suspect this is the setting you read about.

I'm jealous - enjoy!

Re: Samyang 7.5mm F3.5 Fish-eye

Good point about IBIS - I've been using the lens quite a bit recently and had forgotten about setting that.

However, at that focal length I doubt IBIS makes much of a detectable difference at exposures below around half a second!

I just returned from 3 weeks in S Africa and Malawi: I took the 12-35 f2.8, 40-150 f2.8 and teleconverter as my main lenses, but slipped the 45 f1.8 and Samyang in my pocket. I took both my E-M1 bodies since we were doing a lot of game drives and I didn't want to risk changing lenses in the extremely dusty environment of an open Land Rover.

I didn't actually use the 45 (I'd intended to use it for 'street' portraits, but opportunities didn't arise), however the fisheye got used quite a bit for landscapes, especially sunsets. It was great fun to have around and is so small you don't notice the weight or size. Set to f4.5 - 5.6, roughly zone focus, then forget! I used a LowePro 200AW slingback bag throughout, which easily carried all the kit.

I've barely started processing the over-2500 images I took overall, but if there are any nice fisheye shots I'll post them in this thread.

Re: Samyang 7.5mm F3.5 Fish-eye

Will be joining the club too - really wished I'd had one on holiday and last weekend at the coast so jumped in as I had the money in my PayPal account.

Hope I get the hang of it - will need some experimentation I think

Yes, we've all found this. Keeping the fingers of your left hand and your feet out of the frame are the main problems (hold the camera with two hands on the body, rather than with the left one cradling the lens, and Liveview is useful for framing with the camera held out in front), and the deeper grip on the E-M1 puts your right fingers in the frame as well unless you're very careful.

I did quite a few shots handheld with the 3-shot 2EV HDR option, and I'm looking forward to playing with those.

Re: Samyang 7.5mm F3.5 Fish-eye

Thanks for the reply - manual mode, done that before.

Focal length for IBIS - need to work out how to do that. Does It reset when you put a recognised lens back on?

That's one of things I was going to try with it as well. Also going to try long exposure HDR with it.

Yes, but if you use another manual lens the camera remembers the last value you input, so you would have to change it to suit the other lens.
