This is the training centre aka Outtakes thread of Day Prime 2019.
Maybe there are more people like me who want to get the feel of a lens (again) and experiment a bit.

Day Prime is a great challenge but there is a limited time slot for each FL. You have to be there on that day/in that week, or wait another year ...

This thread lets you post on other days too. And lets you post shots that you don't want to post in the main photo thread.

I haven't figured out if the aperture plates do anything for this circular fish or not. I have used the f/8 plate here but will have a go without aperture later.

Camera Model: ILCE-7
Lens: Lensbaby Composer and Fisheye 12/4
Aperture: f/8

I went to Delft to pick up my new wide angle toy. Determined to use it on film on my SRT101 and XGM. Minolta MD W.Rokkor 17 mm 1:4, the widest non-fish produced by Minolta. Wide open sharpness in the center very good, the edges are a bit smudgy (even at f/8) but in practical use this doesn’t matter as we do not view 1:1. MFD is a usefull 25 cm.

17.1: Delftse Poort

Camera Model: ILCE-7RM2
Lens: Minolta MD W.Rokkor 17 mm 1:4
Aperture: f/8
Exposure Time: 0.017 sec (1/60)
ISO: 160

17.2: Delftse Poort

Camera Model: ILCE-7RM2
Lens: Minolta MD W.Rokkor 17 mm 1:4
Aperture: f/8
Exposure Time: 0.017 sec (1/60)
ISO: 200

17.3: Canal-bridges of Delft

Camera Model: ILCE-7RM2
Lens: Minolta MD W.Rokkor 17 mm 1:4
Aperture: f/8
Exposure Time: 0.017 sec (1/60)
ISO: 250

Good stuff Paul, did you buy it from Fotohandel Delfshaven?
I have a Rokkor 17/4 as well and found it quite usable on my A7 and A7ii, actually much better than on my A6000 where the corners look more smudgy than on FF. I don't understand why but I just take what I can get. I'll be using it next week, and maybe tomorrow for some training if the weather is better than today.

I especially like your last bridge shot, very pleasing lines for my eye to follow.

Mind the bandwidth of others, don't link pictures larger then 1024 wide or 960 pix high, see here

Yes Pieter, the remarkable museumshop is the source. I love that place...

Same here, when I yell "Fotohandel Delfshaven" about half of my MF lenses will come to attention and salute

E 16 shot on Sunday erranding without converters

16.1 Bushwick street

not sure why the left edge is so nasty - maybe I never noticed how soft f2.8 is? although I wasn't completely straight with the ironwork either. hmmm. you learn something new every day(prime)!

Yesterday I went training with my two 21 mm lenses.

The first is a Tokina (with MD mount) 21 mm f 3.8. It's big (77 mm filter thread), big front lens, all metal and well constructed. I bought it for 10 € on a foto fair.

The second is an OM Zuiko 21 mm f3.5. It's small (49 mm filter thread), lightweight, well constructed but it cost me over 200 € in a second hand photo store.

None of the images is worth posting (basically brick wall tests to look at distortion, vignetting and sharpness).

Conclusion:

Vignetting is roughly the same at the same aperture, heavy wide open and pretty good from f8 onwards. Given the size of the lens and front element I had expected the Tokina to be better, but it really wasn't.

Distortion of the Tokina is a bit moustache but in lightroom using the profile for the Nikon 20/2.8D together with -7 manual distortion corrections straightens everything up nicely. Distortion of the Olympus is slightly better, more straight barrel with a slight moustache. Using the Minolta 20/2.8 AF profile without anything else makes the image look very straight

Sharpness, I guess the conclusion there is you get what you pay for. The Olympus is sharper with greater microcontrast everywhere in the frame at every aperture vs. the Tokina. Quite large zones of the Tokina corners are soft and mushy while the Olympus has very reasonable corners, full open still a bit mushy (but miles ahead of the Tokina at f11) and really good when stopped down a bit

Last but not least the Olympus is a little bit (~4%) wider than the Tokina.

So if anybody is interested in a 21 mm lens for just "playing around on day 21" send me a PM, you can have my Tokina for my out of pocket postage cost of sending it to you

There are high amounts of variation with the Sony E 16 F2.8 pancake. I posted some tests of three copies here, then gave up on trying to find a perfect one.
A68 30M 35 50 60M 16-50 16-80 18-55 18-70 18-135 55-200 55-300
A6000 LA-EA1 6.5 16 20 30 50 60 16-50 18-55 55-210
600si: 20 24 28 50 100M 135 24-85 24-105 28-105 35-70 35-105 70-210 75-300 100-200

You're right, and a mount conversion for this lens is not justified
