Hi,

 

I would like to buy cheap 50mm lens for canon ef mount to use with my ZWO Asi 294MC Pro. I would love to buy famous Nifty-fifty, especially because I can buy used one even for 80 dollars, but as I understand it can not be used without electronics to change focus at all and to set the aperature. Is there any version of it which can be used fully manually?

 

What are your other options?

 

I would like a cheap lens - best below 140 dollars (can be price for used ones).

 

Best regards,

Piotr Zatwarnicki

Do NOT get the Nifty-fifty - Gen1.  The image quality is very poor for astro work.  I don't know about the Gen2.

You could try a Yongnuo 50mm f/1.2

This. I have this lens and for astro work its not very good. Lots of coma and elongated stars in the corners. I use it mostly as a travel lens.

Or maybe save up and go for a Rokinon lens. Full manual 50mm f1.8 can go for $500 new. Maybe less used. They have better optics than a nifty fifty.

Gen1 or 2?  How old is the lens and what f-stop are you using?  The quality is very erratic epically the all plastic ones..

Have a look at the Astromechnics lens controller for Canon EF/EF-S lenses, you will have full control of the lens.

 

The advantage of the Canon 50 1.8 gen 1 is that it has a switch for auto / manual focusing and has a metal mount. I have not heard they are poor for astro as mentioned above but you will need to stop any of these cheap 50mm lenses down a fair bit maybe F4, don't use at F1.8 or you will be wasting the night!

I think the problem will be simmilar - it is autofocus lens. 

 

I would like to go with samyang 50mm, but in Poland even used ones are pretty expensive (more than 300 dollars) in comparison with canon Nifty-Fifty. I saw many chinese lenses (7artisan, ttartisan, Meike), some had even good astrophoto reviews, but the are all only for mirrorless systems, and those few ones for dslr are much more expensive (about 300 dollars).

I will use it with Asiair Pro, so Astromechanics are not available unfortunetaly. Do you know if I can somehow change aperature with gen 1? And of course I know I can't use it wide open - I thought about f3.5. I already own old russian Helios 44m (58mm). It is usable from f4, almost great from f5.6, but wanted something a bit faster.

Its a gen 1 I'm pretty sure. I picked it up in maybe 2009? I've had it a while. Maybe the quality is just my lens but I mostly carry it for travel and street photography. It pairs well with my 6D but I no longer shoot astro with it. I have several Rokinon lenses I use for that now.

You could probably add a stack of stop down rings to reduce the aperture externally couldn't you?

I don't think you can change aperture that's why I suggested the Astromechanics lens controller, maybe with a smaller sensor you can get something at 1.8 with a lot of cropping? I would hate being tied into something like the Asiair though I know they work well.

 

I believe the gen I has the same optics as the gen II but the gen II has a  plastic body but I could be wrong. I know when I bought my 50 1.2 they gleefully told me the 1.8 was sharper stopped down that is!

I think I will stick for some time with Soviet lens and buy something better later. But what can I buy later - is Samyang 50mm f1.4 closer to legendary Samyang 135mm f2.0 or it is closer to much worse Samyang 85mm f1.4? What are other more expensive manual options?

I thought you wanted a 50mm FOV, the stand out lens for me is the Canon 200 F2.8 you will find loads of great images taken with this lens. I personally would never buy a manual only lens for astro focusing is tough!

 

With a full frame sensor will need a bit of stopping down but APS-C or smaller can probably use it wide open.

Nifty 50's have a terrible manual focus. It is more of an autofocus lens, the MF is real sloppy and has no grease resistance.  I have seen some decent nifty 50 images.  You can expect with any cheap lens to have to stop down.

 

Personally IMO if you are going to stop down to F4, there are a large range of lenses that will put up a useable image. I own 2 of these Pentax 50mm F1.7's  They are crazy cheap and perform pretty well at F4 on APS-C.  It has a manual aperture and the focus ring is very smooth.  You need a Pentax k to EF adapter. Get a good adapter that allows infinity focus.  You also should buy a 49mm to 76mm step up ring and get an aluminum 76mm hood which allows you to use a dew heater without messing up the focus.. This might be another $15 on ebay.

Here are some images taken on APS-C with the pentax

Thanks!

 

The images looks great :) I heard these lenses are very good, but finally I see images done with them. I can buy Pentax - A 50mm f1.7 for 80 dollars in Poland (don't understand why they are more expensive here) or Ashai Takumar 55mm f1.8 (m42) or Ashai Takumar 55mm f2 (m42). Are they any different in astrophotography performance in comparison with Pentax lenses?

FYI - Not sure how it performs for Astro but the Canon Efs 60mm macro (f2.8) is one of the sharpest lenses they make.

Im not sure what the difference is honestly. Can you just pay shipping on ebay and buy from the usa?
