Hi, thanks, I'll naturally go to the wider aperture too as it contains the smaller too. I agree, the difference between 2 and 1.4 is usually double in price, and the less common 1.2 can sometimes skyrocket. These days I look into really old glass, my favorite one right now being the Nikkor 35 1.4 from 1971. Cheers.

@@yeisonmanco9261 dépende de las condiciones en las que guardes los lentes, si son propicias para el desarrollo de hongos, volverán. En menos medida supongo pues se habrán eliminado pegantes que pienso yo, los hongos utilizan como alimento. Saludos.

Hi, yes, I added the link on the video description. Best.

Hello, I can add very little to your analysis as it is totally spot on. I also have the 105mm AFD, and like it a lot, I usually take it when I need an all rounder. The ones in the video are legendary lenses, the 105 f/2.5 is super sharp and color rendition is fantastic. The f/1.8 eis even sharper and produces great bokeh, the dream would be to have the three merged on a single lens.

Hola, no conozco el nombre tecnico que esos conectores. Saludos

@@srfurley it's a very interesting lens, maybe a bit too small. Never tried it with flash myself, the results are good? Cheers.

Hi, I don't know, the one I have installed is Nvidia Quadro m2200m, I hope this info is useful. Cheers.

Is it 82 mm X 70 mm (type A) or 105 mm x 82 mm(type B) ?

@@user-oj1ng4pv4i hello, it's mxm-a. Best

My opinion may be biased because I prefer prime lenses. We'll with the 50 1.4, you'll be two stops faster than with your zoom and that can make the difference in low light conditions. You'll get more bokeh if that's something you're interested in. Best.

@@diyextravaganza thanks, i'm looking for a better bokeh, maybe better colors, sharpness or some caracter to a prime lens. This 1.4 may not be that sharp but gives some charms to the pics you've done. My Zoom for the job, versatility, efficiency, and a few prime lens for better result and a bit of fun. Thanks for your answer and good day ^^

@@hyperion2502 you're welcome, if you have the budget, I recommend the 58mm 1.4G, it has what you mentioned ,test it before buying because it is a love it or hate it lens. I personally love it.

I did that? LoL, I did not have any loose parts at the end, so the answer is yes.

Hola Fernando, es gusto es para mí de tener subscriptores fieles como tú. Saludos.

Saludos hombre !

Hi, I configured them to act as one, using the suitable adapter. If I remember correctly, it was not allowing me to select both in such situation. I cannot test since I changed GPUs a few months ago, I'm using a single Quadro RTX 5000 now.

@@diyextravaganza Many thanks for your answer. Do you remember if both GPU were working (especially, if for large meshes both memory were used) ? I'm preparing to put a new workstation to the budget, but I hesitate with a few options. Either RTX 4000 Ada (or slightly better), or rather cheaper models but 2 or 3 of them (e.g., RTX A2000 12 GB or RTX 2000-Ada 16GB). Depending on the models, I could plan to buy 1 first and then upgrade to 2 or 3 (even for the 4000 Ada). As far as I know, Ampere chips (A2000 etc.) support NVlink, but not Ada Lovelace chips. I'm unsure how the native GPU solver of Fluent behaves with several GPUs, especially for Ada generation.

@@tea-hash-sea Yes both where used, in case where mesh was big enough to require it. However, this seemed to limit a bit the performance as you have both GPUs exchanging info. For this particular reason (and because I found ridiculously cheap), I upgraded to an Quadro RTX5000, and I've tested it with the native GPU solver and it is lightning fast. I made a video about it, but you saw it already as you put a comment there. Cheers

@@diyextravaganza Thanks for the info!

@@tea-hash-sea You're welcome. Keep connected, I'm planning a series of tutorials, even if you seem to know your way around it never hurts to have a refreshment on the basics.

Hi, glad you appreciate my videos, feel free to aks questions anytime. And yes, please share my channel with as many friends as you can.

Hi, I don't think the design of the yongnuo is particularly new (but I haven't checked), the 50mm prescription is well established by now. About the Nikkor getting better, I did not paid attention to be honest. But in my opinion, the Nikkor offers the best trade-off quality price out there. Best..

Merci beaucoup; le "mauvais jeu des mots" m'a bien fait rire. Je trouve que la plupart des contenus sont biaisés (pour de$ raison$ évidente$), je prefere rester neutre et m'attacher aux faits. Je te souhaite une excellente soirée, et n'hesites pas à partager avec tes amis.

Je vais voir ce que je peux faire. Il n'y a pas des sous-titres ? Merci

Excelente dato, muchas gracias, ya fui a ver su canal y ví muy bonitas imagenes macro. El 18-55 es un excelente lente y muy abordable. Menos durable que los lentes más onerosos pero esa es la vida del lente kit. Saludos.

Gracias hombre !

Hi, this one is pure rubber as far as I can remember. Best.

the isopropyl alcohol is 99%, the hydrogen peroxide is 30%?

Yes, 30% but less easy to find. You can use smaller concentration and put a bit more instead of the distillated water. Best.

@@diyextravaganza thank you

@@diyextravaganza bro，I would also like to inquire if it is possible to use only the previous reagents and not use the hama lens cleaner，Will the effect be different?

I've never got good results with the fungus removal solution for a final cleaning. I guess you cannot find the hama one easily, you can try this one amzn.to/45DHq7c

Yes, that's it. Just pay attention if marks need to be done for focusing, it's all explained on the video. Cheers.

Thanks a lot my friend!

Hola, ves el tornillo que quito para retirar el frente? Ves que en el parasol hay un agujero? Alinea el agujero del parasol con el tornillo, mueve el parasol de arriba a abajo hasta que veas un tornillo que está escondido, retiralo y podrás retirar el primer anillo. Comparte este canal en tus redes sociales y con tus amigos. Saludos.

Hi, I've never tried to remove the button. I generally try to be careful around it since the alcohol erases the markings. I'll try to find the repair manual to see how it removes. Please write me again in case I forget. Best.

Hola, no creo. Tengo Uno desde hace rato esperando para abrir, lo haré ya luego. Saludos.

For the haze, you need to do many many times, it will go away eventually. For the fungus, can't you add a little video on your TH-cam? Best

I'll do the vídeo and post here after

@@fabiosales2985 Hi, I saw, for the haze, you'll need to insist on the cleaning, the next group is tricky because it is sealed and near impossible to open, I usually replace it altogether.

It's called Canada balsam. Best.

@@diyextravaganza can i use B-6000???

Je le dis dans la vidéo je crois. Bref, c'est skf lglt2. Cordialement.

You're welcome, don't hesitate to share with friends!

Great info, thanks for sharing!

Hola, yo casi todas mis imagenes las hago con objetivos antiguos, uno de mis favoritos siendo el Nikkor 35 f/1.4 de 1971. Me gustan mucho más, pues dan imagénes que tienen un "yo no se que" que los lentes modernos fallan completamente en procurar. Este lente en particular no lo he utilizado mucho pero me parece es popular entre los fotografos, lo que he escuchado es que hay un factor suerte con estos lentes, unas copias salen maravillosas y otras insipidas. Un saludo.

@@diyextravaganza muchas gracias por tu respuesta, muy valiosa para mí. Un saludo.

Hello, correction, is SKF LGLT2

The SKF LGMT 2 is not very adapted for lenses, it tends to separate a lot (meaning, separation oil from thickener), leaving a stiff focus and oily diaphragm.

Oops, sorry for the mistake and thanks for the correction.

@@fernando0854 I agree is not easy to retain those letters, even more when references change substantially due to one single character.

Hi, glad the video is spot-on for you. About the cyclop, if I ever cross paths with one in need of help, absolutely. Don't forget to share with friends !

Gracias hombre, un abrazo !

Hi, my guess is that besides the bayonet the construction is otherwise the same, so, yes. Proceed in any case with care and do your markings at each critical step !

Normally you must put in the same position as there is a small groove to receive the set screw. Otherwise, you'll deform the thread. Best.

@@diyextravaganza Thanks! I'll mark it to be safe :)

Hi, isopropyl alcohol, 99.9% pure. That's all. Best.

Great, hope you manage without trouble, I think the video is explicit enough, but if you have questions, do not hesitate. Best.

I did not have the 1.8, which is think it is slightly more uncommon than the 1.4 or 2, at least where I live. Best.

No, the D90 is a very different camera, I've done it already, more difficult though. More important, it has 2 pieces of glass, so the filter (quartz) , must be 2mm thicker. Best

Es un fantástico lente, si cuentas explotarlo al máximo si, si es para dejarlo sin usar, no. Hay que pensar que el tipo de imagenes que te va a generar es algo particular y que no vas a poder utilizarlo en toda situación. Saludos.

@@diyextravaganza me encanta siempre experimentar, aparte de ser Nikonista hasta la médula 😄 me gusta coleccionar también, son maravillosas piezas de ingeniería 👍👏🇦🇷

Entonces no lo dudes, el 16mm Ais es una pieza un poco rara, y bueno, esos lentes si los conservas bien, tienden a conservar su valor. Si consigues en Argentina piezas interesantes para restaurar?

@@diyextravaganza si, de vez en cuando sale por Mercado Libre, alguna publicación de algunos lentes interesantes, y este lente se ve muy bien 🇦🇷👏👍🤙

@@arielgajda3335 a bueno, yo empecé a reparar lentes para poder obtener excelentes lentes por una fracción del precio.

Thanks a lot, I'm not sure I've the repair manual, I need to check, and if so, where should I send it.

Gracias mi amigo !

Thanks amigo

Hi, for the link, it will really depends were are you located, for an alternative, you can look for a grease, with lithium soap thickener, and low viscosity (around 20mm^2/s ) at 40°C.

If the screw head is done, the real solution is to drill until the head falls and use pliers if possible, if not, drill the screw and re-tap the thread. There is really no easy solution. If the head still has something of a imprint, I use a big screwdriver to have a lot of torque and push with all my weight at the same time, I've put some acetone before, works most of the time. Best

The traditional one that has been used for generations is the "Canada balsam", this is the one I use.

Thank you! I'm in the process of separating a doublet for a tokina 80-200 2.8 but in the acetone method is taking too long I will try the oven method if no success in acetone!

It's is possible to separate again if any mistakes?

@@jhonatandavid9448 it is possible, but you have to go thru the whole process again, which is lengthy. Best

Thanks, feel free to share it with friends!
