Hey all,

I've been eyeing the Venus 15mm F4 Macro for a while. I'm an ultrawide junky for many things, and it's significantly wider than my widest which is 17mm (on full frame). I was considering a 14mm F2.8 for a while but never comitted due to lack of normal filters, etc, and have zero need for F2.8. The Venus 15mm F4 on the other hand checks a lot of boxes, being even wider than 17mm, but still takes normal filters, and optically is great, and has macro ability on top of that for interesting potential. But I've never liked the price of the Venus 15mm. Also the Venus has a shift mechanism, which I'm not really in need of, when I shoot wide, I embrace distortion.

That said, I just noticed that Obteka basically has the same lens available, rebranded, without the shift mechanism, also being 15mm F4. Signficantly cheaper. $149 new actually. Made think at first that it was just not the same lens and moved on. But I went back later and read some things and people were claiming its the same as the Venus, without the shift. That intrigues me a lot. I don't mind spending $150 on a novelty lens that has multiple purposes. And I'd rather have a 15mm F4 macro than a 14mm F2.8 non-macro any day for the things I do.

Anyone know first hand or with a good source if these two lenses are indeed the same or at least close enough, just minus the shift?

Very best,

Have you tried comparing the optical formula...number of elements in number of groups... 'M elements in N groups'?

Both are 12 elements in 9 groups, both have one Low Dispersion and three high refractive aspherics, both apertures are 14 blades...sounds awfually like 'shift' is the real distinguishing thing

Everything points to them being the same, minus the shifter. But wondered if any of the macro group knew from hands-on-for-sure versus a bunch of vague stuff floating around the web.

I know the Venus is pretty sharp too, even wide open, corner performance seems decent. So for the $150 price tag, seems like a no-brainer.

Plus, Kurt around here can sell this lens, his 15mm macro work sets the bar. I've wanted an ultrawide macro lens after just seeing the perspective on those snakes.

Very best,

Thanks for the heads up on this. I'm been meaning to get the Venus 15mm f4, but the price, short working distance and lack of opportunities for wide angle macros for me personally this last couple of years had meant I'd cooled on the idea. But if these become available through a UK source at this price I might consider getting one. Be interested to see some user experience. Brian has been using the rebranded version of the Venus 60mm macro, and it seems the real deal, with excellent results.

Awesome! Thank you for the heads up. It's strange when you can get great glass on the cheap!

I haven't picked it up yet, but will hopefully soon. It's too inexpensive and functional not to just grab it up. Costs as much as a kit lens after all.

Gonna wait till after Hurricane Irma floats past to see what I have left before buying a lens, heh heh. :rolleyes::oops: :p

I got mine few days ago. And the first few tests were impressive, at least wide open and viewing on camera display.
The focus ring sometimes feels a bit strange, but have to get more images to tell someting more exact.

I just ordered one. I'm from the UK and had to order it from the US. It was with eBay worldwide shipping arrangement so I paid import duty etc up front. Not bad, because with shipping it was £150 British pounds, and given that the Venus/Laowa is £499 in the UK I could have got 3 of them and had £50 left. When I get it in about 10 days I'll test it and post some sample images.

By the way: In case you get one with adapters, for example for Sony E mount: First thing to check if the adapter screws are fixed. I did not, but noted some play.
Luckily nothing bad happend (blocking between adapter and lens or such).
All four screws where more or less loose, feels much better after I have thightend them.

I am very happy with the wideangel macro capability. Let's say between 1:2 to 1:5. For 1:1 it is ok for translucent materials. I think about a modification to get more light :-)

My tests as further distance wideangle on fullframe where bad, no edge sharpness widopen - but I suppose this is based on the loose screws adapter at this first outdoor walk.

I like what I get with that lens as wideangle macro. Still nothing to say about infinity or such, edge to edge sharpness.

That looks like a fun lens to shoot, curious to see more from it :D

I took the lens with me on vaccation:

- Sometimes the focussing ring needs very different force to be focussed down in the macro range. On some occasions I first thought it may be damaged ans stuck. Likely I have to open the lens soon to see if the rollers where OK.
- Some of my far away images (portraits in envirment) are partial unsharp. I supppose the adapter from EF mount to Sony E-Mount (which I got with the lens) could be tilted, or the lens itself has a problem. But nontheless, the images I got with with are great.

So at the moment the lens is good when I have more or less on object to focus on, but not good for example landscape.
